This application claims priority to and the benefit of Korean Patent Application No. 10-2021-0190557 filed in the Korean Intellectual Property Office on Dec. 29, 2021, the entire contents of which are incorporated herein by reference.
The present disclosure relates to a method for managing a database, and particularly, to a method for remotely managing a database.
As technology for using a remote database server which exists on a network through a computing device, database link technology may exist. The database link technology may also be technology for using the remote database server which exists on the network in a database server accessed by a user. The user may use an object which exists in the remote database server through the database link technology. The object may be, for example, a table in which one or multiple columns are gathered to constitute one record. The user may use the object which exists in the remote database server through the computing device. For example, the user may insert a record or row data into a table type object. As another example, the user may delete the record or row data from the table type object.
However, the remote database server may be a database server which other users jointly use in addition to the user. Accordingly, when the user arbitrarily deletes or changes the record included in the object which exists in the remote database server, difficulties may occur when other users use the corresponding database server.
In the conventional database link technology, access information (e.g., an ID, a password, or an IP address) to the remote database server may be stored in the computing device or the database server used by the user. As a result, there may also be a problem in that the access information to the remote database server may be exposed.
The present disclosure has been made in an effort to provide a method for using an object positioned in a remote database server.
However, technical objects of the present disclosure are not restricted to the technical object mentioned as above. Other unmentioned technical objects will be apparently appreciated by those skilled in the art by referencing to the following description.
An exemplary embodiment of the present disclosure provides a method for remotely managing a database performed by a gateway server including at least one processor. The method for remotely managing the database may include: receiving an access information registration request for using a second database server from a first database server; generating access information including first information for a first object usable by the first database server based on the access information registration request, the first object being positioned in the second database server; and transmitting a virtual object corresponding to the first object to the first database server based on the access information.
The access information may include second information for at least one first operation enabled to be performed by the first database server for the first object. Further, the method may further include: receiving a first query for using the first object included in the second database server from the first database server; extracting a target operation for the first object by parsing the first query; and determining whether the first query is to be executed by the second database server based on the first object, the target operation, and the access information.

The determining of whether the first query is to be executed by the second database server based on the first object, the target operation, and the access information may include determining whether the target operation is included in the at least one first operation based on the second information, and determining that the first query is not executed by the second database server when the target operation is not included in the at least one first operation.
The determining of whether the first query is to be executed by the second database server based on the first object, the target operation, and the access information may include determining whether the target operation is included in the at least one first operation based on the second information, and determining that the first query is executed by the second database server when the target operation is included in the at least one first operation.
The method may further include: receiving a result of performing the first query from the second database server; and delivering the result of performing the first query to the first database server.
The method may further include: re-writing the first query to include the first object corresponding to the virtual object based on information on the virtual object included in the first query when it is determined that the first query is executed by the second database server; and transmitting the re-written first query to the second database server so that the re-written first query is executed by the second database server.
The gateway server may include a reference object having a data structure of mapping the first object which exists in the second database server usable by the first database server and at least one first operation enabled to be performed by the first database server for the first object.
Disclosed is a gateway server for remotely managing a database, which may include: a communication unit receiving an access information registration request for accessing a second database server from a first database server; and a processor generating access information including first information for a first object usable by the first database server based on the access information registration request, the first object being positioned in the second database server, in which the communication unit may transmit a virtual object corresponding to the first object to the first database server based on the access information.
Disclosed is a computer program stored in a computer-readable storage medium in which when the computer program is executed by one or more processors, the computer program executes a method for remotely managing a database, and the method may include: receiving an access information registration request for accessing a second database server from a first database server; generating access information including first information for a first object usable by the first database server based on the access information registration request, the first object being positioned in the second database server; and transmitting a virtual object corresponding to the first object to the first database server based on the access information.

In the present disclosure a method for remotely managing a database may be performed by a gateway server. The gateway server may be a server providing an access between a first database server directly used by a user or accessed by the user and a second database server remotely positioned from the first database server. The gateway server may be a server that serves as a relay so that the user of the first database server uses an object included in the second database server. Alternatively, the gateway server may be a server that performs security or authentication so that the first database server uses an object positioned in the second database server. The object may mean a logical storage structure which exists in a database. As an example, the object may be a table in which one or multiple columns are gathered to constitute one record. As another example, the object may be a view which connects one or more tables, but does not store real data. As yet another example, the object may be an index for rapidly finding data in the table.
Hereinafter, a method for remotely managing a database performed by a gateway server according to the present disclosure will be described through
Referring to
The gateway server 100 may include a predetermined type of computer system or computer device such as a microprocessor, a mainframe computer, a digital processor, a portable device, and a device controller.
The processor 110 may control an overall operation of the gateway server 100. The processor 110 processes a signal, data, information, and the like input or output through the components of the gateway server 100 or drives the application program stored in the memory to provide or process appropriate information or function.
The processor 110 may be constituted by one or more cores and may include processors for data analysis, which include a central processing unit (CPU), a general purpose graphics processing unit (GPGPU), a tensor processing unit (TPU), and the like of the gateway server 100.
In the present disclosure, the processor 110 may generate access information based on an access information registration request received from a first database server 200 through the communication unit 130. The access information may be information for using a first object positioned in a second database server 300 by the first database server 200. The object may be, for example, a table in which one or multiple columns are gathered to constitute one record.
Specifically, the access information may include first information on a first object usable by the first database server 200 and second information on at least one first operation which the first database server 200 for the first object may perform.
For example, a plurality of objects may be stored in the second database server 300. The processor 110 may generate first information indicating that the first database server 200 may use the first object among the plurality of objects based on the access information registration request received from the first database server 200 through the communication unit 130.
The processor 110 may generate second information for at least one first operation which the first database server 200 may perform for the first object. For example, at least one first operation as an operation related to a data manipulation language (DML) may be an operation such as SELECT, INSERT, UPDATE, or DELETE. The processor 110 may generate second information for at least one first operation which the first database server 200 may perform among SELECT, INSERT, UPDATE, or DELETE. According to an exemplary embodiment, at least one first operation as an operation related to a data definition language (DDL) may be an operation such as CREATE, ALTER, DROP, or TRUNCATE. At least one first operation as an operation related to a data control language (DCL) may be an operation such as GRANT, REVOKE, COMMIT, ROLLBACK, etc. Hereinafter, an example for the method for generating the access information by the processor 110 will be described through

The storage unit 120 may include one or more memories including a buffer cache. Here, the memory as a primary storage device directly accessed by the processor 110, such as a random access memory (RAM) including a dynamic random access memory (DRAM), a static random access memory (SRAM), etc., may mean a volatile storage device in which stored information is momentarily erased when power is turned off, but is not limited thereto. The memory may be operated by the processor 110. The memory may include a buffer cache and data may be stored in a data block of the buffer cache. The data may be written in the storage unit 120 by a background process.
The storage unit 120 may store any type of information created or determined by the processor 110 or any type of information received by the communication unit 130. In the present disclosure, the storage unit 120 may store access information for using an object positioned in the second database server 300 by the first database server 200.
The communication unit 130 may include one or more modules which enable communication between the gateway server 100 and a communication system, between the gateway server 100 and the first database server 200, between the gateway server 100 and the second database server 300, or between the gateway server 100 and the network 400. The communication unit 130 may include at least one of a wired Internet module, and a wireless Internet module.
The gateway server 100 may further include a database management system (DBMS).
The DBMS as a program for permitting the gateway server 100 to perform operations including retrieval, insertion, modification, and/or deletion of required data may be implemented by the processor 110 in the memory.
The first database server 200 may include a predetermined type of computer system or computer device such as a microprocessor, a mainframe computer, a digital processor, a portable device, and a device controller. In the present disclosure, the first database server 200 may be a server used by the user. As an example, the first database server 200 may be the computing device or a local database server. As another example, the first database server 200 may be a database server which the user accesses through the computing device, etc.
The computing device may mean nodes in a database system having a mechanism for communication through a network 400. For example, the computing device may include a predetermined electronic device having connectivity with a personal computer (PC), a laptop computer, a workstation, a terminal, and/or the network. Further, the computing device may include a predetermined server implemented by at least one of agent, application programming interface (API), and plug-in.
According to some exemplary embodiments of the present disclosure, the gateway server 100 may also be a module included in the first database server 200. Alternatively, the first database server 200 may also include a computer program stored in a computer readable medium for implementing an operation performed by the gateway server 100 according to the present disclosure.
The second database server 300 may include a predetermined type of computer system or computer device such as a microprocessor, a mainframe computer, a digital processor, a portable device, and a device controller. In the present disclosure, the second database server 300 may be a server positioned remotely from the first database server 200. The second database server 300 may be a server at which at least one object the user of the first database server 200 intends to use is positioned.
The network 400 may be configured regardless of communication modes such as wired and wireless modes and constituted by various communication networks including a personal area network (PAN), a local area network (LAN), a wide area network (WAN), and the like. Further, the network may be known World Wide Web (WWW) and may adopt a wireless transmission technology used for short-distance communication, such as infrared data association (IrDA) or Bluetooth. The techniques described in this specification may also be used in other networks in addition to the aforementioned networks.
According to the above-described configuration, the gateway server 100 may generate the access information including the first information on the first object usable by the first database server 200 based on the access information registration request received from the first database server 200. The gateway server 100 may restrict the object usable by the first database server 200 based on the access information. For example, the gateway server 100 may generate access information so that the first database server 200 may use only the first object among the plurality of objects positioned in the second database server 300. Accordingly, the gateway server 100 may prevent the user of the first database server 200 from indiscreetly using the object positioned in the second database server 300. Further, the gateway server 100 may prevent the user of the first database server 200 from indiscreetly modifying or deleting the object positioned in the second database server 300.
Hereinafter, a method for remotely managing the database by the gateway server 100 will be described.
Referring to
In the present disclosure, the access information registration request which the communication unit 130 receives from the first database server 200 may not be a request for using a specific database server. In the present disclosure, the access information registration request which the communication unit 130 receives from the first database server 200 may be a request for using not the specific database server but at least one database server. As an example, the user of the first database server 200 may not know at which database server the first object to be used is positioned. Accordingly, the user of the first database server 200 may transmit the access information registration request for using at least one database server to the gateway server 100 through the first database server 200.
The processor 110 may generate the access information including the first information on the first object usable by the first database server 200 based on the access information registration request (S120). Here, the first object may be an object positioned in the second database server 300. In other words, the processor 110 may generate access information including first information representing at least one object usable by the first database server 200 among a plurality of objects positioned in the second database server 300 based on the access information registration request.
According to some exemplary embodiments of the present disclosure, the access information may include second information for at least one first operation which the first database server 200 may perform for the first object.
Specifically, at least one first operation as an operation related to a data manipulation language (DML) may be an operation such as SELECT, INSERT, UPDATE, or DELETE. The processor 110 may generate second information for at least one first operation which the first database server 200 may perform among SELECT, INSERT, UPDATE, or DELETE.
For example, the processor 110 may determine that the first database server 200 may use the first object among the plurality of objects positioned in the second database server 300 and generate the first information. The processor 110 may generate second information for determining that the first database server 200 is capable of performing the SELECT operation for the first object. The processor 110 may generate second information for determining that the first database server 200 is not capable of performing the DELETE operation for the first object. According to an exemplary embodiment, the processor 110 may store the first information and the second information in the storage unit 120 in a list type.
According to some exemplary embodiments of the present disclosure, the gateway server 100 may include a reference object having a data structure that maps the first object which exists in the second database server 300 usable by the first database server 200 and at least one first operation which the first database server 200 may perform for the first object. Here, the reference object may be an object representing a location of the first object in the second database server 300. In other words, the gateway server 100 may not actually store the first object, but may store the reference object representing the location of the first object in the storage unit 120.
The communication unit 130 may transmit a virtual object corresponding to the first object to the first database server 200 based on the access information (S130). The virtual object may be a new object for defining the first object positioned in the second database server 300 to be used in the first database server 200. The virtual object may be a virtual object not including actual data. In other words, even though the processor 110 determines that the first database server 200 may use the first object, the processor 110 may not directly transmit the first object to the first database server 200. The reason is that when the first database server 200 directly uses the first object, a problem may occur for another user who uses the second database server 300. When the virtual object is received, the first database server 200 may display the virtual object to the user.
According to some exemplary embodiments of the present disclosure, the definition of the virtual object corresponding to the first object may be stored in the first database server 200 in the list type. The first database server 200 may define the virtual object regardless of existence of the first object which the virtual object refers to. In other words, the first database server 200 may define the virtual object even for an object which does not actually exist. The first database server 200 may not delete the definition of the virtual object even though the actual object to which the virtual object refers is deleted. When the first database server 200 transmits a query for using the first object to the gateway server 100, the first database server 200 may transmit information on the corresponding virtual object instead of the object registered in the gateway server 100. In other words, the query may include the information on the virtual object corresponding to the first object.
According to the above-described configuration, as the gateway server 100 receives the access information registration request for using the second database server 300 from the first database server 200, the gateway server 100 may generate access information including first information and second information. The gateway server 100 may transmit the virtual object corresponding to the first object to the first database server 200 based on the access information. Accordingly, the gateway server 100 may restrict an object usable by the user of the first database server 200, and as a result, security for the object positioned in the second database server 300 may be enhanced.
Access information for using the object positioned in the second database server 300 by the first database server 200 may be stored only in the gateway server 100. In other words, the access information related to the second database server 300 by the first database server 200 may not be stored in the first database server 200, but stored only in the gateway server 100. Accordingly, a situation may be prevented in which the access information for accessing the second database server 300 is exposed in the first database server.
According to some exemplary embodiments of the present disclosure, the gateway server 100 may generate the access information to the first database server 200, and then receive the first query for using the first object included in the second database server 300 from the first database server 200. The gateway server 100 may determine whether the first query is to be executed in the second database server 300 based on the access information. Hereinafter, an example of the method for determining whether the first query is to be executed in the second database server 300 by the gateway server 100 according to the present disclosure will be described through
Referring to
The processor 110 may extract a target operation for the first object by parsing the first query (S220). The parsing may be generally an operation of checking a grammar of a query, whether there is an authority, checking whether there is a conventional query in a library cache, etc. In the present disclosure, the parsing may be appreciated as an operation of extracting an object which the first database server 200 intends to use and a target operation for the object through the first query. For example, the object which the first database server 200 intends to use may be the first object. When the first query is the query for selecting the first object, the target operation may be the SELECT operation for the first object. When the first query is the query for deleting the first object, the target operation may be the DELETE operation for the first object.
The processor 110 may determine whether the first query is to be executed in the second database server 300 based on the first object, the target operation and the access information (S230).
Specifically, the processor 110 may determine whether the target operation for the first object is an operation which may be performed by the first database server 200 based on second information.
For example, when it is determined that the target operation is included in at least one first operation based on the second information, the processor 110 may determine that the target operation is an operation which may be performed by the first database server 200. When it is determined that the target operation is the operation which may be performed by the first database server 200, the communication unit 130 transmits the first query to the second database server 300 to cause the first query to be executed by the second database server 300. When the second database server 300 executes the first query, the communication unit 130 may receive a result of performing the first query from the second database server 300. The communication unit 130 may deliver the result of performing the first query to the first database server 200.
As another example, when it is determined that the target operation is not included in at least one first operation based on the second information, the processor 110 may determine that the target operation is an operation which may not be performed by the first database server 200. When it is determined that the target operation is the operation which may not be performed by the first database server 200, the communication unit 130 may not transmit the first query to the second database server 300. According to an exemplary embodiment, when the target operation is the operation which may not be performed by the first database server 200, the processor 110 may return the first query. Here, a meaning of returning the first query may be appreciated as a meaning of not executing the first query. When the processor 110 returns the first query, information representing that a condition for executing the first query is not provided or information representing that the target operation included in the first query may not be performed by the first database server 200 may be generated, and transmitted to the first database server 200 through the communication unit 130.
According to the above-described configuration, the gateway server 100 may determine whether the first query is to be executed in the second database server 300 based on the first object, the target operation, and the access information when receiving the first query. When it is determined that the target operation is the operation which may be performed by the first database server 200, the gateway server 100 transmits the first query to the second database server 300 to cause the first query to be executed by the second database server 300. The gateway server 100 may receive the result of performing the first query from the second database server 300 and deliver the received result to the first database server 200. As a result, the user of the first database server 200 may recognize that the operation for the first object or the virtual object corresponding to the first object is performed only in the first database server 200. Accordingly, existence of the gateway server 100 and the second database server 300 may not be exposed to the user, and furthermore, the user may not also recognize in which database server the first object exists. In this case, the security for the plurality of objects positioned in the second database server 300 may be enhanced.
According to some exemplary embodiments of the present disclosure, the gateway server 100 may determine that the first query is executed by the second database server 300 based on whether the target operation being included in at least one first operation. Hereinafter, an example of a method in which the gateway server 100 causes the first query to be executed by the second database server 300 according to the present disclosure will be described through
Referring to
When the target operation is included in at least one first operation (S232, Yes), the processor 110 may determine that the first query is executed in the second database server 300 (S233). When it is determined that the first query is executed, the communication unit 130 transmits the first query to the second database server 300 to cause the first query to be executed by the second database server 300. When the second database server 300 executes the first query, the communication unit 130 may receive the result of performing the first query from the second database server 300. The communication unit 130 may deliver the result of performing the first query to the first database server 200.
When the target operation is not included in at least one first operation (S232, No), the processor 110 may determine that the first query is not executed in the second database server 300. When it is determined that the first query is not executed, the communication unit 130 may not transmit the first query to the second database server 300. According to an exemplary embodiment, when it is determined that the target operation is the operation which may not be performed by the first database server 200, the processor 110 may return the first query.
According to the above-described configuration, the gateway server 100 may transmit or not transmit the first query to the second database server 300 based on whether the target operation being included in at least one first operation. If the gateway server 100 transmits the first query to the second database server 300 without determining whether the target operation is included in at least one first operation, the second database server 300 may also execute the first query prepared by a user having no authority. In this case, at least one object may be modified or deleted by the user having no authority. Accordingly, the gateway server 100 may transmit or not transmit the first query to the second database server 300 based on whether the target operation being included in at least one first operation.
According to some exemplary embodiments of the present disclosure, the gateway server 100 may re-write the first query. As an example, the user of the first database server 200 may generate the first query by using the first object. Since the first object delivered to the first database server 200 in advance is actually the virtual object, the first query may be generated based on the virtual object. As a result, the first query may be a query generated by using the virtual object corresponding to the first object. On the contrary, the first object positioned in the second database server 300 may be a real object other than the virtual object. Accordingly, the gateway server 100 may re-write the first query so as for the second database server 300 to execute the first query. However, although not illustrated thereto, the first query may also include information on the first object corresponding to the virtual object. In other words, the first query may also be a query generated based on the first object corresponding to the virtual object. Hereinafter, an example of a method in which the gateway server 100 re-writes the first query according to the present disclosure will be described through

Specifically, the first query may be a query generated by using the virtual object corresponding to the first object. On the contrary, the first object positioned in the second database server 300 may be a real object other than the virtual object. Accordingly, the gateway server 100 may re-write the first query so as for the second database server 300 to execute the first query and make the first object be included in the first query.
The communication unit 130 may transmit the re-written first query to the second database server 300 so as for the second database server 300 to execute the re-written first query (S2332). As a result, the second database server 300 may perform the re-written first query and deliver a result of performing the re-written first query to the gateway server 100. The gateway server 100 may deliver the result received from the second database server 300 to the first database server 200.
According to the above-described configuration, the gateway server 100 may re-write the first query received from the first database server 200. Accordingly, even though the user generates the first query by using the virtual object corresponding to the first object, the first query may be executed by the second database server 300. As a result, the user may conveniently generate the query without recognizing whether a currently used object is the virtual object or the real object.
