Description
BACKGROUND

This specification relates to data processing systems implemented on computers, and, more particularly, to data processing systems providing services in the nature of web services.


Enterprise software systems are generally large and complex. Such systems can require many different components, distributed across many different hardware platforms, possibly in several different geographical locations. Thus, the architecture of a large software application, i.e., what its components are and how they fit together, is an important aspect of its design for a successful implementation.


Web services are one technology for making the functionality of software applications available to other software, including other applications. A web service is a standard-based way of encapsulating the functionality of an application that other applications can locate and access. A service-oriented architecture is a distributed software model within which all functionality is defined as independent web services. Within a service-oriented architecture, web services can be used in defined sequences according to the business logic to form applications that enable business processes.


SUMMARY

This specification describes a services architecture design that provides enterprise services having project management functionality at the level of an enterprise application. Enterprise services are web services that have an enterprise-level business value.


In its various aspects, the invention can be embodied in systems, methods, and computer program products. For example, a system in one embodiment implements a services architecture design that provides enterprise services having project management functionality at the level of an enterprise application. The design may include a set of service operations, process components, and optionally deployment units. Suitable business objects are also described.


The subject matter described in this specification can be implemented to realize one or more of the following advantages. Effective use is made of process components as units of software reuse, to provide a design that can be implemented reliably in a cost effective way. Effective use is made of deployment units, each of which is deployable on a separate computer hardware platform independent of every other deployment unit, to provide a scalable design. Service interfaces of the process components define a pair-wise interaction between pairs of process components that are in different deployment units in a scalable way.


Details of one or more implementations of the subject matter described in this specification are set forth in the accompanying drawings and in the description below. Further features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.

DETAILED DESCRIPTION


FIGS. 1A and 1B collectively illustrate a high-level view of a software architectural design and of an application software implementation that provides a suite of enterprise service operations, which can be organized into interfaces, having project management application functionality. The software corresponding to FIGS. 1A and 1B, in one implementation, is for deployment in an application layer of an application server.


The elements of the architecture include the business object, the process component, the service operation (or simply, the operation), the service interface, the message, and the deployment unit. The elements can also include process agents and reuse service components. These will be generally described below.


In some implementations, the software can be deployed on an application platform that includes a foundation layer that contains substantially all fundamental entities that can be used from multiple deployment units. These entities can be process components, business objects and/or reuse service components. A reuse service component may be a piece of software that is reused in different transactions. A reuse service component may be used by its defined interfaces, which can be, e.g., local APIs (Application Programming Interfaces) and/or service interfaces.


The architectural design may be a specification of a computer software application, and elements of the architectural design may be implemented to realize a software application that implements enterprise application service interfaces. The elements of the architecture are at times described in this specification as being contained or included in other elements; for example, a process component is described as being contained in a deployment unit. It should be understood, however, that such operational inclusion can be realized in a variety of ways and is not limited to a physical inclusion of the entirety of one element in another.


The architectural elements may include business objects. A business object may be a representation of a type of a uniquely identifiable business entity (an object instance) described by a structural model. Processes may operate on business objects.


A business object represents a specific view on some well-defined business content. A business object represents content, and instances of business objects include content, which a typical business user would expect and understand with little explanation. Whether an object as a type or an instance of an object is intended by the term is generally clear from the context, so the distinction will be made explicitly only when necessary. Properly implemented, business objects may be implemented free of redundancies.


Business objects may be further categorized as business process objects and master data objects. A business object may be an object that encapsulates master data (i.e., data that is valid for a period of time). A business process object, which is often the kind of business object generally found in a process component, may be an object that encapsulates transactional data, i.e., data that is valid for a point in time. A mass data run object may be an application object that executes an algorithm for a particular mass data run. An instance of a mass data run object may contain a particular set of selections and parameters. A mass data run object may implement an algorithm that modifies, manages, and/or processes a large amount of data in multiple transactions, possibly but not necessarily with parallel processing. A dependent object may be a business object used as a reuse part in another business object. A dependent object may represent a concept that cannot stand by itself from a business point of view. Instances of dependent objects can, in some implementations, only occur in the context of a non-dependent business object. A transformed object may be a transformation of multiple business objects for a well-defined purpose. It may transform the structure of multiple business objects into a common structure. In some implementations, the transformed object does not have its own persistency.


The architectural elements may also include the process component. A process component may include a software package that realizes a business process and generally exposes its functionality as services. The functionality may contain business transactions. A process component may contain one or more semantically related business objects. Any business object may belong to no more than one process component.


Process components may be modular and context-independent. That they are context-independent means that a process component may be not specific to any specific application and may be reusable. The process component may be the smallest (most granular) element of reuse in the architecture.


The architectural elements may also include the operation. An operation may belong to exactly one process component. A process component generally has multiple operations. Operations may be synchronous or asynchronous, corresponding to synchronous or asynchronous process agents, which will be described below. An operation may be the smallest, separately-callable function, described by a set of data types used as input, output, and fault parameters, or some combination of them serving as a signature. For convenience in supporting use of the operations supported by a system implementing elements of the design, such a system can optionally include a repository of service descriptions that includes a standards-based description of each of the supported service operations.


The architectural elements may also include the service interface, which may be referred to simply as an interface. An interface may be a named group of operations. Each operation may belong to exactly one interface. An interface may belong to exactly one process component. A process component might contain multiple interfaces. In some implementation, an interface can contain only inbound or outbound operations, but not a mixture of both. One interface may contain both synchronous and asynchronous operations. All operations of the same type (either inbound or outbound) which belong to the same message choreography may belong to the same interface. Thus, generally, all outbound operations to the same other process component may be in one interface.


The architectural elements may also include the message. Operations may transmit and receive messages. Any convenient messaging infrastructure may be used. A message may be information conveyed from one process component instance to another, with the expectation that activity will ensue. An operation may use multiple message types for inbound, outbound, and/or error messages. When two process components are in different deployment units, invocation of an operation of one process component by the other process component may be accomplished by an operation on the other process component sending a message to the first process component.


The architectural elements may also include the process agent. Process agents may do business processing that involves the sending or receiving of messages. Each operation frequently has at least one associated process agent. A process agent may be associated with one or more operations. Process agents may be either inbound or outbound, and either synchronous or asynchronous.


Asynchronous outbound process agents may be called after a business object changes, e.g., after a create, update, or delete of a business object instance.


Synchronous outbound process agents may be generally triggered directly by a business object.


An output process agent may generally perform some processing of the data of the business object instance whose change triggered the event. An outbound agent may trigger subsequent business process steps by sending messages using well-defined outbound services to another process component, which may be in another deployment unit, or to an external system. An outbound process agent may be linked to the one business object that triggers the agent, but it may be sent not to another business object but rather to another process component. Thus, the outbound process agent may be implemented without knowledge of the exact business object design of the recipient process component.


Inbound process agents may be called after a message has been received. Inbound process agents may be used for the inbound part of a message-based communication. An inbound process agent may start the execution of the business process step requested in a message by creating or updating one or multiple business object instances. An inbound process agent may not be the agent of a business object but of its process component. An inbound process agent may act on multiple business objects in a process component.


Synchronous agents may be used when a process component requires a more or less immediate response from another process component, and is waiting for that response to continue its work.


Operations and process components may be described in this specification in terms of process agents. However, in alternative implementations, process components and operations may be implemented without use of agents using other conventional techniques to perform the functions described in this specification.


The architectural elements may also include the deployment unit. A deployment unit may include one or more process components and, optionally, one or more business objects, that may be deployed together on a single computer system platform. Conversely, separate deployment units may be deployed on separate physical computing systems. For this reason, a deployment unit boundary may define the limits of an application-defined transaction, i.e., a set of actions that have the ACID properties of atomicity, consistency, isolation, and durability. To make use of database manager facilities, the architecture may require that all operations of such a transaction be performed on one physical database; as a consequence, the processes of such a transaction may be performed by the process components of one instance of one deployment unit.


The process components of one deployment unit may interact with those of another deployment unit using messages passed through one or more data communication networks or other suitable communication channels. Thus, a deployment unit deployed on a platform belonging one business may interact with a deployment unit software entity deployed on a separate platform belonging to a different and unrelated business, allowing for business-to-business communication. More than one instance of a given deployment unit may execute at the same time, on the same computing system or on separate physical computing systems. This arrangement may allow the functionality offered by a deployment unit to be scaled to meet demand by creating as many instances as needed.


Since interaction between deployment units may be through service operations, a deployment unit may be replaced by other another deployment unit as long as the new deployment unit supports the operations depended upon by other deployment units. Thus, while deployment units may depend on the external interfaces of process components in other deployment units, deployment units may not depend on process component interactions, i.e., interactions between process components involving their respective business objects, operations, interfaces, and messages within other deployment units. Similarly, process components that interact with other process components or external systems only through messages, e.g., as sent and received by operations, may also be replaced as long as the replacement supports the operations of the original.


Interactions between process components that occur only within a deployment unit may not constrained to using service operations. These may be implemented in any convenient fashion.


In contrast to a deployment unit, the foundation layer may not define a limit for application-defined transactions. Deployment units may communicate directly with entities in the foundation layer, which communication is typically not message based. The foundation layer may be active in every system instance on which the application is deployed. Business objects in the foundation layer may be master data objects. In addition, the foundation layer may include some business process objects that are used by multiple deployment units. Master data objects and business process objects that should be specific to a deployment unit may be assigned to their respective deployment unit.

As shown in FIG. 3, multiple outbound process agents may receive information from the Customer Project Invoicing Requisition business object 132.


An asynchronous outbound process agent 326 may invoke a Request Invoicing operation 328. For example, the operation 328 may send a send a request to create a customer invoice request or to update a customer invoice request previously created to the Customer Invoice Processing process component 304. The Request Invoicing operation 328 is included in a Request Invoicing Out interface 330.


The Customer Project Expense List business object 128 may receive updated information and send the update into other components to perform further operations. As shown in FIG. 3, multiple outbound process agents may receive information from the Customer Project Expense List business object 128.

FIG. 4 is a block diagram showing the Engineering Change Processing process component 152 (FIG. 1B). For convenience in describing this process component, an additional process component is shown in the figure; this additional process component may not be part of the process component being described. This other process component is the Data Migration System process component 204. The Data Migration System process component 204 may be used to represent software external to the process component in describing its interactions with the external software; however, while the external software can be implemented as such process component, this is not required.

The product requirement specification processing process component 156 includes the Product Requirement Specification business object 158. The Product Requirement Specification business object 158 represents a collection of requirements for a product used in a specific business context, for example, in a prototype, development project, or sales order. The business object 158 can also contain the corresponding specifications for fulfilling these requirements.


The subject matter described in this specification and all of the functional operations described in this specification can be implemented in digital electronic circuitry, or in computer software, firmware, or hardware, including the structural means disclosed in this specification and structural equivalents thereof, or in combinations of them. The subject matter described in this specification can be implemented as one or more computer program products, i.e., one or more computer programs tangibly embodied in an information carrier, e.g., in a machine-readable storage device or in a propagated signal, for execution by, or to control the operation of, data processing apparatus, e.g., a programmable processor, a computer, or multiple computers. A computer program (also known as a program, software, software application, or code) can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program does not necessarily correspond to a file. A program can be stored in a portion of a file that holds other programs or data, in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub-programs, or portions of code). A computer program can be deployed to be executed on one computer or on multiple computers at one site or distributed across multiple sites and interconnected by a communication network.


The processes and logic flows described in this specification can be performed by one or more programmable processors executing one or more computer programs to perform functions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application-specific integrated circuit).


Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read-only memory or a random access memory or both. The essential elements of a computer are a processor for executing instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto-optical disks, or optical disks. Information carriers suitable for embodying computer program instructions and data include all forms of non-volatile memory, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.


To provide for interaction with a user, the subject matter described in this specification can be implemented on a computer having a display device, e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor, for displaying information to the user and a keyboard and a pointing device, e.g., a mouse or a trackball, by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback, e.g., visual feedback, auditory feedback, or tactile feedback; and input from the user can be received in any form, including acoustic, speech, or tactile input.
