FIELD OF THE INVENTION

Some embodiments may relate to computer game data and other game or user associated data in an online environment. Some embodiments may relate to computer devices connected in a communications network with at least one database storing said data. The computer devices may be configured to selectively communicate with each other over the network. Some embodiments may relate to management and update of the at least one database.

BACKGROUND OF THE INVENTION

Some computer implemented games may have a very large number of players, each having associated data such as identity (user-name), email, scores, time played, and other associated data which may be provided by the user, for example social network accounts and associated friends therein. Managing such data in databases can present complex infrastructure challenges. This is particularly so when the number of users or players numbers in the tens or hundreds of millions at any one time. Updating user or player data, and mining such “Big Data” is another technical challenge.

Extending a database, by for example adding new fields, typically involves “downtime” in the back-end infrastructure to update the database. Populating the new fields with record data may also involve “downtime”, and in any event the record data for the new field(s) may not be available at the time the database is extended.

FIG. 2 schematically shows a system 200 in some embodiments. The system 200 comprises a server 220 which may store or be in communication with databases 250 which may be, in some embodiments, connected to a back end infrastructure 240 “BEN”) of game player's details, profiles, statistics, etc. In practice, one or more databases 250 may be provided. Where more than one server 220 is provided, the database(s) 250 may be provided in one database 250 or across two or more servers 220, 310. The server 220 may also have a games data function. This may comprise one or more units of memory to store the computer game program and user behaviour data, and a processor to run the games program and process the user behaviour data.

The server 220 may communicate via for instance the internet 210 to one or more user devices 100, shown in the figure by way of example as user devices 100a, 100b and 100c, and may further provide connections to a social network 230 such as facebook™.

FIG. 3 illustrates a back end infrastructure 300 according to an embodiment, comprising a server 310 in communication with or connected to a control module 320. The control module 320 may be implemented 340 as part of server 310, or may be a separate module 320 external to and connected with the server 310. The server 310 may be one of many servers, such as those known to the person skilled in the art as a server farm 340, or rack

The server 310 or farm 340 may be connected as shown to server 220, and to database 250 via link 330. Link 330 may be wired, wireless and/or provided via or through networks such as the internet, as known to those persons skilled in the art. The control module 320 provides control and update of data in the database(s) 250 as will now be described with reference to FIGS. 4A, 4B and FIG. 5.

FIG. 4A illustrates an example table or array of data stored in database(s) 250. The data is shown as a table or array for ease of understanding, but of course those skilled in the art will realise that other data structures typical of relational databases may be employed, for example multi-dimensional arrays may be utilised. In general, FIG. 4A shows data stored before extension of the database, whilst FIG. 4B shows data stored after extension of the database according to an embodiment.

FIG. 4A shows data 400 arranged in columns or fields 420. The data may comprise user names, associated high score, social network name and so on of players or users accessing and playing the computer implemented game, such as applicants game “Candy Crush Saga”™.

In fact, it is noted that, according to the BBC as of December 2013, “150 billion games of Candy Crush Saga have been played to date. 500 million people have installed Candy Crush” (see http://www.bbc.co.uk/news/magazine-25334716).

Another source, the UK newspaper the Guardian, commented in March 2014 that “93m people are playing Candy Crush Saga more than 1 billion times a day.” (see http://www.theguardian.com/technology/2014/mar/26/candy-crush-saga-king-why-popular).

Hence, these numbers alone have provided severe issues and problems for the applicant or hosts of the applicants' servers and databases, regarding the management, control and updating of such.

Returning now to FIG. 4, FIG. 4B shows an example of a table or array of data stored in a database(s) 250, after extension. FIG. 4B shows a table 400 comprising columns or fields 420, each containing data 400. FIG. 4B also shows the database in an extended mode since new column or field 440 has been added to the database 250. New column or field 440 comprises data where available 450, or no value data 460 as shown in the figure.

The addition of the new field or column 440 and population of the new column or field 440 will now be described with reference to FIG. 5 and FIG. 6.

FIG. 5 shows, in an embodiment, a control module 320. The control module may comprise at least one processor 510, linked to a memory 520, as shown in the diagram. The at least one memory 520 may store at least one predetermined rule 530a, and at least one further rule 530b. Other rules may be stored in some embodiments 530c.

In an embodiment the control module 320 may be part of a server 310, 220. In an embodiment control module 320 may be a separate computing device forming part of the back end 300.

In an embodiment rule 530a comprises the addition of a field or column 440 extending the database 250. Rule 530b comprises inserting a null indicator into a record 460 of new field 440 when no data exists.

In an embodiment, rule 530c may comprise monitoring database 250 in response to data provided by server 220 for an update to field 460 periodically.

FIG. 6 will now be described which defines a flowchart of an embodiment. At step 610, rules for the new field are defined and stored in memory 520. The rules may be, as in the previous embodiment rule 1, 530a, rule 2, 530b, and rule 3, 530c as previously described. In other embodiments, other rules may be predetermined. Control module 320 may then receive a request to add a new field 440 at step 620. The new field 440 is added to extend the at least one database 250 in accordance with at least one predetermined rule 530a stored in said at least one memory 520. The control module then proceeds to automatically populate or update records 460, 450 in the new field 440 in accordance with the defined rules 530a, 520b, 630c. Once the database 250 has been extended, the process then flows to this step 640 where control module 320, 510 monitors for a record update in the new field. Should an update occur, flow proceeds via path 650 to step 660 wherein an update of the record in the field occurs in accordance with defined rules, for example rule 530b. Control module 320 then returns via path 670 to step 640 to monitor the extended database field 440 for record updates.

In some embodiments, data where available is provided upon extension of the database. For example, data for the new field 440 may be provided 450 upon creation of the new field 440. Should data for a record in the new field not exist, then −a null value indicator or “no value” 460 is inserted to maintain the integrity of the database 250.

In some embodiments the “null value indicator” may comprise the numeral zero. In other embodiments, the null indicator may comprise a null text string, should the field records require text strings or ASCII.

The method described above allows an extension of an already large database 250 with a new field 440 containing or comprising individual records 450, 460, regardless of whether data 460 to fill the records is available at the time of the extension.

This has advantages in that, for relational databases, fields may be added unlinked to other existing fields 420 regardless of whether the actual record data 450 is available at the time of the extension.

The person skilled in the art will realise that the different approaches to implementing the methods and control module are not exhaustive, and what is described herein are certain embodiments. It is possible to implement the above in a number of variations without departing from the spirit or scope of the invention.
