Abstract
Abstract A version control system is described for use in connection with a database management system to facilitate versioning of a database table, the system including a database table and a version control module. The database table comprises a plurality of records, each record including at least one data field for storing user data and at least some of the records including a version control field including version control information. The version control module is configured to, in response to a user query related to the database table and related to a version, generate an augmented query for processing by the data base management system, the augmented query relating to the user query and the version control information. The version control module facilitates association of versions of the database with respective ones of a hierarchy of states and allows conflicts therebetween to be resolved, data to be posted from child states to respective parent states in the hierarchy, and referential constraints between tables to be preserved.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
79 words
A method for providing version control of a database, the method comprising: receiving a query specifying a modification to be performed on one of a plurality of records of the database; generating, based on the received query, an augmented query specifying a version of the one record and the manipulation to be performed on the version of the one record; and causing the augmented query to be processed thereby performing the manipulation on the version of the one record.
Claim 2
Independent Claim
79 words
A method for providing version control of a database, the method comprising: receiving a query specifying a modification to be performed on one of a plurality of records of the database; generating, based on the received query, an augmented query specifying a version of the one record and the manipulation to be performed on the version of the one record; and causing the augmented query to be processed thereby performing the manipulation on the version of the one record.
Claim 3
Dependent Claim
17 words
A method of according to claim 1 , wherein the includes one of modification, addition, and deletion.
Claim 4
Dependent Claim
55 words
A method of according to claim 1 , wherein the records are associated with respective versions, each of the records includes: a version identifier field for storing the version of the respective record; and a next version identifier field for storing at least one of another version of the respective record and a default value.
Claim 5
Dependent Claim
30 words
A method according to claim 3 , wherein the version identifier fields and the next version identifier fields effect a tree structure of nodes representing corresponding versions of the records.
Claim 6
Dependent Claim
42 words
A method according to claim 3 , further comprising: determining whether the version of the one record exists; and instructing establishment of a new record based upon the determining step, the new record including a field for specifying a corresponding version identifier.
Claim 7
Dependent Claim
49 words

Claim 8
Dependent Claim
32 words
A method according to claim 1 , further comprising: storing identification information associated with the version of the one record to define a state among a plurality of states of the database.

Dependent Claim
32 words
A method according to claim 1 , wherein the one record has multiple versions, the method further comprising: providing access to a pre-designated version of the versions in response to the query.
Claim 11
Dependent Claim
34 words
A method according to claim 1 , wherein the one record has multiple versions, the method further comprising: identifying the version among a plurality of versions of the one record to satisfy the query.
Claim 12
Dependent Claim
36 words
A method according to claim 1 , wherein the database includes a plurality of tables containing the records, the further comprising: specifying on a table-by-table basis whether more than one version of the records can exist.
Claim 13
Dependent Claim
32 words
A computer-readable medium bearing instructions for providing version control of a database, said instruction, being arranged, upon execution, to cause one or more processors to perform the method of claim 1 .
Claim 14
Independent Claim
85 words
A system for providing version control of a database, the system comprising: means for receiving a query specifying a modification to be performed on one of a plurality of records of the database; means for generating, based on the received query, an augmented query specifying a version of the one record and the manipulation to be performed on the version of the one record; and means for causing the augmented query to be processed thereby performing the manipulation on the version of the one record.
Claim 15
Independent Claim
85 words
A system for providing version control of a database, the system comprising: means for receiving a query specifying a modification to be performed on one of a plurality of records of the database; means for generating, based on the received query, an augmented query specifying a version of the one record and the manipulation to be performed on the version of the one record; and means for causing the augmented query to be processed thereby performing the manipulation on the version of the one record.
