| Number | Title | Issue Date |
| 4912637 | Version management tool A system for preserving, generating, and merging different versions of a common module that utilizes a line file storing the text of every line in a version and addressing each line with a unique line identifier. Any desired version may be generated direc... | 03/27/1990 |
| 4907191 | Data processing apparatus and data processing method A data processing method uses a file which has sequentially arranged records each having a data area for designating the number of measurements for each object or target to be measured, a data area provided for each of a plurality of pre-set measurement i... | 03/06/1990 |
| 4875159 | Version management system using plural control fields for synchronizing two versions of files in a multiprocessor system In a data processing system that stores a first and second version of a given data set, a method for synchronizing the first and second versions comprises steps of maintaining a sync-complete control field and a sync-in-progress control field in the inode... | 10/17/1989 |
| 4853843 | System for merging virtual partitions of a distributed database An object-oriented, distributed data base system separates into a plurality of virtual partitions following communication failure between sites accessing the data base. Each partition accesses a separate copy of an initial data base and independently upda... | 08/01/1989 |
| 4809170 | Computer device for aiding in the development of software system A support system for Computer-Aided Software Engineer (CASE) applications provides configuration management and features such as transparent retrieval of named versions of program sequences on a line by line basis as well as task monitoring and reporting.... | 02/28/1989 |
| 4807182 | Apparatus and method for comparing data groups Method and apparatus for comparing original and modified versions of a document. The system of the present invention utilizes a hash number generator CPU to generate hash numbers for lines and sentences contained in the documents. Matching hash numbers ar... | 02/21/1989 |
| 4800485 | On-line documentation facility Users of an on-line documentation facility in a computer system are provided with the capability of specifying modifications to be made to the documentation that would otherwise be provided by the system.... | 01/24/1989 |
| 4714996 | Impact calculation for version management in a distributed information service In a distributed processing system having a source node accessing data objects from a database and a replica node storing replicas of requested source data objects received from the source location, the impact to replicas caused by a change in a source da... | 12/22/1987 |
| 4714992 | Communication for version management in a distributed information service In a distributed processing system network in which at least one node operates as a source location having access to data objects of a database, and at least one other node operates as a replica location storing replicas of data objects from the source lo... | 12/22/1987 |
| 4648036 | Method for controlling query and update processing in a database system A method of performing update transactions in a database system to perserve consistent logical data states at all times. Each changeable data entry in the database is associated with an individual code field. When no update transaction is in progress, eve... | 03/03/1987 |
| 4646229 | Time-ordered data base A data base system includes future versions of the data base which are maintained currently in response to orders for future execution. All transactions against the data base are time stamped to assure access to the proper version of the data base. Inform... | 02/24/1987 |
| 4627019 | Database management system for controlling concurrent access to a database A method of assuring that each of a plurality of contemporaneously active database transactions comprising at least one read transaction and at most one update transaction has a consistent view of a database storing a plurality of versions of a relation. ... | 12/02/1986 |
| 4558413 | Software version management system A software version management system, also called system modeller, provides for automatically collecting and recompiling updated versions of component software objects comprising a software program for operation on a plurality of personal computers couple... | 12/10/1985 |
