  • Patent number: 6240414
    Abstract: A method and system for automatically resolving data conflicts in a shared data environment where a plurality of users can concurrently access at least portions of a master data file is presented. Users process data files by means of local copies of a master data file. When an attempted update of a master data file with an edited data file from a user is detected, the updating file is analyzed to determine if any changes made are in conflict with changes made to the master data file by a second user. If a conflict is detected, it is resolved by merging the updating file into the master file according to a predefined set of rules. For conflicts which are not resolved by rule-based reconciliation, at least one user is notified of the conflict and presented with conflict resolving information and the conflict is resolved according to user input.

  • Patent number: 6212511
    Abstract: An access control database defines access rights through the use of access control objects. The access control objects include group objects, each defining a group and a set of users who are members of the group, and rule objects. A first subset of the rule objects each specify a set of the group objects, a set of the management objects, and access rights by the users who are members of the groups defined by the specified set of the group objects to the specified set of management objects. The access control server responds to the access requests from the users by granting, denying and partially granting and denying the access requested in each access request in accordance with the access rights specified in the access control database. A database management system receives management information from the network and stores that information in a set of database tables.

  • Patent number: 6212526
    Abstract: Method and apparatus for the construction of a classification model (for example a decision tree) from data in a large database. The database is stored in the form of data records on a storage medium for access by a computer. The computer executes a software component for building a classification model from the data in the database. The classification building component has a scheduler that directs the computer to sequentially access all records in the database one or more times as required for extracting the necessary sufficient statistics to construct the classification model. The method optimizes the construction of the classifier from the database by minimizing the number of database scans and making as much use of the computer's fast main memory (RAM) as possible. The method prescribes three different modes for scanning data and includes a scheduler component that decides which of these modes to employ and on what parts of the database.

  • Patent number: 6212524
    Abstract: A method of generating a datamart is described. The datamart includes tables having rows and columns. The method comprises accessing a description of a schema. The schema defines the relationships between the tables and columns. The description further defines how data is to be manipulated and used to populate the tables in the datamart. That is, the description defines the semantic meaning of the data. The description is further used to create a set of commands to create the tables. The commands are executed causing the creation of the tables. Importantly, when the semantic meaning is associated with the column and rows, programs for manipulating and propagating data into those columns and rows are automatically defined. Previously, consultants would have to hand code the creation, manipulation, and population programs for a datamart. Thus, the amount of work required to create and populate the datamart is significantly reduced.
