  • Implementing versioning support for data using a two-table approach that maximizes database efficiency
    Patent number: 8010887
    Abstract: A method, system, and storage medium for providing versioning of data by associating a version number having a value with a data item, establishing a table for storing a most recent version of the data item, establishing a second table for storing all versions of the data item other than the most recent version, storing the current version of the data item in the first table, storing all other versions of the data item in the second table, and determining the version of said database data item based on the version number and storage location of the database data item.
    Type: Grant

  • Utility for cross platform database query
    Patent number: 6643649
    Abstract: The present invention provides a utility for cross platform database query. In a preferred embodiment, the utility resides at an object server in a data system. The utility obtains a set of data items from a library server in the data system; places the set of data items from the library server in a temporary table at the object server; obtains each data item from the temporary table and the base object table; and converts each data item from the temporary table and the base object table, if a conversion is required, such that each data item from the temporary table and the base object table may be compared. Because the utility, the temporary table, and the base object table all reside at the same server, the utility knows whether or not to convert the data items so that a conflict free comparison is performed. In this manner, the utility need not actually know what platform is used by the library server, yet, data at the library server and the object server can be properly compared.
