  • Patent number: 7953714
    Abstract: In one implementation, a method for sustaining database processing parallelism of one or more parallelized processes to build one or more index pages using pseudo record identifiers (PRIDs) is disclosed. The method comprises generating one or more PRIDs for one or more respective internal record formats (IRFs), inserting said generated PRIDs into a respective index key, generating a relational index of the PRID and a predetermined record identifier (RID) respectively determined in relation to said IRF, and building one or more index pages in relation to the relational index by comparing said RID and said PRID for their respective IRF in said relational index, and determining which one of said RID or said PRID to insert into said index page.

  • Publication number: 20100036671
    Abstract: A method and system for real time tracking and approving Federal Family Medical Leave Act (FMLA) leave requests is provided. Custom database objects are retrieved and processed, through a secure intranet JavaScript®1 interface, in real time to provide an employer with employee data associated with the FMLA. The system enables accurate approval or denial of FMLA leave requests for FMLA compliance. The variables for leave expenditures and accruals can be customized to meet the needs of a specific organization.
