Abstract
Paging of data includes querying a table of data to determine an item identifier for each item in the table. An index table including an index identifier column of sequential integers and a corresponding item identifier column for each item in the table is generated and stored in a memory. A page index table including the item identifier that corresponds to a first index identifier and each item identifier that corresponds to one plus a pagesize multiple of the index identifier is generated and stored in a memory. A desired page of data is retrieved using the determined item identifier corresponding to the first item on the desired page and either the determined item identifier corresponding to the first item on a next page after the desired page or a determined item identifier corresponding to the last item on the desired page.
