ABSTRACT:
The invention provides a system and method of retrieving data associated with a file from a database by a field name into local memory. It comprises calculating an address reference for a storage location in the local memory for the data; fetching the data from the database; and utilizing the address reference to map the data to an address in the local memory. The address reference is an offset value from a base address of the storage location. Several files may be accessed using a cross reference table containing pointers to field tables. Entries in the cross reference table point to a field table. Each field table is a list of fields associated with the file. Each entry in the field table is a calculated offset value providing an address offset of a particular field from the base address of the file.
