Abstract
A system and method that enables quick access to large volumes of data on a realtime basis and is totally transparent to application programs that use the data. This is accomplished by placing information extracted from the database into a master file stored in a data storage device and then loaded into memory for access by application programs. When information in the database changes the corresponding information is updated using an incremental file and an index file that are then loaded into memory for access by application programs. The master file, index file and incremental file are linked in such as fashion to enable quick access to data desired.
