Abstract

A system for interfacing application programs with a database. The system preferably comprises at least one application program adapted to communicate with a first database type, a database of a second database type, and a layering application program in communication between the application program and the database of a second database type. Preferably, the layering application program is for facilitating communication between the application program and the database of a second database type. The application program is adapted to access data in a database of the first database type using first database access commands adapted for communication with the first database type. In addition, the database of a second database type preferably is accessed by application programs using second database access commands adapted for communication with the second database type. The layering application program preferably converts the first database access commands from the application program to the second database access commands, so that the application program can access data in said database of the second database type. In addition, layering application programs can be used to convert data from a first database format to a second database format.
