Abstract
A data access system of the present invention includes an interface (client), a data engine having a common application programming interface layer, and data drivers. Through the drivers, the data engine (responding to client requests) accesses foreign data objects, which may include information tables, files, and other data objects of a foreign format. In this manner, the system provides a virtual interface between a client (e.g., database manager) and individual foreign data objects (e.g., database files). Regardless of the format of the individual database files, all files can be shared without the need to make copies.
