摘要:
A preferred system for providing data access comprises an application program interface configured to delegate a request to at least one service providers also included in the system. The service providers may include a synchronization manager configured to maintain, based upon the request, data consistency between a first server containing the service providers and a second server and a cache manager configured to cache, based upon the request, a portion of a database query. In addition, the service providers may include a pre-fetch service configured to anticipate a database query, perform the anticipated query, and cache the results of the anticipated query, and a security manager configured to determine a restriction on the request based upon a role of a user associated with the request.
