OPTIMIZING A DATA CACHE WHEN APPLYING USER-BASED SECURITY

摘要

A secure caching system and caching method include receiving a user request for data, the request containing a security context, wherein the security context identifies the user's security profile of the database application, and searching a cache for the requested data based on the user request and the received security context. If the requested data is found in cache, returning the cached data in response to the user request. If the requested data is not found in cache, obtaining the requested data from a data source, storing the obtained data in the cache and associating the obtained data with the security context, and returning the requested data in response to the user request. The search for the requested data can include searching for a security list that has the security context as a key, the security list including an address in the cache of the requested data.
