CELL-BASED SECURITY REPRESENTATION FOR DATA ACCESS

The invention discloses an architecture for cell-based security on a per-user basis. A security model for this capability includes not only dimension level tables, but is extended to include cell level tables. The security model can include existing dimension tables, plus cell security tables that include a cell permissions table, a cell qualifiers table and a table that includes both the cell permissions table, a cell qualifiers. Metadata associated with the security applied to the cells for a given user can be stored locally in a local metadata store for retrieval and application against a data cube that an authenticated and authorized user is querying.; In a specific implementation, the cell level security is employed in a performance management server application, where authentication is performed remotely by an authentication service, but the authorization function is performed local to the performance management server application. 描述了种用于在每个用户的基础上的基于单元格的安全性的体系结构。用于该能力的安全模型不仅包括维度级表，而且被扩展成包括单元格级表。该安全模型可包括
