This paper focused on the formal description of data warehouse security requirements. Security requirements for data warehouse were presented. Based on multidimensional expressions (MDX), a multidimensional security constraint language (MDSCL) was defined to describe the security strategy of data warehouse by syntax similar to the CREATE CUBE statement in Microsoft SOL SERVER database. This approach makes the language readable for system administrators and designers, or end-users. Taken a typical scales cube as an example several safety constraint type supported by multi-dimentional safety constraint type were given. The security model represented by MDSCL accorded with the open nature, of data warehouses and can describe most of security requirements in data warehouse in practice.
