Abstract
A method and apparatus for improving the efficiency and security of a database management system (DBMS) is disclosed. A plurality of query packages are stored at a host DBMS. Generation of the query packages is limited only to those users that have authorization, such as the database administrator of the DBMS. The query packages include a plurality of procedures. Each procedure is a single SQL statement that has been pre-compiled. Each query package also includes an authorization table that enumerates each individual user, or category of user, that can invoke any procedure within the query package. By formulating a plurality of query packages, each package tailored to a particular category of user, security of the data on the DBMS is enhanced. Further, by having static statements that are pre-compiled, access time to the data on the DBMS is significantly reduced. Moreover, the database administrator and users can interactively generate and use the query packages in a user friendly environment.
