Abstract

A method and system for managing a computer system are described. The method and system include defining and storing a policy using a policy manager. In one aspect, the policy manager also activates and resolves conflicts between policies. The policy is a declarative statement of a directive to be carried out by the computer system. The method and system also include using a policy executor to determine whether a request to the computer system is covered by the policy. The method and system further include utilizing the computer system to carry out the directive for the policy if the request is covered by the policy through a policy enforcer.

Description

technical field [0001] The present methods and systems relate to data storage and retrieval systems, and more particularly, to managing the activities of database systems through the use of policies. Background technique [0002] Database systems are increasingly used to store, organize and access data. FIG. 1 depicts a conventional database system 10 . For brevity, only portions of database system 10 are shown. Database system 10 generally includes at least one user interface (UI) 12 , database engine 14 , and storage subsystem 16 . Through the UI 12, the user 19 may enter queries, statements, or database requests in the database's native query language to access, add to, and / or alter desired portions of the data stored in the storage subsystem 16 . Similarly, applications 18 may also provide database requests to database system 10 to access, add to, and / or alter desired portions of data stored in storage subsystem 16 . Typically, such queries are performed by database...
