ABSTRACT
One of the fundamental services provided by a multi-user computer system has always been access to shared data. The shared data, once counted in megabytes, are now usually counted in gigabytes.

To protect the data and manage storage requires a combination of hardware protection, operating systems services, and software tools. There are two main problems — maintaining data integrity and storage management.
