THE DATABASE ENVIRONMENT:
A database defines a structure for storing information and it collects information that is organized in such a way that a computer program can quickly select desired pieces of data.

Some other problems that may exist is if artwork is removed and it is not enter into the database location it will not be updated. The reports also take too long to generate and scan the inventory. This requires the help of a user who has better access to the system rights. The administrator will have the rights to go in, access information and change and fix issues that occur. The basic employees will have limited rights to access certain information such as certain artist and artwork in the museum as well as dates that the artist will be in the museum.
