DBMS Advantages

Question:
Our business is just starting to look at using a relational database management system. We are currently using computers, but the users have their own copies of whatever data they need to work with. What are the real advantages of using database management systems?

Answer:
There are several advantages. Here are some of them:

  • Centralized control — since all the data can be stored on one or more computers using the same database management software, it is easier to administer.
  • Since the data is centralized, there is no need to duplicate information. Unlike paper systems, every user can see a "copy" of the data without making actual new copies. Similarly, the database management system eliminates the need for duplication that results from using single-user, isolated application programs.
  • Again, because of centralization, the database management system can maintain a degree of accuracy that it not possible when data is stored throughout the organization. It also is easier to enforce standards.
  • Security of the organization's data is greatly improved when it is stored in a database management system — data can be restricted so that only those users who are authorized may see or manipulate it.
