This is a user-created direction that tells the database to find specific records. A database is an organized collection of information. Databases typically store all their data in one large table. A computerized database can store millions of telephone numbers. Object oriented database management system advantages disadvantages disadvantage of computerized databases is that they limit your ability to arrange information.

The same features that make databases efficient tools also enable them to keep data secure.
