A database is an organized set of information. This information is usually on one particular topic. An example of a database is a card file that contains names, addresses, phone numbers, and parents' names of the students in your class. A recipe file is another example of a database.
Every database is made up of records. Each record contains all the pertinent information about one student.
Each record is composed of fields. A field contains one piece of information about the student (their first name, or their last name, or their birthdate).
Maintaining a computer database allows for easy manipulation of the data. It also allows for easy modification and reorganization of the information it contains.
