What does a database mean?

Answer 1

Database as the name suggest is the collection of records or data that are related to each other. There are mainly three type of database network database, object oriented database and hierarchical database. Database helps in maintaining data consistency and data integrity.

Answer 2

A database is a store of information, kept in a systematic way.

A good example is a telephone directory. Directories vary around the world, but each entry (a subscriber) typically has the following information: subscriber's name, address, phone number.

In a database, one entry (such the entry for one subscriber in the phone book) is a record.

Each of the categories (types) of information is called a field. In the phone directory SubscriberName is a possible name for one field, PhoneNumber is another. Fields are like the questions asked in printed or computer questionnaires: Name? email address? Date of birth? Each of these in a database would be a field.

A database may therefore be displayed as intersecting rows and columns, like a spreadsheet (in fact, Microsoft Excel is popular for keeping simple databases, and the software has a menu titled Data for carrying out database-type operations). By convention, each record occupies one row, and each field one column. Computer databases enable rapid retrieval of information. A typical question that an employee of a business could put to a database might be: Which customers have had outstanding accounts for at least 30 days, totaling at least $100? A computer system makes it easy to ask such queries, and quick to obtain accurate answers.

A computer application designed for creating and maintaining databases is called a database manager.
