A database is a collection of information that is organized in such a manner that it can easily be accessed, managed, and updated. In short, databases can be classified according to types of content: full-text, bibliographic, images and numeric. In computing, databases are sometimes classified according to their organizational approach.
The most prevalent one is the relational database. It is a tabular formed database in which one can easily access the data in various ways and recognize the same. A distributed database is one that can be isolated or replicated between different points in a single network. An object-oriented programming database matches with the data defined in the object of classes and its subclasses.
Traditional databases are organized by records, fields, and files. A field is just one small piece of information; a record is one set of fields, and a file is a collection of plenty of records. The collection of programs enables one to organize, enter, and select data in a database. To access this information from a database, one needs a database management system, better known as DBMS.
