Thread: Relational database

Hi. I am MCA student. I am learning SQL database language. I want to know what relational database is. Also give me a suitable example. I am not getting any information for my subject. Thanks in advanced.

A relational database contains well defined relations consisting of attributes and their values. These relations are called tables and the attributes are the columns and their values. A database may contain different tables having relationships among them. This relationship facilitates no difficulty in querying and responses against the backend database tables.

A relational database is a collection of data items organized as a set of formally-described tables from which data can be accessed or reassembled in many different ways without having to reorganize the database tables.The relation, which is a two-dimensional table, is the primary unit of storage in a relational database.A relational database is a set of tables containing data fitted into predefined categories.
