In database, one can perform operations such as storing, manipulating, and retrieving the data. It provides the relationship between the data items and data item groups. Self-describing: “Self-describing” is the property of database, which means that the database structure description is present within the database itself. It includes both data and met data. Extensible Markup Language (XML) is an example of self-describing text.
