A map of a database that shows tables and relationships is called Schema.
A database is a structured collection of related data that has been systematically organized and is kept in a way that makes it simple to manage and update. It serves as the central repository for all data, comparable to a library's collection of books spanning a variety of genres. Imagine data as a library.
The data can be set up in a database in the form of a table with rows and columns. The data can be easily located and retrieved whenever necessary by indexing it. With the aid of databases, a large number of websites on the Internet are operated. Database handlers are used to build databases that allow users to access the data using just one set of software applications.
