Database, also called electronic database, any collection of data, or information, that is specially organized for rapid search and retrieval by a computer. Read the Britannica article to know more.

Formally, a "database" refers to a set of related data and the way it is organized. Access to these data is usually provided by a "database management system" (DBMS) consisting of an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data). The DBMS provides various functions that allow entry, storage, and retrieval of large quantities of information and provides ways to manage how that information is organized. Here I have given some links to free e-database sites for reading as well as downloading its various contents.

Please noteSome database(s) may not allow downloading data and are subject to copyright and use of these for your library purposes violates the law of IPR.
