A database, the heart of an information system, is a collection of all relevant facts organized in a series of integrated files.
A database is a planned grouping of material that has been arranged and is often kept electronically in a computer system. A database management system often oversees a database (DBMS). The term "database system," which is frequently abbreviated to "database," refers to the combination of the data, the DBMS, and the applications that are connected to it.
To facilitate processing and data querying, the most popular types of databases currently in use typically model their data as rows and columns in a set of tables. The data may then be handled, updated, regulated, and structured with ease. For writing and querying data, most databases employ structured query language (SQL).
