Software programs called database management systems (DBMS) are used to store, retrieve, and query data. Users can add, read, edit, and delete data from databases using a database management system (DBMS), which acts as an interface between an end-user and the database. DBMSs control the data, the database engine, and the database structure, enabling users and other applications to extract or modify the data. It also contributes to concurrency, uniform data management practices, and data security. The normalization technique, used in database schema design, allows DBMS to optimize the arrangement of data by dividing large tables into smaller ones when any of their properties have redundant values.
