The document discusses database management systems (DBMS). A DBMS is a collection of data and programs that access and manage the data. It defines how data is structured and stored, and provides mechanisms to manipulate the data. The DBMS ensures data safety and provides convenient and efficient data storage and retrieval. Common uses of DBMSs include sales, accounting, banking, finance, universities, airlines, and telecommunications. A DBMS controls data access, enforces data integrity, manages concurrency control, recovers databases after failures, and maintains database security.
