In the context of databases, data refers to all the single items that are stored in a database, either individually or as a set. Data is the raw material that can be processed for any computing machine. A database is an organized collection of structured information, or data, typically stored electronically in a computer system. A database management system (DBMS) is system software for creating and managing databases. A DBMS makes it possible for end-users to create, protect, read, update, and delete data in a database. The DBMS provides a centralized view of data that can be accessed by multiple users from multiple locations in a controlled manner. A DBMS serves as an interface between an end-user and a database, allowing users to create, read, update, and delete data in the database.
