Introduction to Database and DBMS
- A database is a shared collection of logically related data and a description of this data, designed to meet the information needs of an organization.
- A database includes data and schema, where schema refers to data definition, system catalog, description, dictionary, or metadata and structure.
- System catalog (metadata) provides description of data to enable program–data independence.
Database Management System (DBMS)
- A DBMS is a software system that enables users to define, create, maintain, and control access to the database.
- A DBMS includes several components:
- Data definition language (DDL) - permits specification of data types, structures, and data constraints.
- Data manipulation language (DML) - a general enquiry facility (query language) of the data.
- Controlled access to the database, including:
- A security system
- An integrity system
- A concurrency control system
- A recovery control system
