HSC Information and Communication Technology Note 6th Chapter Database Management System. A database is an organized collection of data. A relational database, more restrictively, is a collection of schemas, tables, queries, reports, views, and other elements. Database designers typically organize the data to model aspects of reality in a way that supports processes requiring information, such as (for example) modeling the availability of rooms in hotels in a way that supports finding a hotel with vacancies. A database management system (DBMS) is a computer software application that interacts with end-users, other applications, and the database itself to capture and analyze data. A general-purpose DBMS allows the definition, creation, querying, update, and administration of databases.

A database management system (DBMS) is system software for creating and managing databases. The DBMS provides users and programmers with a systematic way to create, retrieve, update and manage data. Trends come and go, but your DB strategy shouldn’t be a flavor of the month. Learn why you shouldn’t get distracted by new DB technology, how Facebook is using an RDBMS to do the data slicing and dicing they can’t in Hadoop, and more.
A database is not generally portable across different DBMSs, but different DBMSs can interoperate by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one DBMS. Computer scientists may classify database-management systems according to the database models that they support; the most popular database systems since the 1980s have all supported the relational model – generally associated with the SQL language.[disputed – discuss] Sometimes a DBMS is loosely referred to as a “database”.
