A database is an organized collection of data, today typically in digital form. The data are typically organized to modelrelevant aspects of reality (for example, the availability of rooms in hotels), in a way that supports processes requiring this information (for example, finding a hotel with vacancies).
Theterm database is correctly applied to the data and their supporting data structures, and not to the database management system (DBMS). The database data collection with DBMS is called database system.
Theterm database system implies that the data is managed to some level of quality (measured in terms of accuracy, availability, usability, and resilience) and this in turn often implies the use of ageneral-purpose database management system (DBMS).[1] A general-purpose DBMS is typically a complex software system that meets many usage requirements, and the databases that it maintains are often largeand complex. The utilization of databases is now so widespread that virtually every technology and product relies on databases and DBMSs for its development and commercialization, or even may have suchsoftware embedded in it. Also, organizations and companies, from small to large, depend heavily on databases for their operations.
Well known DBMSs include Oracle, IBM DB2, Microsoft SQLServer, Microsoft Access, PostgreSQL, MySQL, and SQLite. A database is not generally portable across different DBMS, but different DBMSs can inter-operate to some degree byusing standards like SQL and ODBC together to support a single application. A DBMS also needs to provide effective run-time execution to properly support (e.g., in terms of performance, availability, and security) as many end-users as needed.
Away to classify databases involves the type of their contents, for example: bibliographic, document-text, statistical, or multimedia objects. Another way is by their application area, for...
