A database is a collection of data that is saved and organized to allow easy retrieval when needed. It is the collection of schema, tables, queries, reports, views, and other objects. Databases are not limited to only computers,Where databases are more complex they are often developed using formal design and modeling techniques.The database management system (DBMS) is the software that interacts with end users, applications, the database itself to capture and analyze the data and provides facilities to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a "database system". Often the term "database" is also used to loosely refer to any of the DBMS, the database system or an application associated with the database.
