Databases store loads of auxiliary data such as indexes, aggregate tables, materialized views and other structures where the original data is repeated. Many times databases repeat the data in these structures for the sake of achieving better performance gains for the applications and reports they serve. Similarly, a database management system (DBMS) is a software for creating and managing data in the databases. The DBMS provides users and programmers a defined process for data retrieval, management, updating, and creation.
Topics include data models (relational, document, key/value), storage models (n-ary, decomposition), query languages (SQL, stored procedures), storage architectures (heaps, log-structured), indexing (order preserving trees, hash tables), transaction processing (ACID,
