Study Notes

Database Management System (DBMS)

  • The primary function of a DBMS is to manage and provide controlled access to a database, allowing users to store, retrieve, and modify data efficiently.
  • A DBMS facilitates various administrative operations, including:
  • Creating and modifying database structures, such as tables, indexes, and views
  • Enforcing data security and integrity constraints
  • Managing data storage and retrieval
  • Optimizing database performance
  • Providing backup and recovery services
  • Popular database software or DBMSs, such as MySQL and Oracle Database, play a crucial role in managing and storing large amounts of data efficiently.
  • A DBMS enables end users to interact with a database through various interfaces, such as:
  • Query languages, like SQL, to retrieve and manipulate data
  • Graphical user interfaces (GUIs) for interactive data manipulation and visualization
  • Application programming interfaces (APIs) for integrating databases with other software applications
