Introduction to Database Management System by Theo Ryan Book PDF Summary
Database Management Systems (DBMS) are software systems used to store, retrieve, and run queries on data. A DBMS acts as an interface between an end user and the database, allowing users to create, read, update, and delete data in the database. A DBMS manages data, the database engine, and the database schema, allowing users and other programs to manipulate or extract data. It helps provide data security, data integrity, consistency and consistent data management practices. A DBMS improves the organization of data by adopting a database schema design technique called normalization, which divides a large table into smaller tables. DBMS offers many advantages over traditional file systems, including flexibility and a more complex backup system. Database management systems can be classified based on various criteria such as data model, database distribution, or user numbers. The most widely used types of DBMS software are relational, distributed, hierarchical, object-oriented, and network.
