2.) What is a DBMS? Briefly describe the components of a DBMS. A DBMS is commonly known as a Database Management System. It can be defined as a collection of tools, features, and interfaces that enable users to add, update, manage, access, and analyze data (Tilley and Rosenblatt, 2017). Components: - Interfaces for Users, Database Administrators, and Related Systems: Users typically work with predefined queries and switchboard commands but also use query languages to access stored data (Tilley and Rosenblatt, 2017). Database Administrators are responsible for DBMS management and support. DBAs are concerned with data security and integrity, preventing unauthorized access, providing backup and recovery, audity trails, maintaining the database, and supporting user needs (Tilley and Rosenblatt, 2017). Related Information Systems are defined as a DBMS that can support sdeveral related information syustems that provide input to, and require specific data from, the DMBS. Unlike a user interface, no human intervention is required for two-way communications between the DBMS and teh related systems (Tilley and Rosenblatt, 2017). - Data Manipulation Language: A DML controls database operations, including storing, retrieving, updating, and deleting data. Most commercial DBMSs, like Oracle and DB2, use a DML (Tilley and Rosenblatt, 2017). - Schema: A schema is the complete definition of a database, including descriptions of all fields, tables, and relationships. Subschemas can also be used and defined as a view of the database used by one or more systems or users. They also define only those portions of the database that a particular system or user needs os is allowed access to (Tilley and Rosenblatt, 2017).
