Introduction to Database Management Systems

Database Management Systems (DBMS) are software systems designed to store, manage, and facilitate access to databases, which are structured collections of data. They serve as the intermediary between the user and the database, ensuring data is consistently organized and easily accessible. A DBMS supports various functions such as data storage, retrieval, update, and administration, making it crucial for handling large volumes of data efficiently. For instance, a university may use a DBMS to manage student records, course registrations, and faculty information, allowing for streamlined operations and quick access to information.
