What is a Database System?

A database system is a software system that enables the creation and management of databases. A database is a collection of interrelated data, and a database management system (DBMS) is the software that allows users to create, access, modify, and delete data in a database. DBMSs also provide features for security, concurrency control, and data recovery.

Why Use a Database System?

There are many benefits to using a database system. These benefits include:
Data integrity: DBMSs enforce data integrity rules, which help to ensure that data is accurate and consistent.
Data security: DBMSs provide features for data security, such as encryption and access control, which help to protect data from unauthorized access.
Concurrency control: DBMSs provide features for concurrency control, which help to ensure that multiple users can access the same data at the same time without corrupting the data.
Data recovery: DBMSs provide features for data recovery, which help to protect data from loss in the event of a hardware or software failure.
Scalability: DBMSs are scalable, which means that they can be used to manage databases of any size.

How to Use a Database System

To use a database system, you need to first create a database. You can then create tables in the database, and insert data into the tables. You can also query the database to retrieve data. SQL (Structured Query Language) is the standard language for querying databases.
