Database managers

A database manager is a software system that enables users to store, organize, retrieve, and manipulate data. It's responsible for managing the data in a database by creating, modifying, and deleting database objects such as tables, views, and procedures.

The database manager also enforces data integrity rules, manages transactions, and provides security mechanisms to ensure that only authorized users can access or modify the data. It typically includes tools for managing the structure of the database, controlling user access and permissions, and querying the data.

Database managers are essential for businesses and organizations that deal with large amounts of data. They allow users to efficiently store and retrieve data, which can lead to improved decision-making and increased productivity. Popular examples of database management systems include MySQL, Oracle, SQL Server, and PostgreSQL.
