Database management is the practice of organizing, storing, and retrieving data in an efficient and secure manner. It involves designing and maintaining a database structure that allows for easy data manipulation and retrieval.

Database systems can be broadly categorized into relational and non-relational databases. Relational databases are designed to store data in tables with predefined columns and rows, while non-relational databases are more flexible and can store data in various formats, such as document-oriented or graph-based.

Database management professionals use Structured Query Language (SQL) and other tools to manage database systems and ensure data accuracy, security, and privacy. They also work to optimize database performance and troubleshoot issues that arise with the database system.

Effective database management is critical for organizations that rely on data to make informed decisions, such as businesses, scientific research institutions, and governments. By managing data effectively, organizations can improve efficiency, reduce errors, and gain insights that lead to better outcomes.
