Database management refers to the process of organizing, storing, and retrieving data in a database. It involves a set of activities that ensure that the data in the database is accurate, consistent, and up-to-date. Database management includes tasks such as data modeling, data storage, data retrieval, data security, data backup and recovery, and database performance tuning.

Data modeling involves designing the structure of the database, including the tables, fields, and relationships between them. Data storage involves choosing the right type of database and configuring it to store the data efficiently. Data retrieval involves querying the database to retrieve the required information.

Data security involves ensuring that the data in the database is protected from unauthorized access and that sensitive information is not compromised. Data backup and recovery involve creating regular backups of the database and having a plan in place to restore the database in case of data loss or corruption.
