Database
A database is a structured collection of data that is stored and managed digitally.
Databases are an essential tool for organizing and managing data in today's information society. They offer numerous benefits, including efficient data storage, improved decision-making, and increased productivity. Choosing the right database depends on the specific requirements and needs of the respective organization.
Properties of databases

- Efficient data management: Databases provide features to insert, delete, modify, and query data.
- Access and permission control: Permissions regulate who can access which data and which actions can be carried out.
- Data security: Mechanisms protect data from unauthorized access, alteration, and loss.
- Data integrity: Ensures that data is accurate, consistent, and up to date
- scalability: Databases can be adapted to growing data volumes and requirements.
