Database designing is the process of creating a data model for an information system. Designing a database that is fast, flexible, and efficient is not easy. It involves learning and analysing an organisation’s information needs. To build the dynamic, high-performance database that your organisation requires, you need to use data modelling that includes the art of creating visual representations of a database’s data, relationships, and other elements.
The proper tool simplifies and speeds the complex tasks, here are some of the best free tools for managing, comparing, administering and developing databases.
