Over time, three RDBMSes came to dominate in commercial implementations. A relational database is a database that allows administrators and users to set up connections among different data records, and to use those connections to view and manage data. This form of data storage is often called structured data. Not null -- this ensures that every column does not have a null value, such as an empty cell.
