This means that the validity actions of the database management system over the data contained in it can be modeled and proved on a mathematical basis.Oracle, DB2, SQL Server, MySQL, etc. all implement most of the requirements of Codd's paper.It is worth noting that the relational model is the ONLYone where the affects of putting data in it can be proven.
