1. Test the existing environment When designing a new database, you should not only carefully study the business needs, but also examine the existing system. Most Databases Projects are not built from scratch. Normally, there will always be existing systems within the Organization to meet specific needs (there may be no real Automatically calculated ). Obviously, the existing system is not perfect, otherwise you do not have to create a new system. H
