A relational database management system (rdbms) is computer software that enables users to create, modify, and analyze data in a relational database enterprise rdbms include: microsoft sql server oracle database. A program module that provides the interface between the low level data stored in the database and the application programs and queries submitted to the system. Every table in a relational database must have a primary key. so in this example, perhaps we could specify the combination of all the name and address fields as the primary key (or perhaps the combination of the 2 name fields along with the phone number). There are three main types of constraints in the relational model: key constraints entity integrity constraints referential integrity constraints another implicit constraint is the domain constraint every value in a tuple must be from the domain of its attribute (or it could be null, if allowed for that attribute) key constraints superkey of r:.
