12. In a 1985 article, Codd published rules or principles that a DBMS must use to be considered “fully relational” Continue Criteria for a RDBMS
13. The relational database model is made up of many tables, called RELATIONS , in which related data elements are stored. The data elements are in rows , called TUPLES and columns, called ATTRIBUTES . Terminology's Related to RDBMS
14. The main objective of the relational database model is to allow complex logical relationships between records to be expressed in a simple fashion. Main Objective
15. There is no standard definition of what capabilities or attributes define either an Extended Relational Database Management System or an Object-Relational Database Management System (ORDBMS). Here, both are referred to as "Extended Relational." EXTENDED RDBMS
16. ERDBMSs have characteristics of both an RDBMS and an ODBMS (thus, the loose application of the ORDBMS label). ERDBMS products provide a relational data model and query language that have been extended to include many of the features that are typical of ODBMSs. OVERVIEW OF EXTENDED RDBMS
17. Extending the query language allows for the integration of well-understood query optimization techniques. Typically, programming capabilities are embedded in the query language. This capability is not to be confused with stored procedures that are provided by a number of relational vendors. With the ERDBMSs, programmers are able to write functions in conventional languages as well as in SQL. These functions can then be embedded in standard SQL statements in exactly the same manner as a DBMS vendor function (e.g., the Sybase getdate() function). FEATURE OF EXTENDED RDBMS
