An Introduction and Treatment of User-Defined Data Types and Operators in Relational Database
To be applicable to various application fields,great attention has been paid to extendedtraditional DBMS's functions.In this paper,we propose the principle and method of an extendedrelational DBMS supporting user-defined data types and operators,discuss the effect of introducinguser-defined data types and operators upon DBMS,and present an implementation schema based ondata dictionary.
