ABSTRACT-Data mining is a process that uses a variety of data analysis tools to discover knowledge, patterns and relationships in data that may be used to make valid predictions. With the popularity of object-oriented database systems in database applications, it is important to study the data mining methods for object-oriented databases. The traditional Database Management Systems (DBMSs) have limitations when handling complex information and user defined data types which could be addressed by incorporating Objectoriented programming concepts into the existing databases. Classification is a well-established data mining task that has been extensively studied in the fields of statistics, decision theory and machine learning literature. This paper focuses on the design of an object-oriented database, through incorporation of object-oriented programming concepts into existing relational databases. In the design of the database, the object-oriented programming concepts namely inheritance and polymorphism are employed. The design of the object-oriented database is done in such a well equipped manner that the design itself aids in efficient data mining. Our main objective is to reduce the implementation overhead and the memory space required for storage when compared to the traditional databases.

Abstract: In this paper a run-time model is proposed. The run-time model enforces integrity constraints for attributes that are derived from composition and inheritance hierarchies. The run-time model is designed for enforcing the logical integrity constraints in object-oriented databases during the run-time. A new technique called detection method is designed to check the object meta data to detect and catch the object-oriented databases violation before it occurs. Furthermore, we have implemented the RTM and supported set of definitions that are for checking attribute values validity, object-oriented databases consistency, and also a method for verifying attribute values when inserting, deleting, and updating objects. Keywords: Object-oriented databases, integrity constraints, constraints violation.
