Knowledge Discovery in Object-Oriented and Active Databases
Jun Han · 1993
Knowledge discovery in databases (or data mining) , which extracts interesting knowledge from large databases, represents an important direction in the development of data- and knowledge- base systems. With fruitful research results on knowledge discovery in relational databases and the emerging trend in the development of object-oriented and active database systems, it is natural to investigate knowledge discovery in object-oriented and active databases. This paper overviews the mechanisms for knowledge discovery in object-oriented and active database systems, with an emphasis on the techniques for generalization of complex data objects, methods, class hierarchies and dynamically evolving data, and on the integration of knowledge discovery mechanisms with production control processes. 1 Introduction With rapid growth in the amount of information stored in databases, the development of effective and efficient tools for knowledge discovery in databases (KDD, or data/knowledge mining) ...
