Zusammenfassung:	Abstract: "Relational database systems are very useful and widely accepted as the systems that handle large amounts of data efficiently. However, the expressive power of the data model is limited because of the restriction of the first normal form. This limitation prevents storage of knowledge representing data with a complicated structure to a traditional database system and prevents the realization of applications using large amounts of knowledge. The relational knowledge base (RKB) model was introduced to remove such limitations on the logic programming language. The RKB enables Prolog terms to be stored and manipulated within the framework of the relational model This paper introduces a manipulation language for sets of terms stored to the RKB. This manipulation language is embedded in the logical programming language and enables the logic programming language to manipulate large amounts of knowledge represented by terms. Because our manipulation language can manipulate terms using the unification operation, we can manipulate terms stored in the RKB without operational gaps from the unification based logic programming language.
