A TRANSITIVE CLOSURE EXTENSION TO EXISTING RDBMS: APPROACH AND ALGORITHMS
Transitive closure is a very useful function for some applications.However,such an important function is not available in most RDBMS products.This paper presents the design and algorithm of an extension layer SETCS to existing RDBMS,which provides transitive closure evaluation function and an interface SQL* with corresponding extension to SQL.SETCS has been implemented in ORACLE.
