Deductive and Active Databases
In this chapter we overview deductive and active databases which are the two different paths that have been followed towards the integration of rules in database systems. We do not extensively present every theoretical and/or implementation detail of these systems, but we mainly focus on the issues that will prove useful for the understanding of the unification of various rule systems that will be discussed in the next chapter.
