....to filter the rule action) VenusDB [30] extends a C traditional rule based language to allow rule based applications to execute against standard relational databases. A third communityhas added rules to deductive databases, including object oriented deductive databases such as Coral [40]. Rules in deductive databases are run to satisfy queries and so have a very different purpose than rules in R . 26 Finally, our work (and much of the above related work) is similar to that of Lopez et al. 41] in that one of our motivations is a desire to declaratively express constraints ....

....languages (e.g. Parlog) to DBMSs [2] and to compiled, set at a time processing of logic queries against a database. Some of the significant efforts that also involve significant prototyping and in some cases performance evaluation include BERMUDA [6] BrAID [17] the LDL system [1] and Coral [14, 18, 15]. Our choice of the LDL system was guided by the merits of the system in functional terms, especially the ability of the LDL system to access commercial DBMSs of interest to us and its interface to C , as well as very important pragmatic considerations, such as: availability of technical ....

....available rule based expert system 2 languages have difficulties in handling composite objects as a unit of inference and limitations in supporting uncertainty and such a variety of data types. This has been pointed out as a major research issue by a number of research workers including [1, 2, 3]. Proposed in this paper is a composite object inference model that integrates an objectoriented paradigm and a traditional deductive mechanism. Although a deductive model has been predominantly used in many expert systems, the model alone cannot keep track of all the semantics of knowledge ....
....6. 2. Related Work 3 Considered in this paper is an integration of object oriented paradigm and fuzzy logic into a rule based language. This approach has gained a great amount of attention from many research workers, and thus a huge body of literature related with this issue is available [3, 11, 13, 14]. In this section, some of the important previous researches that are widely used for applications or have a particularly interesting variation of an issue under discussion are reviewed in three folds. First, rule based mechanisms adopting object oriented paradigm are described. Second, expert ....
