....Active Rule Execution (FL ARE) model that provides the basic concepts for describing the execution of rules. We also provide a formal description of this model. 1 A RDL [SKM92] Ariel [Han89] Beeri Milo [BM91] Chimera [CFPT95a] EXACT [DPG91] HiPAC [DBB 88] Informix, NAOS [CCS94, Col98] Ode [AG89] Oracle [Ora92] Postgres [SHH87] REACH [BBKZ92] SAMOS [Da86] Sentinel [CAM93] Starburst [WF90] TriGS [KRRV94] 2.2 The FL ARE Model FL ARE is not yet another rule execution model but might be considered as a proposal of standard for active rule execution models.

....(for each module using this strategy) transitively with respect to the global triggering tree. Thus we consider that D3 and D4 are both triggered by D1. Note that under the hypothesis we made, the execution model of N built using FL ARE is the one of the existing active rule system NAOS [CCS94, Col98] We show ( Cou96] in the same way that most functionalities of most existing active systems can be covered by FL ARE 4 . This shows the power and genericic nature of the model. 4 See footnote in page 3 for a complete list of these systems. 6 Formal Semantics of the Model The formal ....
