Active database rules with transaction-conscious stable-model semantics
[chapter]
1995
Lecture Notes in Computer Science
Preserved Fulltext
In this paper, we introduce a durable change semantics for active database rules; this semantics improves Starburst's deferred activation notion with concepts taken from Postgres and Heraclitus and the ...
But in addition to these differences, active rules are also unique inasmuch as their meaning is intertwined with the concept of database transactions. ...
Active Rules as Deductive Rules We will now define a logic-based semantics for active rules with priority assignment. ...

We p r e s e n t a hierarchically structured transaction-oriented concept for a rule-based active database system. ...
While (ii) serves as a conceptual model of active rule behavior and allows to reason about properties of the speci ed transactions, (i) { together with the appropriate execution model { yields an operational ...
The active database manifesto, for example, requires as an essential feature that \: : : rule execution must have a clear semantics, ie must de ne when, how, and on what database state conditions are evaluated ...

Here we address four key issues in distributed and heterogeneous environments: event detection and notification, event composition, an active functionality service, and ontology support. ...
We show the need for ontology support at all levels in heterogeneous environments and present a distributed active functionality service that addresses the difficult issues of event composition in widely ...
The unbundling of active databases consists of separating the active part from active DBMSs and breaking it up into components providing services like event detection, rule definition, rule management, ...
