A Database-Based Service for Handling Logical Variable
The paper discusses the use of a database as a service that
supports applications whose data flow is based on sets of tuples of
variable bindings, as e.g., in logic-based frameworks like Datalog
and similar rule-based approaches. The service also supports
cooperative work of different services on the bindings, thus
replacing the need for actual exchange of potentially large sets
of data during workflows.
The concrete usage scenario of the service is in a distributed
environment for processing ECA (Event-Condition-Action) rules and
processes over relational states.
