Maintaining Views Incrementally Extended Abstract
We present incremental evaluation algorithms to compute changes to materialized views in relational and deductive database systems, in response to changes (insertions, deletions, and updates) to the relations. The view deenitions can be in SQL or Datalog, and may use UNION, negation, aggregation (e.g. SUM, MIN), linear recursion, and general recursion. We rst present a counting algorithm that t...
متن کاملTemporal Views as Abstract Relations
Many natural languages use prepositions to mark relations between entities of various kinds – between physical entities and their spatial locations, between temporal entities and their temporal locations, between abstract entities of various kinds (e.g. between ideas and their ‘mental locations’). In the current paper I will show that the consequences of using prepositions to relate temporal en...

متن کاملDatabase Views on KR Classification (Abstract)
The database models for Object Database Systems (ODBMSs) include many modeling concepts that originate in semantic data models , that were formerly used for database design purposes, or in (object-oriented) programming languages. To some extent, research on data models and query languages for such ODB models has already reached a consensus , not on one particular model or language, but on the c...
متن کاملArchitectural Views for Computation , Coordination and Distribution - An Extended Abstract ?
CommUnity and its categorical foundations provide a formal approach to Software Architecture (SA). Several concepts such as (re)configuration and (higher-order) connector have been given precise definitions in this setting. One of the cornerstones of the approach is the separation between computation, coordination and distribution. In this paper, we take this separation one step further and def...
