Transitional Monitoring of Dynamic Inegrity Constraints

Database specification should include not only the static structure of a database system, but also its dynamic behaviour. In order to determine admissible sequences of states dynamic integrity constraints may be utilized. They give conditions on state transitions as well as long-term relations between database states in a descriptive manner. Complementarily, predefined transactions, i.e. basic ...

Active Data Mining

We introduce an active data mining paradigm that combines the recent work in data mining with the rich literature on active database systems. In this paradigm, data is continuously mined at a desired frequency. As rules are discovered, they are added to a rulebase, and if they already exist, the history of the statistical parameters associated with the rules is updated. When the history starts ...

Publishing and Querying the Histories of Archived Relational Databases in XML

There is much current interest in publishing and viewing databases as XML documents. The general benefits of this approach follow from the popularity of XML and the tool set available for visualizing and processing information encoded in this universal standard. In this paper, we explore the additional and unique benefits achieved by this approach on temporal database applications. We show that...

Using Smodels (Declarative Logic Programming) to Verify Correctness of Certain Active Rules

In this paper we show that the language of declarative logic programming (DLP) with answer sets and its extensions can be used to specify database evolution due to updates and active rules, and to verify correctness of active rules with respect to a specification described using temporal logic and aggregate operators. We classify the specification of active rules into four kind of constraints w...

Ode as an Active Database: Constraints and Triggers

The Ode object-oriented database provides facilities for associating constraints and triggers with objects.Constraints and triggers are associated with class (object type) definitions which makes them easy to read,to implement, and to blend with object inheritance. In this paper, we state our design goals in providingtrigger and constraint facilities for an object-oriented database,...
