Graphical tools for rule development in the active DBMS SAMOS
Proceedings 13th International Conference on Data Engineering, 1997Co-Authors: A. Vaduva, S. Gatziu, K.r. DittrichAbstract:Summary form only given. Active database management systems (active DBMS) support the definition, management and execution of event/condition/action rules specifying Reactive Application behavior. Although the advantages of active mechanisms are nowadays well known, there is still no wide use in practice. One main problem is that especially for large rule sets, defined by different persons at different points in time, potential conflicts and dependencies between rules are hard to predict and rule behavior is difficult to control. Therefore, tools are needed to assist the development and maintenance of rule bases. These tools should provide for graphical interfaces supporting both, "static" activities (performed during rule specification) such as rule editing, browsing, design, rule analysis, and "dynamic" activities (performed at runtime, during the execution of an Application) such as testing, debugging and understanding of rule behavior. The aim of the article is to show the use of three of these tools, namely the rule editor, the browser and the termination analyzer in the process of developing Applications for the active object oriented DBMS SAMOS.

Unified enhanced time Petri net models for development of the Reactive Applications
2017 3rd International Conference on Event-Based Control Communication and Signal Processing (EBCCSP), 2017Co-Authors: Tiberiu S. Letia, Attila O. KilyenAbstract:The Reactive Application development requires models that comprise continuous and logic variables, and reacts continuously and asynchronously to external and internal events. The newly proposed models called Unified Enhanced Time Petri Nets (UETPNs) endow the transitions of Time Petri Nets (enhanced with input and output channels) with mappings that include fuzzy logic features and arithmetic operations. The mappings are used to control the flow of the execution and to calculate the model states. The places have assigned real variables and so the contained tokens are real numbers. Extending the classical fuzzy logic sets with the empty set allows the construction of fuzzy logic rule sets that can model besides the fuzzy Petri nets capabilities the inhibitor arcs and reset arcs. The UETPN can model concurrency, selection, reaction to internal and external events and temporal behavior with fixed and variable delays. An algorithm to execute the UETPN models is provided with some examples of its use for Application developments.

KSE - Cloud data architecture applied to urban management
2016 Eighth International Conference on Knowledge and Systems Engineering (KSE), 2016Co-Authors: Florent Devin, Astrid Jourdan, Dominique LafflyAbstract:Open Data now provides access to updated data dedicated to urban development. The traditional approach of using production data for decision on land management needs to be rethought in the light of these new opportunities and should therefore addressed towards dynamic management of geographic information. Institutional sites such as INSEE semantically annotate their data facilitating the discovery of contextual data. Linked Open Data cloud network offers semantic access to a huge amount of thematic data including an important geographic subset. These new opportunities always generate a greater amount of usable data. Big Data tools, like Spark, make it easy to handle this amount unbounded data via conventional data-mining algorithms. We group all these issues under the generic name of Cloud Data that has sense only if it is integrated perfectly into a cloud computing environment for efficient processing and Reactive Application (SaaS Application, Restfull services, D3JS library, …). We offer an example of a dedicated Application for the Pau urban community in which all Cloud Data is integrated as a SaaS (Software as a Service).
