Zusammenfassung: | A computing workflow system has a workflow process definition contained in a workflow table as script functions. The workflow table is part of an extended database schema operating with an extended store, a workflow engine and a script engine. The novel workflow system includes a server database having a data table and an associated workflow table. A workflow extended store is communicatively coupled to the server database. A workflow engine is also communicatively coupled to the server database and to the workflow extended store. Further, a script engine is communicatively coupled to the workflow engine. The workflow table includes workflow rules and associated code to be executed by the workflow engine. Each row of the workflow table represents a workflow step. Script functions are defined in the workflow table to evaluate the condition and execute the action of each workflow step. The rules and associated code in the workflow table is both declarative and procedural. The workflow engine compares the data change information from the extended store procedure with the workflow definition in the workflow table and determines the appropriate step that needs to be executed. Then it checks execution permissions on that step. If execute permission is granted, the workflow engine evaluates the workflow step condition against the workflow table and, if true, it executes the step action. Upon completing the step action, the workflow engine commits all the changes made to the current item or to other items in the database.
L'invention concerne un système de circulation automatisée des documents, dont la définition du processus de circulation des documents est contenue dans une table, sous la forme de fonctions de script. Ladite table fait partie d'un schéma de base de données fonctionnant avec une mémoire étendue, un moteur de circulation de documents et un moteur de scripts. Un moteur de circulation de documents est également relié à la base de données serveur ainsi qu'à la mémoire étendue de la circulation de documents. En outre, un moteur de scripts est relié de manière communicative audit moteur de circulation des documents. La table de circulation des documents comporte des règles particulières ainsi qu'un code associé devant être exécuté par le moteur de circulation des documents. Chaque ligne de la table de circulation des données représente une étape de cette circulation. Des fonctions de script sont définies dans la table de circulation des documents, qui |
