    Abstract: 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.

    Abstract translation: 计算工作流系统具有作为脚本功能的工作流表中包含的工作流流程定义。 工作流表是使用扩展存储，工作流引擎和脚本引擎运行的扩展数据库模式的一部分。 新颖的工作流系统包括具有数据表和相关工作流表的服务器数据库。 工作流扩展存储器通信地耦合到服务器数据库。 工作流引擎还可通信地耦合到服务器数据库和工作流扩展存储。 此外，脚本引擎通信地耦合到工作流引擎。 工作流程表包括要由工作流引擎执行的工作流程规则和相关代码。 工作流表的每一行表示一个工作流步骤。 脚本功能在工作流表中定义，以评估条件并执行每个工作流步骤的操作。 工作流表中的规则和关联代码都是声明式和程序性的。 工作流引擎将来自扩展存储过程的数据更改信息与工作流表中的工作流定义进行比较，并确定需要执行的适当步骤。 然后它检查该步骤的执行权限。 如果授予执行权限，则工作流引擎将根据工作流表来评估工作流步骤条件，如果为true，则执行步骤操作。 完成步骤操作后，工作流引擎将提交对当前项目或数据库中其他项目所做的所有更改。
