Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for providing selective command control within a workflow management system or a computer system (WFMS) provided with a similar function. SOLUTION: Upon receiving an issued command directed to a process instance of a process model, this method and a corresponding system determines whether the current activity having control authority at that point of time is included in a command sphere in control flow of the process instance in a first step. The command sphere is provided with a sub-graph of an arbitrary graph and defines one or a plurality of permissible commands which are allowed or not allowed to be executed when control is within the command sphere. In a second step, the method and the corresponding system executes the issued command only if the issued command is defined as permissible.

Abstract: PROBLEM TO BE SOLVED: To assure the total atomicity of many transactions which are latently scattered and also to optimize the traffic necessary for cooperation of those transactions and the total parallel behavior and throughput of the transactions. SOLUTION: The fundamental concept of this method is based on a method that divides all transactions into groups, and every group is called 'transaction hierarchy' or just 'hierarchy'. Each of both hierarchies S1 and S2 is processed by an atomic protocol and these hierarchies are synchronized with each other. Thus, the ACID processing result is assured for every hierarchy. Therefore, a global transaction consisting of all groups of transactions to be obtained, i.e., all hierarchies is processed as a set of chained hierarchies based on the chained transaction processing principle. The execution of the chained hierarchies assures the atomic execution of the global transaction.

Abstract: The workflow process model defines a process activity which is selected and carried out by computer. One or more input containers and/or one or more output containers are associated with the process activity. The process model is connected with an environment for reusable parts in which the input and output containers are implemented as reusable parts. In an input container allocation step, an input container re-use part is associated with the model, which implements the input container and resides in the environment for reusable parts. The allocation is stored as an input container allocation specification in the process model. In an output container allocation step, an output container re-use part is associated with the model, which implements the output container and resides in the environment for reusable parts. This step also involves storing the allocation as an output container allocation specification in the process model.

Abstract: The steps required to generate the code for the activity, include:- Analysis of the specification of the processing model, generation of the programme title or heading, generation of the copying of the method parameter defined with IN or IN-OUT from the input container fields as defined in the imaging rules, generation of subject-object-model (SOM) object production, generation of the method call-up, generation of the systems management and the use-exception situations, generation of the copying of the method parameters defined by OUT or IN-OUT in the output container field as defined in the imaging rules, and generation of the clearing of the variables of the method parameters.
