Abstract

A system includes a communication unit to receive a request to change a configuration of an application program, and a storage unit to access a configuration state that represents the configuration. The system further includes a processing unit to identify a further configuration state that is consistent with a system of rules. The further configuration state represents a further configuration that complies with the request. The processing unit uses an integrity preserving transition to change the configuration to the further configuration. The integrity preserving transition terminates with the further configuration when the integrity preserving transition changes the configuration.

Claims

1. A system comprising:

a communication unit to receive a request to change a configuration of an application program;

a storage unit to access a configuration state that represents the configuration of the application program; and

a processing unit;

to identify a further configuration state that;

is consistent with a system of rules; and

represents a further configuration that complies with the request;

and

to use an integrity preserving transition to change the configuration to the further configuration,

the integrity preserving transition terminating with the further configuration when the integrity preserving transition changes the configuration.

2. The system of claim 1, wherein the configuration state and the further configuration state represent processes of the application program and have elements that represent operations of the processes.

3. The system of claim 2, wherein the system of rules comprises semantic rules for relating elements of configuration states.

4. The system of claim 2, wherein the system of rules comprises syntactic rules for relating elements of configuration states.

5. The system of claim 4, wherein the system of rules comprises any one of the following formal languages for describing a workflow:

event-driven process chains, Petri nets, and yet another workflow language.

6. The system of claim 1, wherein the integrity preserving transition rolls back one or more partial changes of the configuration when a further partial change of the configuration fails.

7. The system of claim 1, wherein the integrity preserving transition changes the configuration in atomic units that comprise one or more partial changes, each partial change of an atomic unit being related by the system of rules to a further partial change of the atomic unit when the atomic unit comprises more than one partial change.

8. The system of claim 1, wherein the integrity preserving transition comprises partial changes that are independent of further partial changes of a further integrity preserving transformation for changing the configuration.

9. The system of claim 1, wherein a following integrity preserving transition changes the further configuration to a further following configuration following a termination of the integrity preserving transition.

10. A method comprising:

receiving a request to change a configuration of an application program;

accessing a configuration state that represents the configuration of the application program;

identifying a further configuration state that is consistent with a system of rules and that represents a further configuration that complies with the request; and

using an integrity preserving transition to change the configuration to the further configuration, the integrity preserving transition terminating with the further configuration when the integrity preserving transition changes the configuration.

11. The method of claim 10, wherein the configuration state and the further configuration state represent processes of the application program and have elements that represent operations of the processes.

12. The method of claim 11, wherein the system of rules comprises semantic rules for relating elements of configuration states.

13. The method of claim 11, wherein the system of rules comprises syntactic rules for relating elements of configuration states.

14. The method of claim 13, wherein the system of rules comprises any one of the following formal languages for describing a workflow:

event-driven process chains, Petri nets, yet another workflow language.

15. The method of claim 11, wherein identifying the further configuration state comprises checking in a first stage that elements of the further configuration state are consistent with semantic rules of the system of rules by at least one of adding content to and eliminating content from the process represented by the configuration state to obtain an intermediate configuration state and checking in a second stage that the elements of the further configuration state are consistent with syntactic rules of the system of rules by at least one of adding elements to and eliminating elements from the intermediate configuration state to obtain the further configuration state.

16. The method of claim 10 wherein the integrity preserving transition rolls back one or more partial changes of the configuration when a further partial change of the configuration fails.

17. The method of claim 10 wherein the integrity preserving transition changes the configuration in atomic units that comprise one or more partial changes, wherein each partial change of an atomic unit is related by the system of rules to a further partial change of the atomic unit when the atomic unit comprises more than one partial change.

18. The method of claim 10 wherein the integrity preserving transition comprises partial changes that are independent of further partial changes of a further integrity preserving transformation for changing the configuration.

19. The method of claim 10 wherein a following integrity preserving transition changes the further configuration to a further following configuration following a termination of the integrity preserving transition.

20. A computer program product that comprises:

a module to receive a request to change a configuration of an application program;

a module to access a configuration state that represents the configuration of the application program;

a module to identify a further configuration state that is consistent with a system of rules and that represents a further configuration that complies with the request; and

a module to use an integrity preserving transition to change the configuration to the further configuration, the integrity preserving transition terminating with the further configuration when the integrity preserving transition changes the configuration.
