Abstract

Claims (47)

1. A method for externalizing data comprising:

providing a domain specification which includes domain-specific business objects, domain-specific services, and domain-specific activity types, and links between them;

extracting a reusable data model from the domain specification, the data model including a set of business objects linked by data relations, at least some of the business objects in the data model being linked to a domain-specific activity type by a respective one of a set of defined business object relations;

with a database generator, generating a relational database from the data model, which stores a collection of reusable business objects and their business object relations;

automatically generating a platform-independent application program interface, the relational database being accessible through the application program interface, the application program interface updating and saving data to the relational database and fetching data from the relational database;

providing for a user to generate a domain-specific process model with links to business objects in the domain specification, including, with a graphical user interface generator, generating a graphical representation of the process model using graphical description templates for representing process steps in the graphical representation, for display to the user on a graphical user interface;

with a domain-independent generator, automatically transforming the domain-specific process model to a domain-independent process model which has access to the database through the application program interface;

wherein the extracting, generating, providing and transforming are performed with a processor.

2. The method of claim 1 , wherein in the domain specification, each business object is a governed object and has a set of features.

3. The method of claim 1 , wherein in the domain specification, at least some of the business objects are each linked to a different business object by a data relation.

4. The method of claim 1 , further comprising instantiating the domain specification from a domain meta-model.

5. The method of claim 1 , wherein the application program interface is a REST-API.

6. The method of claim 1 , wherein the domain-specific process model includes graphical representations of elements of the process.

7. The method of claim 1 , wherein the domain-independent process model is in BPMN.

8. The method of claim 1 , wherein the transforming includes applying a set of generation patterns which take into account the business object relations between the domain-specific activity types and the business objects in order to create activities, in a domain-independent language, that are able to access business objects through the application program interface.

9. The method of claim 8 , wherein each of the generation patterns corresponds to one of the defined business object relations between domain-specific activity types and the business objects.

10. The method of claim 1 , wherein the domain specification is an instance of a domain meta-model, the domain-specific process model is an instance of a process meta-model and the domain-independent process model is an instance of a domain-independent meta-model.

11. The method of claim 1 , wherein the transforming includes combining the domain specification and the domain-specific process model to generate the domain-independent process model in BPMN, the BPMN process model being an instance of a BPMN meta-model.

12. The method of claim 1 , further comprising executing a process including generating one or more calls to the application program interface to perform functions with respect to business objects in the database.

13. The method of claim 12 , wherein the functions are selected from the group consisting of:

creating a new business object in the database;

updating an existing business object in the database;

reading an existing business object in the database;

deleting an existing business object in the database; and

combinations thereof.

14. A system comprising memory which stores instructions for performing the method of claim 1 and a processor, in communication with the memory, for executing the instructions.

15. A computer program product comprising non-transitory memory storing instructions which, where executed by a computer, perform the method of claim 1 .

16. A system for externalizing data comprising:

a database and application program interface generator which:

generates a relational database from a data model of a domain specification, the data model including a set of business objects linked by data relations, at least some of the business objects in the data model being linked to a domain-specific activity type by a business object relation, the relational database storing a collection of reusable business objects and their business object relations, and

generates a platform-independent application program interface for accessing the data model, the application program interface updating and saving data to the relational database and fetching data from the relational database;

a process specification component which provides for a user to generate a domain-specific process model with links to business objects in the domain specification, including, with a graphical user interface generator, generating a graphical representation of the process model using graphical description templates for representing process steps in the graphical representation, for display to the user on a graphical user interface;

a domain-independent generator for transforming the domain-specific process model to a domain-independent process model which has access to the database through the application program interface; and

at least one processor for implementing the database and application program interface generator, process specification component, and generator for transforming the domain-specific process model to the domain-independent process model.

17. The system of claim 16 , further comprising a domain specification component for assisting a user in specializing a domain meta-model to generate the domain specification.

18. The system of claim 16 , wherein the database is resident on a separate computing device from at least one of the database and application program interface generator, process specification component, and generator for transforming the domain-specific process model to the domain-independent process model.

19. A method for externalizing data comprising:

instantiating a domain specification as an instance of a domain meta-model, the domain specification including a set of business objects;

instantiating a domain-specific process model as an instance of a process meta-model;

extracting a reusable data model from the domain specification, the data model including the set of business objects linked by data relations, at least some of the business objects in the data model being linked to a domain-specific activity type by a respective one of a set of defined business object relations;

generating a platform-independent application program interface;

generating a relational database from the data model which is accessible through the application program interface, the relational database storing a collection of reusable business objects and business object relations;

generating a domain-independent process model from the domain-specific process model and the domain specification, the domain-independent process model being an instance of a domain-independent process meta-model, the domain-independent process model having access to the database through the application program interface, the generating including, with a graphical user interface generator, generating a graphical representation of the process model using graphical description templates for representing process steps in the graphical representation, for display to the user on a graphical user interface; and

executing a process with the domain-independent process model, including generating one or more calls to the application program interface to perform functions with respect to business objects in the database.

20. The method of claim 19 , wherein the meta-model provides for:

linking a business object in the domain specification to a different business object in the domain specification with a data relation; and

linking a business object in the domain specification to a domain-specific activity type with a business object relation.
