Abstract

A computer design model processing system and methods are described that can create visual models of computer systems, store versions of design models in a centralized repository, automatically generate and deploy computer software systems in response to the stored computer design models, define dependencies between computer design models, and automate and assist the development of multiple, possibly dependent, computer design models by multiple developers.

Claims

1. A method for facilitating the modification of computer design models that each define a software program, the method comprising the steps of:

receiving a modified computer design model that is a modification of an original design model;

comparing the modified design model with the original to identify changed elements;

identifying design models other than the modified design model that are dependent on the changed elements of the modified design model; and

facilitating the modification of the identified other design models to accommodate the changed elements.

2. The method of claim 1 further comprising, prior to the receiving step, the step of facilitating the modification of a computer design model by displaying a graphical representation of the design model.

3. The method of claim 1 further comprising, prior to the receiving step, the step of creating referencing elements to other computer design models from the said computer design model.

4. The method of claim 1 further comprising, prior to the receiving step, the step of storing information about the design model in an XML file.

5. The method of claim 1 further comprising the step of automatically generating an executable program for use in an application server system in response to the modified design model.

6. The method of claim 1 further comprising the step of automatically generating a persistent data structure description for use in a relational database system in response to the modified design model;

7. The method of claim 1 wherein the said computer design model comprises:

a data persistency sub-model containing entity elements that define one or more data structures for storing data operated on by the said software program;

a data structure sub-model containing structure elements defining one or more hierarchical data structures for transmitting information from and to the said software program; and

a behavior sub-model containing action elements that define a set of sequential and conditional instructions that define a business rule of the said software program.

8. The method of claim 1 further comprising, prior to the comparing step, the step of storing the modified computer design model in a source control repository, the step comprising:

creating a new version record in the source control repository;

storing an XML file in the source control repository attached to the new version record;

extracting the design model interface specifications in XML format;

storing the design model interface specification in the source control repository attached to the new version record;

extracting a list of other design models to which the design model includes references to; and

storing the list of other design models to which the design model includes references to, attached to the new version record.

9. The method of claim 8, wherein the said source control repository is based on a relational database.

10. The method of claim 8, wherein the said step of extracting the design model interface specifications in XML format includes the sub-steps of:

generating an in memory representation of the model;

searching the in memory representation of the model to find elements defined as interface elements;

creating an XML element in the said design model interface specification for each entity interface;

creating an XML element in the said design model interface specification for each structure interface; and

creating an XML element in the said design model interface specification for each action interface;

11. The method of claim 8, wherein the said step of extracting a list of other design model models to which the design model includes references to, comprises:

creating an in memory representation of the model;

searching the in memory representation of the model to find referencing elements;

querying the source control system about the referenced other computer design model in response to the referencing elements.

12. The method of claim 1, wherein said step of comparing the modified design model includes the sub-steps of:

retrieving the original design model interface specification;

parsing the original design model interface specification to create a first in memory representation of the design model interface specification;

retrieving the modified design model interface specification;

parsing the modified design model interface specification to create a second in memory representation of the design model interface specification;

comparing the first and the second in memory representations to identify any elements that are deleted in the representation of the modified design model; and

comparing the first and the second in memory representations to identify any elements that are changed in the representation of the modified design model.

13. The method of claim 1, wherein said step of identifying design models other than the modified design model that are dependent on the changed elements comprises:

receiving a list of deleted or changed elements in the modified version of the design model;

retrieving a list of other design models that include references to the original design model from the source control system; and

determining which other design models include references to the deleted or changed elements in the modified version of the design model.

14. The method of claim 1, wherein the step of facilitating the modification of the identified other design models comprises:

receiving a list of other design models that depend on the deleted or changed elements in the modified version of the design model;

displaying the list of design models for review and selection; and

upon user command, providing each of the design models for modification of said referencing elements.

15. A system for facilitating the modification of computer design models that each define a software program, the method comprising the steps of:

a receiving module for receiving a modified computer design model that is a modification of an original design model;

a comparison module for comparing the modified design model with the original to identify changed elements;

an identification module for identifying design models other than the modified design model that are dependent on the changed elements of the modified design model; and

a facilitating module for facilitating the modification of the identified other design models to accommodate the changed elements.

16. A method for providing a first computer design model, comprising the steps of:

identifying references in the first computer design model to elements of other computer design models;

locating the most current interface specifications for the identified references to elements of other computer design models;

comparing the most current interface specification for the elements of other computer design models with previous interface specifications for the elements of other computer design models; and

determining, in response to the comparing step, whether any references in the first computer design model to elements of other computer design models are changed or missing.

17. The method of claim 16, wherein the said first computer design model is stored in a source control repository.

18. The method of claim 16, wherein the said first computer design model includes referencing elements to other computer design models.

19. The method of claim 16, further comprising, prior to the step of identifying references, the step of specifying a version of a computer design model to be provided, by displaying a graphical representation of the source control repository content.

20. The method of claim 16, wherein the step of identifying references comprises:

retrieving the first computer design model from the source control repository; and
