Abstract

A hardware/software system for developing a software application by component modeling and instantiation is disclosed. The system has at minimum a computerized workstation with a GUI for enabling user control of system entities, a data repository for storing data particulars necessary for application development, a server application for providing data particulars and functionality required for component development, a processor for hosting the server application, and a modeling program accessible to the workstation and to the server application for design, construction, and testing application components. In a preferred embodiment, the application components are separately defined, built and tested using the modeling program and server functions wherein the coding required to generate and enable each application component from model information is automatically generated by the modeling program.

Claims

1. A hardware/software system for developing a software application by component modeling and instantiation comprising:

at least one computerized workstation having a graphic user interface associated therewith connected to the system for enabling user interaction with and manipulation of system entities;

at least one data repository connected to the system for storing data particulars necessary for application development;

at least one server application connected to the system for providing data particulars and functionality required for component development;

at least one computerized processing machine connected to the system for hosting the at least one server application; and

a modeling program accessible to the at least one computerized workstation and to the server applications for design, construction, and testing application components;

characterized in that the application components are separately defined, built and tested using the modeling program and server functions wherein the coding required to generate and enable each application component from model information is automatically generated by the modeling program as a result of ordered invocation of model instances of the application components.

2. The system of claim 1 wherein there are a number of computerized workstations each having a graphic user interface manned by a like number of users comprising a development team.

3. The system of claim 1 wherein the data particulars necessary for application development include at least one persistent library of code.

4. The system of claim 1 wherein there are a number of server applications dedicated to separate functionalities.

5. The system of claim 4 wherein the functionalities include repository server, source server, build server, and test server.

6. The system of claim 1 wherein the modeling program includes code generators and language processors that are invoked and operate in an automated fashion.

7. The system of claim 1 wherein the data particulars for component development include modeling and coding workspaces.

8. The system of claim 1 wherein each component has it'"'"'s own workspace reserved for design and construction.

9. A process for developing a software application through component-based modeling comprising steps of:

(a) identifying the required application components of the application to be developed in terms of requirements for use and in terms of functionality expected;

(b) designing and modeling the required components according to user expectations;

(c) specifying the application logic for each modeled component;

(d) generating code defining a component from each modeled component instance;

(e) testing each component generated; and

(f) deploying the successfully tested components as a finished application.

10. The method of claim 9 wherein in step (b), use-case diagrams are created for each component.

11. The method of claim 9 wherein step (b) also includes creating a sequence diagram for every use-case diagram.

12. The method of claim 9 wherein in step (d) the code generation is automated through use of at least one code generator.

13. The method of claim 9 wherein in step (e) testing is performed automatically in a server.

14. The method of claim 9 wherein in step (f) deployment is scheduled.
