Abstract

A software system development apparatus is provided. The software system development apparatus may include a processor and a computer-readable medium operatively coupled to the processor. The apparatus may also include a system design tool program stored on the computer-readable medium that, when executed by the processor, is operable to regulate user access to at least one aspect of the system design tool according to one or more authorization categories of users of the system design tool. The system design tool may also be operable to generate a real-time embedded control software system by selecting from a collection of reusable software components stored and described in a catalog in accordance with the Reusable Asset Specification (RAS).

Claims

1. A software system development apparatus hosted by a host organization, comprising:

a processor;

a computer-readable medium operatively coupled to the processor;

a system design tool program stored on the computer-readable medium that, when executed by the processor, is operable to;

grant access to user computers inside and outside the host organization, wherein the user computers are remote from the software system development apparatus;

store, in accordance with the Reusable Asset Specification (RAS), a collection of reusable software components in a catalog in the system design tool program;

generate, in response to commands from one of the user computers, a real-time embedded control software system by selecting one or more software components from the collection of reusable software components stored in the catalog, as well as from one or more collections of reusable software components stored in accordance with RAS outside the host organization, the real-time embedded control software system being generated on the processor of the host organization without any software components being downloaded to the user computers from the host organization; and

regulate user access to at least one aspect of the system design tool program according to one or more authorization categories of users of the system design tool program.

2. The apparatus of claim 1, wherein the reusable software components stored in the catalog are available for selection by systems external to the system design tool program.

3. The apparatus of claim 1, wherein the at least one aspect includes at least one of software components stored in the catalog and one or more features of the system design tool program.

4. The apparatus of claim 1, wherein the system design tool program is further operable to store the software system, generated using the system design tool program, in the catalog in such a manner as to be available for future use by users of the system design tool program.

5. The apparatus of claim 4, wherein the system design tool program is operable to store the software system, generated using the system design tool program, in the catalog only if the software system was designed with user access to the system design tool program under a predetermined authorization category.

6. The apparatus of claim 1, wherein the system design tool program is further operable to regulate user access to confidential software of the host organization that is stored in the catalog.

7. The apparatus of claim 1, wherein the system design tool program is further operable to regulate user access to one or more features of the system design tool program that are confidential to the host organization.

8. The apparatus of claim 1, wherein the one or more authorization categories are based, at least in part, on one or more different levels of performance of the system design tool program that are available to users of the system design tool program.

9. A software system development apparatus hosted by a host organization, comprising:

a processor;

a computer-readable medium operatively coupled to the processor;

a system design tool program stored on the computer-readable medium that, when executed by the processor, is operable to;

grant access to user computers inside and outside the host organization, wherein the user computers are remote from the software system development apparatus;

store, in accordance with the Reusable Asset Specification (RAS), a collection of reusable software components in a catalog in the system design tool program;

generate, in response to commands from one of the user computers, a real-time embedded control software system by selecting one or more software components

wherein the real-time embedded control software system is generated on the processor of the host organization without any software components being downloaded to the user computers from the host organization;

wherein the system design tool program is configured to be able to select software components from the collection of reusable software components stored in the catalog; and

wherein the reusable software components stored in the catalog are available for selection by systems outside the host organization; and

regulate user access to at least one aspect of the system design tool program according to one or more authorization categories of users of the system design tool program.

10. The apparatus of claim 9, wherein the at least one aspect includes at least one of software components stored in the catalog and one or more features of the system design tool program.

11. The apparatus of claim 9, wherein the system design tool program is further operable to store the software system, generated using the system design tool program, in the catalog in such a manner as to be available for future use by users of the system design tool program.

12. The apparatus of claim 11, wherein the system design tool program is operable to store the software system, generated using the system design tool program, in the catalog only if the software system was designed with user access to the system design tool program under a predetermined authorization category.

13. The apparatus of claim 9, wherein the system design tool program is further operable to regulate user access to confidential software of the host organization that is stored in the catalog.

14. The apparatus of claim 9, wherein the system design tool program is further operable to regulate user access to one or more features of the system design tool program that are confidential to the host organization.

15. The apparatus of claim 9, wherein the one or more authorization categories are based, at least in part, on one or more different levels of performance of the system design tool program that are available to users of the system design tool program.

16. A method of developing a software system, comprising;

granting access to a system design tool program, stored by a host organization, to user computers inside and outside the host organization, wherein the user computers are remote from a software system development apparatus on which the system design tool program is stored, the system design tool program including a catalog which stores a collection of reusable software components in accordance with Reusable Asset Specification (RAS);

accessing the system design tool program under one of two or more authorization categories of users of the system design tool program, the authorization categories regulating user access to;

a collection of reusable software components, and

one or more features of the system design tool program;

using the system design tool program to access and select one or more reusable software components from a collection of reusable software components stored in accordance with RAS inside the catalog and outside the host organization; and

generating, in response to commands from one of the user computers, an embedded control software system utilizing the one or more software components selected from the collection stored inside the catalog and outside the host organization without downloading any software components to the user computers from the host organization.

17. The method of claim 16, wherein the reusable software components stored in the catalog are available for selection by systems external to the system design tool program.

18. The method of claim 16, further including storing the embedded control software system in the catalog in such a manner as to be available for future use by users of the system design tool program.

19. The method of claim 16, wherein the method further includes accessing the system design tool program under an authorization category under which confidential software of the host organization that is stored in the catalog is available to the user of the system design tool program.

20. The method of claim 16, wherein the method further includes accessing the system design tool program under an authorization category under which features of the system design tool program that are confidential to the host organization are available to the user of the system design tool program.
