Abstract

A computer system is used to create an application. Application source code or an executable application is converted into an in-memory representation. The in-memory representation is stored in a database. Attributes of the database representation are selected for modification, and constraints are assigned to the modifications. Modifications and constraints are stored in the database to create an application template. A copy of the application template is made in the database, and modifications are performed on the copy in the database. The modified copy of the application template is retrieved from the database and used to create an executable application.

Claims

1. In a computer system providing an application authoring environment utilizing an object database, a method of creating a modified version of an application characterized by:

creating an application template from said application in said object database;

making a copy of said application template in said database;

modifying said copy of said application template in said database; and

generating an executable application from said modified copy.

2. The method of claim 1, wherein the creation of said application template is characterized by:

creating in memory an object representation of said application;

storing said object representation in said object database; and

converting said object representation into an application template.

3. The method of claim 2, wherein the conversion of said object representation into an application template is characterized by:

selecting at least one attribute of said object representation that is suitable for modification;

creating at least one metadata item that specifies the at least one attribute suitable for modification and specifies at least one requirement for the modification of said attribute;

aggregating each of said at least one metadata item;

associating said aggregated metadata with said object representation; and

storing said metadata with said object representation in said object database.

4. The method of claim 3, wherein the modification of said copy of said application template is characterized by:

selecting at least one metadata item associated with said copy of said object representation; and

modifying at least one attribute of said object representation specified in said metadata item in accordance with each of the at least one requirement for the modification of said attribute.

5. The method of claim 2, wherein generating an executable application is characterized by:

extracting said modified copy of said object representation to create a modified object representation in memory; and

generating an executable application from said modified object representation.

6. The method of claim 5, wherein the generation of an executable application is performed by generating a set of at least one human-readable source code file from said modified object representation and compiling said set of source code to produce an executable application.

7. The method of claim 5, wherein the generation of an executable application is performed directly from said modified object representation.

8. The method of claim 2, wherein the object representation in memory is created by parsing the source code of said application.

9. The method of claim 2, wherein the object representation in memory is created by decompiling the executable version of said application

10. The method of claim 1, wherein database operations are performed using a web services interface.

11. A computer system for creating a modified version of an application comprising:

an object database;

a template creation component configured to create an application template from said application in said object database;

a template editing component configured to modify a copy of said application template in said object database; and

an application generation component configured to generate an executable application from said modified copy of said application template.

12. The system of claim 11, wherein said template creation component is further configured to:

create in memory an object representation of said application;

store said object representation in said object database; and

convert said object representation into an application template.

13. The system of claim 12, wherein said template creation component is further configured to convert said object representation into an application template by:

selecting at least one attribute of said object representation that is suitable for modification;

creating at least one metadata item that specifies the at least one attribute suitable for modification and specifies at least one requirement for the modification of said attribute;

aggregating each of said at least one metadata item;

associating said aggregated metadata with said object representation; and

storing said metadata with said object representation in said object database.

14. The system of claim 13, wherein said template editing component is configured to modify said copy of said application template by:

selecting at least one metadata item associated with said copy of said object representation; and

modifying at least one attribute of said object representation specified in said metadata item in accordance with each of the at least one requirement for the modification of said attribute.

15. The system of claim 12, wherein said application generation component is further configured to:

extract said modified copy of said object representation from said object database to create a modified object representation in memory, and

generate an executable application from said modified object representation.

16. The system of claim 15, wherein said application generation component is further configured to generate an executable application from said modified object representation by:

generating a set of at least one human-readable source code file; and

compiling said set of source code to produce an executable application.

17. The system of claim 15, wherein said application generation component is further configured to generate an executable application directly from said modified object representation.

18. The system of claim 12, wherein said template creation component is further configured to create the object representation in memory by parsing the source code of said application.

19. The system of claim 12, wherein said template creation component is further configured to create the object representation in memory by decompiling the executable version of said application

20. The system of claim 11, wherein said object database is configured to utilize a web services interface.
