Abstract

A human oriented object programming system provides an interactive and dynamic modeling system to assist in the incremental building of computer programs which facilitates the development of complex computer programs such as operating systems and large applications with graphic user interfaces (GUIs). A program is modeled as a collection of units called components. A component represents a single compilable language element such as a class or a function. The three major functionality are the database, the compiler and the build mechanism. The database stores the components and properties. The compiler, along with compiling the source code of a property, is responsible for calculating the dependencies associated with a component. The build mechanism uses properties of components along with the compiler generated dependencies to correctly and efficiently sequence the compilation of components during a build process.

Claims

1. A method for creating a model of a computer program in a memory of a computer system, comprising the steps of:

(a) the computer system creating a plurality of components, each component representing an element of the computer program in the memory of the computer system;

(b) the computer system creating a plurality of properties associated with each of the components in the memory of the computer system;

(c) the computer system determining the dependencies between each of the components of the computer program; and

(d) the computer system storing each of the components, and their associated properties and dependencies, in a database in the memory of the computer system.

2. The method as recited in claim 1, including the step of displaying information associated with the computer program in at least one window.

3. The method as recited in claim 1, including the step of storing a plurality of attributes in the database associated with a particular component.

4. The method as recited in claim 1, including the step of storing the database on a disk.

5. The method as recited in claim 1, including the step of storing information associated with a particular component in a property associated with the component in the database.

6. The method as recited in claim 1, including the step of accessing the information in the database to perform compiles.

7. The method as recited in claim 1, including the step of accessing the information in the database to perform edit operations.

8. The method as recited in claim 1, including the step of accessing the information in the database to perform link operations.

9. The method as recited in claim 1, including the step of accessing the information in the database to perform load operations.

10. The method as recited in claim 1, including the step of the computer system storing a unique name and a container identification in a property associated with a particular component.

11. The method as recited in claim 1, including the step of the computer system storing a declaration property representing the compiled symbol table entry associated with a particular component.

12. The method as recited in claim 1, including the step of storing object code in a property associated with a particular component.

13. The method as recited in claim 1, including the step of storing a client in a property associated with a particular component.

14. The method as recited in claim 1, including the step of storing a reference in a property associated with a particular component.

15. The method as recited in claim 1, including the step of storing a kind associated with each component in the database.

31. The method as recited in claim 1, including the step of storing an interface property associated with a particular component.

32. The method as recited in claim 1, including the step of storing an implementation property associated with a particular component.

33. The method as recited in claim 1, including the step of storing an errors property associated with a particular component.

34. The method as recited in claim 1, including the step of storing a plurality of compound components.

35. The method as recited in claim 34, including the step of storing a members property associated with a particular compound component.

36. The method as recited in claim 1, including the step of storing a project component.

37. The method as recited in claim 1, including the step of storing a change list property associated with the project component.

38. The method as recited in claim 1, including the step of storing an error list property associated with the project component.
