Abstract

The present invention relates to a method of developing a software system using Object Oriented Technology. The present invention addresses the problem of providing a technical foundation for the development of software applications using Object Oriented Technology and frameworks. The present invention solves this problem with a framework allowing the modeling of businesses with a multiple level organizational structure. The present invention is applicable in the technical field of application development of software systems, e.g. for a business application as Financial or Logistic and Distribution, wherein it is the purpose of frameworks to provide significant portions of the application that are common across multiple implementations of the application in a general manner, easy to extend for specific implementation.

Claims

1. A computer-implemented framework mechanism of object-oriented technology for developing application software in a computer system, said framework comprising:

a plurality of business objects organized in a tree structure, wherein said business objects represent an organizational structure; and

a first controller, for controlling a first group of said plurality business objects including as a property said first controller;

said first controller having associated with it a parent controller, said parent controller controlling a second group of business objects including as a property said parent controller;

said first controller providing access, by object name, to said first and second groups of business objects in response to a client instantiation of a named object.

2. The framework according to claim 1, wherein:

said first controller comprises an aggregating controller and said parent controller comprises one of a root controller and an aggregating controller.

3. The framework according to claim 1, wherein a controller class including said first controller and said parent controller provides an interface for said client to access, delete or create objects of a business object class represented by a business object within said first and second groups of business objects.

4. The framework according to claim 1, wherein said first controller and said parent controller occupying different hierarchical levels within said tree structure.

5. The framework according to claim 1, wherein said first controller exhibits a hiding behavior, said hiding behavior selectively preventing instances of named objects within said first and second groups of business objects from being provided to said client.

6. The framework according to claim 5, wherein in the case of an instance of a business object included within both of said first and second groups of business objects, only a local named business object is provided to said client.

7. The framework according to claim 6 wherein said local business object comprises the named business object within said first group of business objects.

8. A computer-implemented framework mechanism of object-oriented technology for developing application software in a computer system, said framework comprising:

a plurality of business objects organized in a tree structure, wherein said business objects represent an organizational structure; and

an aggregating controller, for controlling a first group of said plurality business objects including as a property said aggregating controller;

said aggregating controller having associated with it a parent controller, said parent controller controlling a second group of business objects including as a property said parent controller;

said aggregating controller providing access, by object name, to said first and second groups of business objects in response to a client instantiation of a named object; and

said aggregating controller and said parent controller occupying different hierarchical levels within said tree structure.

9. The framework according to claim 8, wherein said aggregating controller exhibits a hiding behavior, said hiding behavior selectively preventing instances of named objects within said first and second groups of business objects from being provided to said client.
