Framework for software development

摘要

The invention relates to a framework being used for developing software system e.g. for a business application. This framework includes a number of object oriented classes which may be processed by a computer system. The invention provides an interface and a base class which implements this interface that allows specific data to be added to the objects of classes supporting the interface at runtime without the need for subclassing of the original class. Specific data added in this way to an object are referred to as properties of the object, and the interface introduced by this invention is referred to as the property container interface. The present invention is applicable in the techniclal 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. <IMAGE>
