Abstract: In an object oriented computer system, a framework mechanism defines an infrastructure for allowing a user to flexibly define keys and their corresponding attributes. A special type of key called a specification key allows combinations of attributes to be specified, as well as set and range capabilities. An attribute retrieval policy is defined by a programmer to specify an algorithm or criteria that is used to calculating the desired attribute value. An attribute key controller contains key/value pairings for the attribute, contains the attribute retrieval policy, provides a maintenance interface for changing the attribute values; and provides a client interface for retrieving the attribute according to the attribute retrieval policy. The framework thus allows a user great flexibility in defining a suitable key/attribute retrieval mechanism by defining a suitable policy, defining one or more specification keys, and defining an associated controller.

Abstract: The present invention relates to a method of developing a software system using Object Oriented Technology and frameworks for developing a business application. The present invention solves this problem with a framework framework comprising a using non-financial component integration base class, a target financial component integration base class, and a generic data conversion engine. 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.
