This paper presents a Component-based Framework Development Process, of the Cardiology Domain. The Framework, called FrameCardio, was developed in 4 steps: 1Problem Domain Definition, 2-Components Specifications, 3-Components Internal Design and 4-Components Implementation. In the first step the framework requirements were identified, based on experiences in the development of a cardiology system with 320 classes. The main models specified in this step are the Use Cases, Actions and Collaborations Models. In the Component Specification step component external behaviors were defined with their responsibilities, operations and interfaces. The main models are the Types Model, that describes an object external behavior, regardless of implementation decisions, and the Component Interactions that details the behavior of each case used in the Sequence Diagrams. Right after, in the third step, the Specified Components are refined, considering the implementation technologies. Among the models ...
