Problem

You would like to put a component approach to work, in accordance with Herzum & Sims, for the constitution of a global framework of reusable business components.

Process

• Analysis:
  - defining the business model's classes
  - retrieving existing components (COM, CORBA, EJB)
  - reverse engineering existing applications in order to obtain a complete UML analysis model
• Discovering components through use cases and activity diagrams
• Grouping components as Process Business Components, Entity Business Components or Utility Business Components
• Market study to locate off -the-shelf components
• Applying general principles: n-tier, GUI independence with regard to the application, thin clients, ...
• Choosing a implementation framework (EJBs, CORBA, .Net, ...) and a language (C++ , Java, C#, ...)
• Automatic code generation for Java, EJBs, C++, IDL Corba, SQL, ...
• Putting a component assembly method and associated tools to work

Benefits

• Creation of a set of durable components, adapted to the business
• Putting in place of a methodology for the creation of components and their assembly within the applications' framework
