The Component Oriented Design of Information Systems is spreading. After being used for gaining in reusability at the architectural
level, components are nowadays applied at the business logic level. We focus here on the design of multiple functional views
in such information systems, specially within the EJB framework. Traditionally, in the database context, this problem is solved
by the notion of “view-schemas” applied to a database schema. We present a composition-oriented approach grounded on the splitting
of entities according to views requirements. Two original design patterns are formulated and capture the main issues of the
approach. The first one is concerned with the management of the split component and its conceptual identity. The second offers
a solution for relationships among such components. Finally, we apply these patterns to the EJB framework. This framework
improves evolution and traceability of views.
