How to realize extendable data objects? 2003-09-23 - By Udo Cirkel

Hi all,
i have a question belonging to the realization of data objects.
Which approach or pattern is appropriate to solve the following problem:
- We are developing a supply chain management application that has to be
devided and delivered in modules.
Depending on the business requirements of a customer an installation can
embrace different modules.
A modules realizes a set of functionality like production planning, stock
management, controlling, ...
- The data object "material" plays a central role in the application under
discussion.
The "material" class has a lot of attributes (e.g. description, value,
safety stock, delivery time, ...).
Theses attributes are used by serveral application modules.
- The application must be extendable, so that new functionalities (modules)
can be added in future without
changing the existing modules.
=> How can we realize a data object - e.g. "material" - that has a set of
initial attributes and
that can be automatically extended in future (adding new attributes) by
deploying new modules ???
Does there exist an appropriate pattern for this problem?
Can i solve it using ejbs or daos?
Any suggestions are welcomed.
Bye,
Udo
