net: business entity?

Question

hi all I would like to know that what considerations we need to do when designing business entities as a software architect?

Any reference or help is appreciated.

Answer 1

Its a very broad question but some high level topics that i think you must look at include:-

Concurrency - how your objects will handle it

Caching of Business objects and how it will be done.

Persistence / Retrival of business objects - If you use will use an ORM - Decision as to what ORM best fits your needs

Business rules validation and how it will work

Parent-child relationship management

N-level undo

Databinding Support

Transactions Support

Serialization of the business objects

Utilities like cloning (deep copy) of objects

In addition, there will be various patterns that you need to consider based on what suits your requirements best

1. What kind of responsibility pattern will they have. Eg: Expert Business objects
2. Will the objects incorporate patterns like lazy loading their data or not.

I think it would be good to explore some ORM like NHibernate or business object framework like Rockford Lhotka's CSLA as a starting point.

This should give you a pretty fair starting point and even help you decide if these frameworks meet your specific needs or you need something else.
