Hi All,

I have quick question regarding Business Domain model. I have read several times that we should not change the model
If we change we have to defend that change in assumptions section

I got an e-commerce application for part 2. There are 7 entities/boxes around the domain model is described which shows you the relationships.

Does this mean that we can have only these tables in my domain model (Database) ?

I think we have to preserve relations between the tables that are provided as part of the assignment, but we can add new tables to support the functionality and features of the application to be built.

A simple example for my e-commerce app, i would like to have a shipping, credit card and shopping cart tables.

Basic question does the word "change" mean that we cannot add new tables ?

Please advise.

thanks

You can add new tables/entities. Removing things is what is frowned upon because you could make the problem simpler.

In fact, it is likely you will need to add entities to flesh out a design.
