Question on Application Architecture / Design Process

[Guest]

Hi,

I have a Business Requirements Document and Functional Spec from my customer
/ user.

How should I go about approaching the Database Design and Object Model
Design? Generally I have done this on an adhoc basis. What is the "correct"
or formal way of doing this?

Thanks.

How does your "adhoc" looks like?

Depends on methodology u use.
In general it's the ER diagrams for DB and class diagrams

I think you may find that "adhoc" might not sound like the correct way, but
in most cases it is the most practical.

I have found, with a customer request, getting the program running quick is
important. So adding what I need to into the database, on the fly, is not a
problem. Give the user a description of the new fields in the database so
they can run their reports off the database and know how they link up.

If a better solution is found later with different fields / a smarter way,
the change is made.

I guess you should ask yourself / your customer, - At what point does
documentation & Field / DB change Costs overcome the program $$$ savings
change.
