[snip] and a half

I cannot help you with your specific problem because I am unable to
compile (let alone read) your code. From what I can discern, I have the
following advice:

Rethink your design. For starters, you need more than 2 classes because
you have more than 2 distinct concepts. Also, the inheritance between
BankDB and BankAccount does not make sense. Generally, an inheritance
would imply an is_a relationship. i.e., if class C inherits from class B
then C is a B.

One thing you might want to do as an exercise is to come up with a
BankAccount class that has only what it needs... nothing else. Do the
same for the other 'objects' in your program. When you have each
object's interface written down, then work on how they interact with
each other. What I often do is create the class with only data and
constructors. Once all my classes are written this way, I start trying
to use them in a program. The interface (public methods) almost writes
itself.

When you are to the point of implementing your new design, ask here
about any specific problems you have with the code. You should read the
faq
     http://snurse-l.org/acllc-c++/faq

before you do because that can also give you ideas on how to solve your
problems.
