For your second question: For the architecture diagram, this is a higher level of abstraction. The ERD would fall in the data / domain layer. You'll have other layers as you've already identified, such as the Application, Domain, Business, and Interface layers.
Willem eprom programmer pcb50b software download. Latest Marvell driver (that I could see) is installed.I really need some advice on how to go about tackling an entity relationship diagram. I have to design one based on an application and have to show the cardinality and optionality of each relationship which I identify. I understand what this means and have looked over some examples on this but I am finding it hard to relate what I have got.
The entities which I have identified so far are: Client, Application, Reports, Interfaces
Also, what is the standard (if there is one) for representing Application, Business, Interface(s), etc. layers in a diagram?
