Research the functionality of the three layers (presentation, domain, and data source) of enterprise application software. Write a paper describing each layer in detail as it would apply to a specific type of enterprise application software (you select the specific type of software to use in your examples, be consistent and use the same type of enterprise application software through your entire paper). Be sure to introduce the type of enterprise application software you have selected to use as an example. Point out areas that could be problematic in the development cycle for the specific example that you have selected as well as solutions that you deem appropriate.
