Write a short paper describing the database underlying a small company enterprise system (e.g., Quickbooks® , Peachtree® , MYOB® , or another you have access to).
a. Does it appear to be integrated? When you change an item of data in one application, does it carry through to others? (For example, if a customer's billing address is changed, do all existing invoices reflect the change?)
b. How easy is it to set up the data relationships for the database?
c. Can you view the schema? Are subschemas supported?
d. Are there any controls in place to ensure that data relationships make sense? (For example, is referential integrity supported?)
