Ray Ells’ software consultancy has been awarded a contract to develop Casebook, a SaaS app to keep track of the status of civil court cases. Here are some notes from an early customer interview:Each case has two parties: the plaintiff and the defendant.The same plaintiffs and defendants may be parties in more than one case. A party that is a plaintiff in one case might be a defendant in another case.Each case is assigned to exactly one judge and its proceedings administered by exactly one court clerk. Every court officer is either a judge or a court clerk.The only people who can login to the app and access the data are court officers. Login should be required for all app actions, that is, the only publicly-viewable page should be the login page.A case has a variable number of supporting documents associated with it. Examples of documents include motions, depositions, evidence (photographs, scanned documents, audio or video clips, etc.), and others.
