XEO Library - Introduction

In this chapter we'll introduce a sample application, The XEO Library, which we'll use to go more in depth in the various XEO Concepts vaguely described up until now.

The XEO Library is an application to help manage a library with its target users being the librarians who work there, whom must register the books users take home to read and also register when they return the books. Librarians are also responsible for creating user accounts (the equivalent of giving them a Library Identity Card) and managing all the information about the books (including their titles, authors, publishers, etc...). Librarians also have a private messaging system so that they can send notifications to each other. Figure LibIntr.1 depicts the set of actions Users and Librarians can do in out library (as explained before)
