1.0 Document Purpose
The Low Level Design document models user interactions with the system we
are creating for Recreational Construction Incorporated (RCI) and how these
interactions are handled. This document contains sequence diagrams, which show the
interaction between objects, and a package diagram, which shows how classes are
related to one another.
Microsoft Visio 2007 was used to create all diagrams in this document.

2.0 Sequence Diagrams
Sequence diagrams provide details of object interactions, including messages
passed. They model the various use cases for the system. For example, in Figure 2.1,
the administrator or employee will enter a login in name and password into the login
screen, which is displayed on the user interface. From there, the name and password
are passed to the user handler, which will then access the database containing all user
names and passwords. If the login is successful, control is passed back to the
administrator or employee, and they are able to access the rest of the system. The
sequence diagrams are displayed in the following figures.
