In this chapter you ll look at Quadrant a modeling tool that addresses a wide range of tasks including creating maintaining and editing models and data in the Repository or in other SQL database tables as well as writing and editing M code. Quadrant is a powerful tool in terms of its functionality and it has an extensive feature set. I could begin with a walkthrough each of the features in its menu tree but that may not be the most interesting or productive way of getting the first-time user up to speed. A tool with an extensive feature set can be a bit overwhelming for the new user so this chapter will approach its subject at a somewhat higher level. The intent here is to give you an overview of Quadrant without immersing you in too many of the details. Appendix D shows the Quadrant menu tree so feel free to refer to that any time you would like to see where a particular feature fits. My Car Creating a Simple Model in Quadrant You ll start putting Quadrant through its paces by creating a simple systems model of a car. As you know you can analyze many complex systems like planes trains and automobiles as a composition of different levels of subsystems and components. In addition the subsystems themselves can be further analyzed into lower level subsystems. This is a partitioning design pattern usually referred to as the composite pattern.
