It is worth spending a few moments on Terminology.
|•||Workspace - this is an Eclipse term and refers to a root folder in your file system where you will store your projects. When you install the Designer it creates a default Workspace called "workspace" for you.|
|•||Project - this is where you will create your Transformations. You can put one or more transformation "Graphs" into a single project.|
|•||Transformation - the general term for a set of operations that will manipulate your data.|
|•||Graph - this is the formal term for the graphical layout that contains a set of transformation components.|
|•||Transformation Components - these are the graphical objects that you will drag into your graph.|
|•||Edge - an edge is the line that joins components together.|
