Explanation
An important use of a dependency relationship is to represent compilation dependencies. A compilation
dependency exists from one element to the elements that are needed to compile it. In C++, for example, the
compilation dependencies are indicated with #include statements. In Ada, compilation dependencies are
indicated by the with clause. In Java the compilation dependency is indicated by the import statement. In
general there should be no cyclical compilation dependencies.
Example 1:
The following component diagram illustrates compilation dependencies between source files. The Invoicing_UI
file (the top), requires Invoice, which requires Order to compile.
