Preparing your system for Compose
Compose should be installed on a Windows Server machine that is able to access the data warehouse and optionally the source database(s) defined in your Compose project. Note that Compose only needs to access the source database if you plan to discover the source database when generating your model. For more information on discovery, see Discovering the Source Database or Landing Zone.
Before installing Compose, make sure that the following prerequisites have been met:
