App Studio includes sample data and Master Files to help familiarize you with the interface and practice creating applications. However, to create applications that report on your own data, you need to create Master Files (.mas) and Access Files (.acx).
Master Files describe the data so that WebFOCUS can report on it. Access Files provide information that WebFOCUS needs to access the data. Together, the collection of Master Files and Access Files for a specific data source is called a synonym.
This topic provides information on how you can create synonyms to report on your own data.
