We just finished creating a set of videos showing how to create master/detail reports in our soon-to-be-released components Report Workshop. Several videos showing how to create two level reports using different ways, and a video showing how to create a complex report (linked to this post).

All these videos use SQL (a basic knowledge of SQL, at the level select A from B where C = D group by E, is needed). There are other ways to make master/detail reports (using TDataSetField, or using a relation between data sets established in an application) that are not shown.
