Concepts

A master/master report displays at least two sets of data that are not directly related—that is, the records constituting the data are fetched using at least two separate queries. A master/master report (also called a parent/parent report) contains two or more queries with no links (parent/child relationships).

Data Relationships

Although the data may be conceptually related, the queries make no attempt to relate it by the manner in which it is fetched. To select the data for a master/master report, you create two or more unrelated queries. Reports Builder will create all other necessary data objects by default.

Layout

This report uses the default tabular layout style. You will move the layout objects associated with the second query to insert more space between the information fetched by the two queries and make your report easier to read.

Example Scenario

To see a sample master/master report, open the examples folder named masterb, then open the Oracle Reports example named masterb.rdf. For details on how to access it, see "Accessing the Example Reports" in the Preface.
