• Chapter 25, "Building a Matrix Report"

  A matrix report looks like a grid that contains a row of labels, a column of labels, and information in a grid format related to both the row and column labels. These reports are sometimes referred to as "crosstab" reports.

• Chapter 26, "Building a Nested Matrix Report"

  A nested matrix report contains the cross product, that displays every possible value for three dimensions - two down (such as YEAR and DEPTNO) and one across (such as JOB).

• Chapter 27, "Building a Matrix with Group Above Report"

  A matrix with group above report is a combination of a matrix layout and a group above layout. For each group in this report, the break group (e.g., the department number) displays across the top of the record, and the details of the group (e.g., the employee information) displays in a matrix format.
