Report Styles
A tabular report is the most basic
type of report. Each column
corresponds to a column selected
from the database.
A form-like report displays
one record per page,
inserting field values to the
right of field labels.
A mailing label report prints
mailing labels in multiple
columns on each page.
You can print the labels
across the page and then
down, or down and then
across.
A form letter report contains database
values embedded in boilerplate text.
(Boilerplate text is any text that you
enter or import into a Report Editor.)

A group left report divides the rows of a table into "sets," based on a
common value in one of the columns. Use this type of report to restrict a
column from repeating the same value several times while values of
related columns change.
A group above report contains two or more
groups of data. For every value of the
master group, the related values of the
detail group(s) are fetched from the
database.
A matrix (cross-tabulation) report
contains one row of labels, one
column of labels, and information in
a grid format that is related to the
row and column labels. A
distinguishing feature of matrix
reports is that the number of
columns is not known until the data
is R.fetched
from the database.

A matrix with group report is a group
above report with a separate matrix
for each value of the master group.

SQL
R. Ching, Ph.D. • MIS Area • California State University, Sacramento
Data Model Objects
• Component objects:
– Queries
• SQL statements
– Links
• Establishes the relationship between the data of two
queries (e.g., master/detail)
– Groups
• Similar to control groups in control break reports
– Columns
• Data on the report (vertical arrangement)
• Summary, formulas or placeholders
