Case Study
Introduction
In this case
study we look at reports, which will show
you how to enhance your skills in using
Oracle Report Builder.
In these
Hands-On, your client is a stock broker that
keeps track of its customer stock
transactions. You have been assigned to
write them reports based on their reports
layout requirements.
Before using
the Report Builder tool
When you use
the Report Builder tool, there are few
modules that you may use them over and over.
They are basics for your understanding how
to use the tools.
Object
Navigator
In the Report
Builder tool, use the Object Navigator
window, to view report components and
navigate through the report objects. It
gives you a hierarchical listing of all the
modules open in your current session. You
use this listing to navigate to, and work
on, those objects. It gives you access to
all database objects you own or have grant
to, as well as a list of all the built-in
functions and procedures you can use in
Oracle Form Builder. Clicking on the plus
sign next to an object in the Object
Navigator will expand the object and
clicking on the minus sign will collapse the
object. Within the Object Navigator window,
you have:
� Reports
� Templates
� External SQL Queries
� PL/SQL Libraries
� Debug Actions
� Stack
� Built-in Packages
� Database Objects.
Reports Object
In the Reports
object, you have other important objects
that are very handy to create, delete, and
modify a report such as Live Pre-viewer,
Data Model, Layout Model, Parameter Form,
Report Triggers, Program Units, and Attached
Libraries.
� Live Pre-viewer
� Data Model
� Layout Model
� Parameter Form
� Report Triggers
� Program Units
� Attached Libraries
Live
Pre-viewer
You use the
Live Pre-viewer object to view what the
report will look like when it is executed.
Data Model
You use the
�Data Model� to display the data content and
layout appearance of the report. It�s very
important when you use this object that you
understand SQL statement and relationship
between tables such foreign key and primary
key.
Layout Model
You use the
Layout Model object to show you how your
report will appear. When you run your
report, Report Builder fills in the objects
in the Layout Model with actual data. The
Layout Model will show you several types of
layout objects and the relationships that
exist between them. The Layout Model uses
symbols and graphical representations to
show these relationships. You can add,
modify or delete part of your layout from
here.
Parameter Form
You use
Parameter Form to define, remove, and modify
your report parameters. You will use the �Parameter
Form Builder� tool to design your
runtime parameter form. There are two
types of parameters: user parameters and
system parameters.
User
Parameters
�User
parameters� will be used to manage the
behavior and output of your reports.
System
Parameters
�System
parameters� will be used to manage the
report runtime behavior of your reports such
as defining your output destination.
Remember that when you run your report, the
Runtime Parameter Form will be
appeared.
Report
Triggers
You use Report
Triggers to define PL/SQL to fire at various
points during the execution of your report.
You will have:
� BEFORE REPORT,
� AFTER REPORT,
� BETWEEN PAGES,
� BEFORE PARAMETER FORM, and
� AFTER PARAMETER FORM.
Program units
and Attached Libraries
You can use
Program Units and Attached Libraries as the
same way we use them in the Forms Builder
tool.
Property
Palette
In the course
of our hands-on, you will see that we use
Property Palette over and over. In fact you
can�t do much without Property Palette. It
is very important to understand it. It
contains object properties. The contents of
the Property Palette are referred to as the
�Property sheet� for the object. You use the
Property Palette to modify object
properties. To open the Property Palette of
an object, go to the object and right click
on the mouse then select Property Palette.
