1. ORACLE FORMS 6I
• Enterprise application developers need a declarative model-based approach. Oracle Designer
and Oracle Forms Developer provide this solution, using Oracle Forms Services as the primary
deployment option.
What Is Oracle Forms Developer?
• A productive development environment for Internet business applications
 Data entry
 Query screens
• It provides a set of tools that enable business developers to easily and quickly construct
 sophisticated database forms and
 business logic with a minimum of effort.
Oracle Forms Services?
 Oracle Forms Services is a component of Oracle9i Application Server for delivering
Oracle Forms Developer applications to the Internet.
 Oracle Forms Services uses a three-tier architecture to deploy database applications:
1. The client tier contains the Web browser, where the application is
displayed and used.
2. The middle tier is the application server, where the application logic and
server software reside.
3. The database tier is the database server, where enterprise data is stored.

2. What is Form Builder?
Form Builder is a powerful development tool for building robust, enterprise-class applications that
enable end users to retrieve, enter, modify, and save information in the database.

4. Form Builder Components

5. 1. Object Navigator – [F3]
2. Property Palette [F4]
3. Layout Editor (or Layout Model) [F2]
4. PL/SQL Editor [F11]
Types of Blocks
In Form Builder there are two main types of blocks:
1. data blocks and
2. control blocks.
1. DATA BLOCKS
• A data block is associated with a specific database table (or
view), a stored procedure, a FROM clause query, or transactional triggers.
• If it is based on a table (or view), the data block can be based on only one base table
2. Control Blocks
• A control block is not associated with a database, and its items do
not relate to any columns within any database table.
• Its items are called control items.
What Is a Window?
A window is a container for all visual objects that make up a Form Builder application.
It is similar to an empty picture frame.
What Is a Canvas?
A canvas is a surface inside a window container on which you place visual objects
such as interface items and graphics.
What Is a Content Canvas?
A content canvas is the base canvas
that occupies the entire content pane of the window in which it displays. The content
canvas is the default canvas type.
Form Builder provides three other types of canvases
which are:
• Stacked canvas
• Toolbar canvas
• Tab canvas
When you create a canvas, you specify its type by setting the Canvas Type property.

6. The type determines how the canvas is displayed in the window to which it is
assigned.
What Is a Stacked Canvas?
A stacked canvas is displayed on top of, or stacked on, the content canvas assigned to
a window.
What Is a Toolbar Canvas?
A toolbar canvas is a special type of canvas that you can create to hold buttons and
other frequently used GUI elements.
The Three Toolbar Types
• Vertical toolbar: Use a vertical toolbar to position all your tool items
down the left or right hand side of your window.
• Horizontal toolbar: Use a horizontal toolbar to position all your tool
items and controls across the top or bottom of your window.
• MDI toolbar: Use an MDI toolbar to avoid creating more than one
toolbar for a Form Builder application that uses multiple windows.
What Is a Tab Canvas?
A tab canvas is a special type of canvas that enables you to organize and display
related information on separate tabs.
