Do Not Use Database Tools to Modify Oracle Applications Data
Oracle STRONGLY RECOMMENDS that you never use SQL*Plus,
Oracle Data Browser, database triggers, or any other tool to modify
Oracle Applications data unless otherwise instructed.
Oracle provides powerful tools you can use to create, store, change,
retrieve, and maintain information in an Oracle Database. But if you
use Oracle tools such as SQL*Plus to modify Oracle Applications data,
you risk destroying the integrity of your data and you lose the ability to
audit changes to your data.
Because Oracle Applications tables are interrelated, any change you
make using Oracle Applications can update many tables at once. But
when you modify Oracle Applications data using anything other than
Oracle Applications, you may change a row in one table without
making corresponding changes in related tables. If your tables get out
of synchronization with each other, you risk retrieving erroneous
information and you risk unpredictable results throughout Oracle
Applications.
When you use Oracle Applications to modify your data, Oracle
Applications automatically checks that your changes are valid. Oracle
Applications also keeps track of who changes information. If you enter
information into database tables using database tools, you may store

1 – 1Overview of Oracle Workflow
Overview of Oracle
Workflow
his chapter introduces you to the concept of a workflow process
and to the major features of Oracle Workflow.
1 – 2 Oracle Workflow Developer’s Guide
Overview of Oracle Workflow for Developers
Oracle Workflow delivers a complete workflow management system
that supports business process based integration. Its technology enables
modeling, automation, and continuous improvement of business
processes, routing information of any type according to user–defined
business rules.
E–business is accelerating the demand for integration of applications
within the enterprise as well as integration of a company’s systems with
trading partners and business–to–business exchanges. Oracle Workflow
automates and streamlines business processes both within and beyond
your enterprise, supporting traditional applications based workflow as
well as e–business integration workflow. Oracle Workflow is unique in
providing a workflow solution for both internal processes and business
process coordination between applications.
Routing Information
Business processes today involve getting many types of information to
multiple people according to rules that are constantly changing. With so

system to another when business events occur. You can communicate
events among systems within your own enterprise and with external
systems as well. In this way, you can implement point–to–point
messaging integration or use Oracle Workflow as a messaging hub for
more complex system integration scenarios. You can model business
processes that include complex routing and processing rules to handle
events powerfully and flexibly.
Major Features and Definitions
Oracle Workflow Builder
Oracle Workflow Builder is a graphical tool that lets you create, view, or
modify a business process with simple drag and drop operations. Using
the Workflow Builder, you can create and modify all workflow objects,
including activities, item types, and messages. See: Workflow Processes:
page 1 – 6.
At any time you can add, remove, or change workflow activities, or set
up new prerequisite relationships among activities. You can easily work
with a summary–level model of your workflow, expanding activities
within the workflow as needed to greater levels of detail. And, you can
operate Oracle Workflow Builder from a desktop PC or from a
disconnected laptop PC.
Workflow Engine
The Workflow Engine embedded in the Oracle Database implements
process definitions at runtime. The Workflow Engine monitors
workflow states and coordinates the routing of activities for a process.
