Workflow Builder :Work Flow builder is a Graphical interface to create and modify a business process with simple drag and drop operations.
It has two components –
* Navigator Window
* Process Window
A workflow builder would be used by a person to design and modify a workflow. It is more of a designer’s tool rather than an end-user’s tool.

Workflow Engine : The Workflow Engine embedded in the Oracle8 server monitors workflow states and coordinates the routing of activities for a process.Changes in workflow state, such as the completion of workflow activities, are signaled to the engine via a PL/SQL API or a Java API. Based on flexibly–defined workflow rules, the engine determines which activities are eligible to run, and then runs them. The Workflow Engine supports sophisticated workflow rules, including looping, branching,parallel flows, and sub-flows.

Workflow Definitions Loader :The Workflow Definitions Loader is a utility program that moves workflow definitions between database and corresponding flat file representations.It allows opening and saving workflow definitions in both a database and file.

Notification System : Each notification includes a message that contains all the information a user needs to make a decision.

Workflow Monitor : The Workflow Monitor displays an annotated view of the process diagram for a particular instance of a workflow process.Users can get a graphical depiction of their work item status. It also displays a separate status summary for the work item, the process, and each activity in the process.
