In the previous chapters, we discussed the Informatica PowerCenter Designer screen in detail. This chapter marks the beginning of another client tool called Workflow Manager. Informatica PowerCenter Workflow Manager lets you execute the Informatica code. By now, you must be clear that we create a skeleton of the data flow in the mapping that contains the source for the target flow. Workflow Manager allows us to execute the mapping; in other words, we actually make the data flow from the source to the target when we execute the process called workflow in Workflow Manager.
Basically, Workflow Manager contains a set of instructions, which we define as a workflow. The basic building block of workflow is tasks. As we have multiple transformations in designer screen, we have multiple tasks in Workflow Manager screen. When you create a workflow, you add tasks to it as per your requirement and execute the workflow to see the status in the monitor.
As we discussed in Chapter 1, Starting the Development Phase – Using the Designer Screen Basics, the designer client screen is divided into five sections. Similar to this, Workflow Manager Screen is also divided into five sections called navigator, toolbar, workspace, output panel, and status bar. See Chapter 1, Starting the Development Phase – Using the Designer Screen Basics for a detailed description.
Informatica PowerCenter Workflow Manager has the following tools that you can use to create and execute workflows and tasks:
The tools are as follows:
- Task Developer: Using this component, you can create different types of tasks that you wish to add to your workflow. The tasks created in Task Developer are reusable tasks.
- Worklet Designer: A group of reusable tasks is defined as Worklet. You can create Worklet on Worklet Designer.
- Workflow Designer: A workflow can be created in Workflow Designer. Add different tasks to the workflow by connecting links.
