The last and most important aspect that you learned in this chapter was how to create mappings using sources and targets. Later in the chapter, you saw how to preview the data. We also worked on the import and create functionalities of sources and targets. Similarly, we worked on different types of targets. You then learned to work on different types of sources, which included flat files (delimited files and fixed-width files) and relational databases. We started the chapter with the basic components of the PowerCenter Designer screen, that is, Source Analyzer, Target Designer, Transformation Developer, Mapplet Designer, and Mapping Designer. Navigate to Repository | Save to save the changes to the repository. Some personal details and reference details can be saved. You can store some metadata related to the target you created. You can add, delete, or edit the columns.Д¬lick on the Metadata Extensions tab usually, you keep this tab blank. This will display the column descriptions for the target. Usually, we keep the Business name section empty.Д¬lick on the Columns tab. You can add a comment in the Description section. The Table tab will show the name of the table, the owner name, and the database type. This will open the T_EMPLOYEES target definition.ДЄ pop-up window will display all the properties of this target definition. Select the type of target you wish to create from the drop-down list.ДЄn empty target structure will appear in the Target Designer.Дouble-click on the title bar of the target definition for the T_EMPLOYEES table. In the designer screen, navigate to Tools | Target Designer to open the Target Designer. The following screenshot shows the Source Analyzer screen components: You can add multiple sources, multiple targets, and multiple transformations in a mapping. Mappings contain sources, targets, and transformations linked to each other through links. Mapping Designer: This allows you to create mappings that the Integration Service uses to extract, transform, and load data. Mapplets are groups of reusable transformations that can be used in multiple mappings as reusable components. Mapplet Designer: This allows you to create a group of transformations to use in mappings. Reusable components are important because they allow you to use the existing transformations. Transformation Developer: This allows you to create reusable transformations to use in mappings. Target Designer lets you modify the existing target definitions. You can work on various types of files (flat files, XML. Target Designer: This allows you to import or create target definitions. Source Analyzer lets you modify the existing source definitions.

Source Analyzer: This allows you to import or create source definitions. The preceding screen components are shown in the following screenshot: The status bar shows you the status of the operation that you are trying to perform. Status bar: This displays the status of the current operation.

If invalid, the output panel shows you the reason for the error.

You can view whether your code is valid or invalid. Output/control panel: This lets you view details about tasks you perform, such as saving your work or validating a mapping. Toolbar: This shows the various components to be used in the designer screen and other shortcuts. In the designer workspace, you can see different tabs, such as Source Analyzer, Target Designer, Transformation Developer, Mapplet Designer, and Mapping Designer. Open different tools in this window to create and edit the repository objects, such as sources, targets, mapplets, transformations, and mappings. Workspace: This is the space where you actually do the coding. Navigator allows you to reuse the existing components. You can copy objects and create shortcuts within the navigator. In the Education section, write about your formal education - namely, your Bachelor and Masters degrees.Navigator: This is used to connect to repositories and open folders. It is a good idea to put Relevant completed online courses on your resume, especially if you have a certificate for it. In this way, we can cop up with different types of field in the same and can expand our knowledge at a better extent. Online courses are sometimes better than the traditional course and even better when both of them work parallel. Yes, it is possible to get a job using online courses. Through this method, professors can tell whether or not the same student is typing during a test. The most effective way to catch a cheater includes proctored exams. Online universities and massive open online courses use a variety of tools to deter students from cheating.
