Example 1: Creating the job. Create the example job that includes one Hierarchical Data stage and two Sequential File stages. Example 1: Opening the Assembly Editor and viewing the issues. For each Hierarchical Data stage, you open the Assembly Editor, which you use to define an XML transformation within the context of a job. Creating XML Files Using Hierarchical Stage in IBM Datastage. XML files, being the most popular way for data transportation, could be the most sought ought way by many clients for moving the data around. Hence, it becomes inevitable for one to know how to create/parse/transform XML files . Using XML Output. You can convert tabular data, such as relational tables and sequential files, to XML hierarchical structures, using the XML Output stage. XML Output supports a single input link and zero or one output link. About transforming tabular data. Validating . Apr 21,  · In order to use the XML stage, we need to have XSD (XML Schema definition) File. We should get the XSD from the corresponding source system. You may generate XSD in case you don't get one from source system but this is risky option because XML you use may not have all the tags required to be there in inbetatest.website: Suhel Mukardamwala. XML documents are meant to be processed in their entirety by the XML Input stage within a DataStage job. The traditional method of using a sequential file stage to access a file is designed to parse the file into records and columns. This is problematic for XML documents which are hierarchical data structures and are not organized in tabular form.

This chapter does not discuss all the features available for DataStage Designer. The DataStage Designer is the primary interface to the metadata repository and provides a graphical user interface that enables you to view, edit, and assemble DataStage objects from the repository needed to create an ETL job.

An ETL job should include source and target stages. Additionally, your server job can include transformation stages for data filtering, data validation, data aggregation, data calculations, data splitting for multiple outputs, and usage of user-defined variables or parameters. These stages allow the job design to be more flexible and reusable. The DataStage Designer window, which is the graphical user interface used to view, configure, and assemble DataStage objects, contains the following components:.

Repository Window: Displays project objects organized into categories. By default, the Repository window is located in the upper left corner of the Designer window. The project tree displays in this pane and contains the repository objects belonging to a project.

Tool Palette: Contains objects that you add to your job design, such as stage types, file types, database types, and processor objects.

You can drag these objects from the Palette into the Diagram window. By default, this window is displayed in the lower left corner, of the Designer window. This window appears to be empty until you open or create a job. Diagram Window: Serves as the canvas for your job design.

You drag, drop, and link stages and processor objects to create jobs, sequencers, and templates. Property Browser: Displays the properties of the currently selected stage of the job that is open in the Diagram window. By default, this window is hidden. To open it, select View, Property Browser from the menu bar, and then click a stage to see its properties.

The display area is in the right pane of the DataStage Designer window and displays the contents of a chosen object in the project tree. The display of Designer windows and toolbars can be shown or hidden by selecting the appropriate option from the View menu. You can dock, undock, or rearrange the Designer windows. Most Designer menu items are also available in the toolbars. The following are some additional options that are available through the menus:.

Enables you to import ETL projects, jobs, or other components that you export from another system, as well as DataStage components, such as table definitions, from text files or XML documents.

Enables you to export DataStage objects in the form of text files with the file extension. Display the Open window that enables you to open an existing or recently opened repository object. Use this function to display the data lineage for a column definition to see where in the job design that the column definition is used, display the source of the data for selected column or columns, display the target for the data for selected column or columns.

Show or hide annotations in the diagram window. You enter annotations by dragging the Annotation object from the Palette. See visual cues for parallel jobs or parallel-shared containers. The visual cues display compilation errors for every stage on the canvas, without you having to actually compile the job. The option is enabled by default. When the grid is shown and Snap to Grid is enabled, align objects that you drag with the grid. Generate an HTML report of a server, parallel, or mainframe job or shared container.

You can view this report in a standard Internet browser. You can use DataStage Designer to view job categories, which serve to organize repository objects. You can also copy, rename, edit, delete, or move an item using the File menu commands or the item level shortcut menu. Object properties consist of descriptive information and other types of information, depending on the object type.

Editing Server Routines You can create, edit, or view server routines using the Routine window. Argument names in built-in routines cannot be changed. The Stage Type category in the project tree contains all the stage types that you can use in your jobs. Properties of WebSphere DataStage's pre-built stages are read-only. DataStage Designer enables you to create and register plug-in stages to perform specific tasks that the built-in stages do not support.

You need to register custom plug-in stages before you can use them. In addition, DataStage Designer enables you to create custom parallel stage types. Using the DataStage Designer import and export facilities enable you to move jobs or other components between projects. You can also move projects, jobs, or components from one system to another. XML documents can be used as a convenient way to view descriptions of repository objects using a web browser.

When you export projects or components, by default they are stored in text files with the file extension. You can also export to XML files by selecting the appropriate check box in the Export window. You also have the option to append the exported items to an existing file. Using Table Definitions Table definitions are:. You need a table definition for each data source stage or data target stage you use in your job. You can import, create, or edit a table definition using DataStage Designer.

The Table Definition window appears:. The General tab contains the data source type, data source name, table or file name, and other general information about the table definition. The Columns tab contains a grid displaying the column definitions for each field in the table definition. The Relationships tab displays the details of any relationship this table definition has with other tables, and allows you to define new relationships.

Using the Locator tab you can view and edit the data resource locator associated with the table definition. The data resource locator is a property of the table definition that describes the real world object from which the table definition was imported.

The labels and contents of the fields in this window depend on the type of data source or target from which the locator originates. The Analytical Information tab displays information about the table definition generated by Information Analyzer.

The Parallel tab displays detailed format information for the defined metadata for parallel jobs. You can directly import a table definition from a source or target database. Mainframe Jobs: Available only if you have installed Enterprise MVS Edition and uploaded it to a mainframe, where they are compiled and run.

Edit source and target stages to designate data sources, table definitions, file names, and so on. Edit transformer and processing stages to perform various functions, include filters, create lookups, and use expressions. In the General tab, you define the source database type, database or connection name, user ID, and password used in that connection. The previous example uses environment variables to define the values of these fields.

If environment variables or job parameters were not used in the DRS stage, you define the actual values in these fields. In this example, the table name listed is the source of the data that this stage uses. The Columns window shown below enables you to select which columns of data you want to pass through to the next stage. When you click the Load button, the system queries the source table and populates the grid with all the column names and properties. You can then delete rows that are not needed.

It is read-only. Enter optional SQL statements executed before the stage processes job data rows. This does not appear in every plug-in. Enter optional SQL statements executed after the stage processes job data rows This does not appear in every plug-in. It allows you to design jobs that run on SMP systems with great performance benefits. Pivot, an active stage, maps sets of columns in an input table to a single column in an output table.

Creating Transformer Stages. You create a transformer stage by opening the Processing group in the palette, selecting the Transformer stage, and clicking in the Diagram window. After creating links to connect the transformer to a minimum of two other stages the input and output stages , double-click the Transformer icon to open the Transformer window.

In the example above, two boxes are shown in the upper area of the window representing two links. Transformer stages can have any number of links with a minimum of two. Hence, there could be any number of boxes in the upper area of the window. Labeling your links appropriately makes it easier for you to work in the Transformer Stage window. The lines that connect the links define how the data flows between them.

When you first create a new transformer, you link it to other stages, and then open it for editing. There will not be any lines connecting the Link boxes. These connections can be created manually by clicking and dragging from a particular column of one link to a column in another link, or by selecting the Column Auto-Match button on the toolbar. This table describes the buttons provided with the Transformer Stage toolbar. Define order in which input and output links are processed if there is more than one input or output link.

Enter a condition that filters incoming data, allowing only the rows that meet the constraint criteria to flow to the next stage. If you have more than two links in the transformer, you can select one link and click this button to hide all connection lines except for those on the selected link. With only two links present, clicking this button hides or displays all connections. Show or hide a box that displays local stage variables that can be assigned values in expressions, or be used in expressions.

Save a column definition in the repository so that it can be used in other stages and jobs. Automatically sets columns on an output link to be derived from matching columns on an input link.
