Dataset Flow

The Dataset Flow graph shows the data flow within a batch process, starting from a physical dataset. The starting dataset can be at the start of the process (forward data flow), at the end of the data flow (backward data flow) or in the middle of it (backward and forward data flow).

To display the Dataset Flow graph, in Application Discovery Browser perspective, from the Projects list in the central part of the Explore Projects view, select the project that contains the resource for which you want to generate a Dataset Flow graph. For details on perspectives and their components, see IBM® AD Analyze Client Reference.

In the Mainframe Graphs section to the right of the Explore Projects view double-click Dataset Flow to display the Data Flow Through Physical Dataset Analysis wizard.

The Available Datasets area displays the datasets available for graph generation. Use the Name field to filter the contents of the list. Use the arrow buttons to move the datasets between the Available and Selected lists. By default, the graph analysis depth is not limited and the direction of the analysis is forward. Modify according to needs then click Next to display the second dialog window of the wizard.

Select the datasets for which the subsequent tree must be excluded from the graph. The "excluded" datasets are displayed in the graph with a funnel icon that indicates that the subsequent tree was excluded from the graph. Then, press Finish to generate the graph.

AD Graphs tab displays the generated graph. To navigate the graph, use the buttons in the graph toolbar. For details, see Graphical Analysis Toolbar. To show details on the meaning of the elements of the graph, use the Legend button. For details on the graph legend, see Showing the Graph Legend.

By default, a limit icon marks a node beyond which further analysis results are not displayed because of the limit set in the wizard. (highlight results that are cut short by the threshold option checked in Analysis Expansion Limit tab from Preferences window). If highlight results… option is not checked, all nodes that reach the level limit set in the wizard are marked with a limit icon regardless of whether further analysis results are available or not. The same criteria apply for displaying the limit icon in the Graph Inventory window.

AD Graph Overview window presents an overview of the entire graph, which can be useful when you work with large graphs. For details, see AD Graph Overview Window.

AD Graph Inventory pane presents a list of all the elements in the graph. For details, see AD Graph Inventory View.

The Properties window displays the properties of the element that is selected from the graph. For details, see Properties View.

Use Export Graph and Print (from the Eclipse toolbar) to export the graph to a portable format or print it. For details, see the sections Exporting the Graph and Printing the Graph.

Dataset Flow graph element pop-up menu

Right-click on an element from the dataset flow graph to display the pop-up menu.

The options available in the pop-up menu depend on the type of element that selected from the graph. Options available for all element types include View analysis source, Show properties, and Filter.

According to the selected element, some or all of the following options might also be available: Annotations, Reports, and Usage analyses.

The Filter options in the pop-up menu allow the user to toggle on/off different elements of the graph.

For details on the options available for all element types, see Graph element pop-up menu.
