Creating a New Data Layer

Follow the steps below to create a new Data Layer in a Graphmart.

For instructions on creating a new layer by copying an existing one, see Cloning an Existing Data Layer.
  1. In the Anzo application, expand the Blend menu and click Graphmarts. Anzo displays a list of the existing Graphmarts. For example:

  2. Click the name of the Graphmart that you want to add a Data Layer to. The Overview tab is displayed. For example:

  3. Click the Data Layers tab. Anzo displays the existing data layers. For example:

  4. Click Add Layer and select New Layer. Anzo displays the Create dialog box.

  5. Specify a name for the layer in the Title field and an optional description in the Description field.
  6. Determine how you want to control changes to this Data Layer's dependent Data Models:
    • If you want Anzo to automatically deploy to AnzoGraph any changes to the related models without having to manually refresh the layer or Graphmart, select the Auto Deploy Ontology Changes checkbox.

      The Manual Refresh Graphmart setting on the Graphmart must be disabled for automatic deployment of models to work. See Creating a New Graphmart for information about Graphmart settings.

    • If you want Model changes to be deployed to AnzoGraph only when this Data Layer (or entire Graphmart) is manually refreshed or reloaded, leave the Auto Deploy Ontology Changes checkbox empty (disabled).
  7. Determine whether to Disable Loading Counts for this Data Layer. This setting controls whether Anzo periodically sends COUNT queries to AnzoGraph while this layer is reloading or refreshing. Disabling the load counts may increase load performance as it decreases the number of queries that during data loads.
  8. Click Save to add the new layer to the Graphmart and return to the Data Layers screen.

The new layer becomes the last layer in the Graphmart. For example, the image below shows a new layer called Employees:

If you want to change the order of the layers, you can click the black bar on the left side of a layer and drag the layer up or down. Data Layers are processed from top to bottom.

The Refresh icon () on the new layer indicates that the layer is out of sync with the data that is in AnzoGraph. Once you configure the new layer and add data processing steps, you can click the Reload button () at the top of the screen to reload the entire Graphmart, or you can click the Refresh icon () on the layer to reload only that layer.

Next, proceed to Configuring Data Layers if you want to configure options such as Execution Conditions and Masking for the Layer. See Adding Steps and Views to Data Layers instructions on creating Steps.
