Introduction 

The most common method for populating a repository is to use the Generate Parameterized Messages wizard when creating a virtual asset, but you can also structure and populate a data repository with Excel, WSDL, or schema files using the Data Repository Tool. The Data Repository Tool specifies the data to import, how to structure it, and which repository data source should be include with the imported data. 

Use Case Clarifications

Preparing to Import from Excel

Additional preparation is required to successfully import data from an Excel file.

Defining the Structure 

In order for the Data Repository Tool to recognize data record type hierarchies, at least one worksheet should have a column with a header labeled  <child_sheet_name> dsref*, which establishes the rows in the worksheet as parent nodes. The <child_sheet_name> value should refer to the name of a sheet that contains child rows of data. The child sheet (sheet referenced with <child_sheet_name>) should contain a column with a header labeled ParentIndex. The cells in this column are numerical values that correspond to rows in the parent sheet. See the Example

The dsref* and ParentIndex columns in your worksheets correspond to the Join Column and Parent Join Column fields in the Data Repository Tool configuration (see Configuring Nodes). 

Example

In the following example, the Categories sheet contains a dsref* column that references the Lessons sheet, indicating that the rows of data in Lessons are children of the rows in Categories:  


AB

1

CategoryLessons dsref*
2test automation
3service virtualization
4environment management
5static analysis
6unit testing
Categories


The Lessons sheet contains a ParentIndex column, the values of which correspond to rows in the Categories sheet. The Data Repository Tool ignores the column header row, so the enumeration starts with row 2 in the Categories sheet:

 See  

Parameterizing Arrays of Varying Size

for additional information about dsref* and ParentIndex columns.

Support for Primitive Lists

You can configure the Data Repository Tool to import columns as primitive lists, record lists, and arrays using the Field type setting (see Configuring the Data Repository Tool). The Field type setting becomes available when the following conditions apply:

  • The child worksheet contains only one column. 
  • The name of the child worksheet is the same as the first column in the sheet. 

In the following example, the Field type option will appear for the Videos node when configuring the Data Repository Tool to import the Excel file:

During the tool configuration step, you will be able to choose a field type for the Videos node:

Null and Exclude Values 

The following strings are reserved values that are interpreted as "null" ("nil" for XML traffic): 

  • [parasoft_null]  
  • [null] 

The following strings are reserved values that exclude the value from the generated message, regardless of the message type:

  • [parasoft_exclude]
  • [exclude]

For details on how [parasoft_exclude] works with URL parameter data source correlations, see Matching on Absent/Empty Fields and Parameters.

Adding the Data Repository Tool

  1. Ensure that the Data Repository Server you want to import data into is running.
  2. Create a newprovisioning action file with an empty action suitein a new project or existing project. See Adding Projects, Virtual Assets, and Responder Suites.

  3. Add a new Repository Data Source to the suite. See Creating a Repository Data Source
  4. Open the data source and specify the target data set for importing the data. You can browse existing repositories on the server in the Repository view (see Views in Virtualize ). If the specified repository name or data set does not exist, it will be created at runtime.

  5. Right-click the Action Suite node and choose Add New> Action.and choose Data Repository Tool. 

  6. Click Next. and configure the data and structure initialization options. See Configuring Initialization Options.

  7. Click Finish and configure the Data Repository Tool.

If you initialized the data and the structure based on an Excel file, the workbook will be imported as an Excel data source and the tool will be configured according to the data. Review the tool configuration and modify the settings as necessary before running the tool (see Configuring the Data Repository Tool). 

Configuring Initialization Options

You can configure the following initialization settings when creating a Data Repository Tool. The settings in this screen determine how to initialize the imported data structure.

Initialize data from
Initialize structure from
  • Choose None to manually structure the data.
  • Choose Excel to use the structure from an Excel file to structure the data. Refer to the Preparing to Import from Excel section for information about preparing the data.
  • Choose WSDL to use the structure from a WSDL definition file to structure the data. 
  • Choose Schema to use the structure from a schema file to structure the data.

When specifying WSDLs and schemas, specify the definition file and choose the data type definition from the Type menu.

Join columnIf initializing from an Excel file, specify the name of the column that indicates relationships across Excel sheets in the Join column field. By default, the Join column is the ParentIndex column, but you can also point to another column that contains values for referencing the parent row. See Defining the Structure additional information.

Configuring the Data Repository Tool

Verify that the Target Repository is set to the Repository Data Source that you created (see Adding the Data Repository Tool).

Data Processing Options

In the Tool Settings > Options section, enable a mode for processing data:

  • Append: Adds records to the data an existing set. Existing records will not be altered.
  • OverwriteIf matching records are detected in overwrite mode, they will be replaced.
  • Delete: Removes matching records.

Configuring the Data Structure

If you created the Data Repository Tool without initializing data or a structure, a default New node will appear in the panel.

Click on the node to access it's configuration options (see Configuring Nodes).

If you initialized the structure from Excel during tool creation, the structure will already be applied. You can choose a node from the panel and configure as necessary (see Configuring Nodes).

You can click Add... and Remove in the Import Data panel to manually add nodes to the data tree. You can also right-click on existing nodes to remove the node or add children.

Configuring Nodes

Each node in the data tree represents a part of the source data you are importing. If you chose to initialize data based on one of the options in the initialization screen (Configuring Initialization Options), this section will be configured automatically, but you can modify the following settings as necessary prior to running the tool. 

The available settings depend on the nodes' relationships:

NameSpecifies the name for the node.
Data SourceSpecifies the Excel workbook used to initialize the data (see Configuring Initialization Options). If the None option was enabled, this field will be empty and data will need to be added manually using the data source editor (see Viewing and Modifying the Repository Structure and Contents).
Sheet NameSpecifies a sheet name when importing from Excel.
Join Column

Specifies the name of the column used for indicating relationships across Excel sheets. By default, the ParentIndex column is used (see Defining the Structure). 

If the value in a record’s Join Column matches the value in a Parent Join Column record, then that record becomes a child of the parent record.

This setting is not available for column-level nodes. 

This setting cannot be configured for worksheet-level nodes at the root of the tree.

Parent Join Column

Specifies the column in the parent node used for indicating relationships across Excel sheets. By default, the value is set to <Row Number>, which specifies that the column correlates to the parent row number. 

If the value in a record’s Join Column matches the value in a Parent Join Column record, then that record becomes a child of the parent record.

This setting is not available for column-level nodes. 

This setting cannot be configured for worksheet-level nodes at the root of the tree.

Data ColumnSpecifies name of the column containing the data.
Field Type

Specifies which type the data should be imported as. You can specify one of the following types:

  • Record List: Series of complex records that are hierarchical and have multiple fields/columns.
  • Primitive List (see Support fro Primitive Lists): A list of primitive types.
  • Array: An array of primitive types.

See Viewing and Modifying the Repository Structure and Contents for additional information about types.

Specifying Data Set Keys 

Data set keys allow you to specify key columns that will be used for Virtualize responder correlations. These columns can later be selected in the Data Source Correlations tab.



If you don’t specify these key columns now, you can add them later in the Data Editor.

See Responder Correlation Tab for additional information.

Running the Tool

Select the Data Repository tool that and click Run in the toolbar.Details on the import will be reported in the Console view.

Any problems with the import will be reported in the progress view. For instance, the following message might occur if you are trying to import data into a Repository Server that is not currently running.
