Using the Microsoft ODBC Data Source Administrator

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the DSN is created during the installation process.

Complete the following steps to edit the DSN configuration:

1. Select Start > Search, and enter ODBC Data Sources in the Search box.
2. Choose the version of the ODBC Administrator that corresponds to the bitness of your application (32-bit or 64-bit).
3. Click the System DSN tab.
4. Select the system data source and click Configure.
5. Edit the information on the Connection tab and click OK.

Note: For .NET Framework 4.0, the driver distributes Microsoft Visual C++ 2015-2022 Redistributable. For .NET Framework 3.5, the driver distributes Microsoft Visual C++ 2008 Redistributable.

Ensuring Registry Access

The driver stores connection information in the Windows registry. To ensure that the driver can write to the registry, perform either of the following actions:

1. Run the calling application as an administrator.
2. Connect via a User DSN instead of a System DSN.

Modeling XML/JSON/CSV Data

The DataModel property controls how your data is represented into tables.

• Document (default): Model a top-level, document view of your REST data. The driver returns nested object arrays as aggregated XML/JSON/CSV objects.
• FlattenedDocuments: Implicitly join nested array objects and parent objects into a single table.
• Relational: View nested object arrays as individual, related tables containing a primary key and a foreign key that links to the parent document.

Set Format to XML, JSON, or CSV in accordance with the data structuring standard used by the REST source you want to connect to. and set DataModel to more closely match the data representation to the structure of your data.

• See Fine-Tuning Data Access for more advanced connection settings: fine-tune the default data modeling settings, connect through a firewall, or troubleshoot connections.
