Connecting to OData


1. Overview

OData (or Open Data Protocol) is a REST-based data access protocol which was initially defined by Microsoft.

This article shows you how to connect to OData services such as Microsoft Azure Marketplace.

For a list of available services, see OData - Live Services.

2. Connect to the OData Sample Service

Follow these steps to connect to a sample test service provided by

Go to the main menu in Dundas BI and create a new data connector.

Click Submit to create the data connector and connect to the service.

To check the results, create a new dashboard from the main menu.

3. Connect to SharePoint

You can also connect to data on your SharePoint server using the OData protocol.

For example, set the Address to http://spserver/_vti_bin/listdata.svc/ and the Authentication method to Specified Windows credentials.

4. Advanced properties

By default, the OData connector will auto-detect the OData version, but you can use the OData Service Version option to force a specific version (e.g., between V1 and V4).

The Records Per Page option specifies the number of records or rows to fetch at a time. By default, it is set to 100 but you can increase this in order to load data faster.

5. Using query options

Queries sent to the data source can include various options that you can set, including $filter$expand$top$skip, $select$orderby, and (when using OData version 4) $search.

These can be set when selecting a table in a data cube, by configuring its Tabular Select transform and clicking Parameters.

Click to edit one of the predefined parameters, and set the Value using the syntax used by OData query options following the equal (=) sign.

For example, the $filter parameter could be set to IataCode eq 'LAX'.

You will also find a Programmatic Structures folder located directly under the data connector, listing the results of the $count query option for each table, which you can drag onto a data cube or metric set.
