how it works

Create a dGraph

After you login to the site, go to your list of dGraphs. You can find this in your user toolbox under "dgraph list". Create a dGraph and by clicking the "Add New dGraph" link at the bottom of the page.

Now create a dGraph by filling out the required fields. To define the Auto dGraph used as the example thoughout this site use the name "Auto" for object anme. Press the "Save and Setup" button to create the dGraph and begin defining fields. You can specify individual fields or use an upload file. Save the following text to a file and upload it as your field definition file.

Implement Repository

After you have saved your new graph, go back to the dGraph Maintenance screen and click the "Implement" link. This will bring you to a page to confirm that you wish to actually create the graph in production. Simply click the "Implement" on this page to create the a working repository. In your web.config file or app.config file you will need to add this secion to the servicemodel section.

Add Data

Now that you have a working repository you can add data to it. This is done programatically by connecting to your custom web service and uploading data. Open a VS.NET project and add a service reference. Use the Access URL for the repository. This can be found on the dGraph list screen. The URL will look something like this "http://www.celeriq.com/services/X415239ebe7e44f9dbc6e56dc855c81b2.svc". Choose a name for the service. I have choosen "RepositoryService" for this example.

Simple declare the service and declare the custom object. In this example, we named our object "Auto" so we have a strongly-typed object called "AutoItem". Decalre an object of this type, set its properties and save it. That is all that needs to be done. The data is in the repository now. You can also add an array of these object by calling the "AddDataList" method instead of the "AddData" method. When you are done adding data, call the "Summarize" method to signal that you have completed the import operation.

Query Data

Now you can query the data using the web service.
