Connect to Google Data Catalog Data in RunMyProcess through Connect Server

Akorbi Digital RunMyProcess makes it easy to create applications for complex business processes, such as budget application and contract management. CData Connect creates a virtual database for Google Data Catalog and can be used to generate an OData API (natively consumable in RunMyProcess) for Google Data Catalog. By pairing RunMyProcess with the CData Connect Server, you get direct connectivity to all your SaaS and cloud-based Big Data and NoSQL sources - no need to migrate your data or write your own integrations. Simply connect to Connect Server from RunMyProcess as you would any other REST service and get instant, live access to your Google Data Catalog data.

In this article, we walk through connecting to Google Data Catalog from CData Connect and accessing Google Data Catalog data through an OData feed in RunMyProcess.

Configuring Connect Server

To work with live Google Data Catalog data in RunMyProcess, we need to connect to Google Data Catalog from Connect Server, provide user access to the new virtual database, and create OData endpoints for the Google Data Catalog data.

Add a Connect Server User

Create a User to connect to Google Data Catalog from RunMyProcess through Connect Server.

1. Click Users -> Add
2. Configure a User
3. Click Save Changes and make note of the Authtoken for the new user

Connect to Google Data Catalog from Connect Server

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Open Connect Server and click Connections
2. Select "Google Data Catalog" from Available Data Sources
3. Enter the necessary authentication properties to connect to Google Data Catalog

   Google Data Catalog uses the OAuth authentication standard. Authorize access to Google APIs on behalf on individual users or on behalf of users in a domain.

   Before connecting, specify the following to identify the organization and project you would like to connect to:

   • OrganizationId: The ID associated with the Google Cloud Platform organization resource you would like to connect to. Find this by navigating to the cloud console.

     Click the project selection drop-down, and select your organization from the list. Then, click More -> Settings. The organization ID is displayed on this page.

   • ProjectId: The ID associated with the Google Cloud Platform project resource you would like to connect to.

     Find this by navigating to the cloud console dashboard and selecting your project from the Select from drop-down. The project ID will be present in the Project info card.

   When you connect, the OAuth endpoint opens in your default browser. Log in and grant permissions to the application to completes the OAuth process. For more information, refer to the OAuth section in the Help documentation.

4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for RunMyProcess).

Add Google Data Catalog OData Endpoints in Connect Server

After connecting to Google Data Catalog, create OData Endpoints for the desired table(s).

1. Click OData -> Tables -> Add Tables
2. Select the Google Data Catalog database
3. Select the table(s) you wish to work with and click Next
4. (Optional) Edit the resource to select specific fields and more
5. Save the settings

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple domains from an application, such as Ajax, you might violate the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.

• Enable cross-origin resource sharing (CORS): ON
• Allow all domains without '*': ON
• Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
• Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Sample URLs for OData Feeds

Once you have configured a connection to Google Data Catalog, created a user, and created OData endpoints in Connect Server, you can access OData feeds for Google Data Catalog data. Below, you will see the URLs to access tables and the list of tables. For information on accessing the tables, you can navigate to the API page for Connect Server (click the API link on the top right of Connect Server Web page). For the URLs, you will need the URL of Connect Server, likely in the form: CONNECT_SERVER_URL/. Since we are working with Angular, we will append the @json parameter to the end of URLs that do not return JSON data by default.

As with standard OData feeds, if you wish to limit the fields returned, you can add a $select parameter to the query, along with other standard OData URL parameters, such as $filter, $orderby, $skip, and $top. See the help documentation for more information on supported OData queries.

Retrieve Google Data Catalog Data from RunMyProcess DigitalSuite Studio

With the connection to Google Data Catalog and OData endpoints created, we are ready to add Google Data Catalog data to RunMyProcess for retrieval.

Create a Provider

1. Log into RunMyProcess and open DigitalSuite Studio.
2. Click Resources to bring up the Resources page, then select then the CONNECTORS tab. 　　
3. Click the + (New Provider) button to create a new provider, choose the project to use, then click Confirm.
4. In the provider settings page, configure the following properties.
   • URL：Set the OData endpoint in the CData Connect Endpoints page.e.g. CONNECT_SERVER_URL/api.rsc/
   • Authentication Schema：Select Login/Password.
   • Login：Specify the CData Connect User name configured above.
   • Password：Specify the Authtoken of the user.
5. Fill in the same properties in the ACCEPTANCE and TEST tabs. Note: You can copy the configured settings by clicking 'Copy this configuration button,' then pasting the content in the new tab by clicking 'Paste previously copied configuration.'
6. Click Save to save the properties.

Retrieve Google Data Catalog Data by Creating a Connector

1. In the CONNECTORS tab, click the button with three dots to create the provider, then select Add connector from the menu.
2. In the following page, set Connector URL to the OData endpoint configured in Connect Server.e.g. odataendpoint/
3. Click Save then Launch to test the connector execution. Click Launch test to execute. The process is successful if you get the JSON response of your configured table information.
