Analyze DB2 Data in SAP Analytics Cloud

SAP Analytics Cloud is a cloud-based business intelligence platform. The CData Connect Server creates a virtual database for DB2 and can be used to generate an OData API (natively consumable in Analytics Cloud) for DB2. By pairing SAP Analytics Cloud with the CData Connect Server, you get direct connectivity to all of your SaaS and cloud-based Big Data and NoSQL sources — no need to migrate your data or write your integrations. Simply connect to Connect Server as you would any other OData service and get instant, consolidated access to all of your data.

In this article, we walk through connecting to DB2 in Connect Server and connecting to Connect Server from Analytics Cloud to create a model and build a simple dashboard.

Configure Connect Server to Connect to DB2

To connect to DB2 data from SAP Analytics Cloud, you need to configure DB2 access from your Connect Server instance. This means creating a user, connecting to DB2, adding OData endpoints, and (optionally) configuring CORS.

Add a Connect Server User

Create a User to connect to DB2 from Analytics Cloud 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 DB2 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 "DB2" from Available Data Sources
3. Enter the necessary authentication properties to connect to DB2.

   Set the following properties to connect to DB2:

   • Server: Set this to the name of the server running DB2.
   • Port: Set this to the port the DB2 server is listening on.
   • Database: Set this to the name of the DB2 database.
   • User: Set this to the username of a user allowed to access the database.
   • Password: Set this to the password of a user allowed to access the database.

   You will also need to install the corresponding DB2 driver:

   • Windows: Install the IBM Data Server Provider for .NET.

     On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.

   • Java: Install the IBM Data Server Driver for JDBC.

     In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.

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 Reveal)

Add DB2 OData Endpoints in Connect Server

After connecting to DB2, create OData Endpoint for the desired table(s).

1. Click OData -> Tables -> Add Tables
2. Select the DB2 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 different domains from an application such as Ajax, there is a possibility of violating 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.

Create a Model of DB2 Data in SAP Analytics Cloud

With the connection to DB2 configured and the OData endpoint(s) created, we can create a Model for DB2 data in SAP Analytics Cloud.

1. Log into your Analytics Cloud instance and click Create -> Model from the menu.
2. Choose "Get data from a datasource" and select "OData Services"
3. Choose an existing connection to your Connect Server OData or Create a new one:
   • Set "Connection Name"
   • Set "Data Service URL" to the Base URL for your OData API (typically: CONNECT_SERVER_URL/api.rsc)
   • Set "Authentication Type" to Basic Authentication
   • Set "User Name" to the Connect Server user you configured earlier
   • Set "Password" to the Authtoken for the above user
4. Choose "Create a new query" and click Next
5. Name the Query, select an OData endpoint (like db2db_Orders) and click Next
6. Drag the columns you wish to work with into the Selected Data workspace and click Create
7. At this point, a Draft Data source is created; click the draft to finalize the model
8. Perform any transformations, including creating calculated dimensions, location dimensions, and combining data sources, then click Create Model
9. Name your model and click OK

Build a Dashboard in SAP Analytics Cloud

With the model created, you are ready to create a dashboard in SAP Analytics Cloud based on DB2 data.

1. From the menu, click Create -> Story
2. Click an SAP Analytics Template (this article uses the "Dashboard" template)
3. Choose a layout and click Apply
4. From the More menu, select a visualization to insert (Chart)
5. Select a model to visualize
6. Select a structure and the required Measures and Dimensions
7. Save the story
