How to Create Power BI Visual Reports with Real-Time EnterpriseDB Data

CData Power BI Connectors provide self-service integration with Microsoft Power BI. The CData Power BI Connector for EnterpriseDB links your Power BI reports to real-time EnterpriseDB data. You can monitor EnterpriseDB data through dashboards and ensure that your analysis reflects EnterpriseDB data in real time by scheduling refreshes or refreshing on demand. This article details how to use the Power BI Connector to create real-time visualizations of EnterpriseDB data in Microsoft Power BI Desktop.

Collaborative Query Processing

The CData Power BI Connectors offer unmatched performance for interacting with live EnterpriseDB data in Power BI due to optimized data processing built into the connector. When you issue complex SQL queries from Power BI to EnterpriseDB, the connector pushes supported SQL operations, like filters and aggregations, directly to EnterpriseDB and utilizes the embedded SQL Engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can visualize and analyze EnterpriseDB data using native Power BI data types.

Connect to EnterpriseDB as a Power BI Data Source

Installing the Power BI Connector creates a DSN (data source name) called CData Power BI EnterpriseDB. This the name of the DSN that Power BI uses to request a connection to the data source. Configure the DSN by filling in the required connection properties.

You can use the Microsoft ODBC Data Source Administrator to create and configure the DSN: From the Start menu, enter "ODBC Data Sources" and select the CData PowerBI REST DSN. Ensure that you run the version of the ODBC Administrator that corresponds to the bitness of your Power BI Desktop installation (32-bit or 64-bit). You can also use run the ConfigureODBC.exe tool located in the installation folder for the connector.

The following connection properties are required in order to connect to data.

• Server: The host name or IP of the server hosting the EnterpriseDB database.
• Port: The port of the server hosting the EnterpriseDB database.

You can also optionally set the following:

• Database: The default database to connect to when connecting to the EnterpriseDB Server. If this is not set, the user's default database will be used.

Connect Using Standard Authentication

To authenticate using standard authentication, set the following:

• User: The user which will be used to authenticate with the EnterpriseDB server.
• Password: The password which will be used to authenticate with the EnterpriseDB server.

Connect Using SSL Authentication

You can leverage SSL authentication to connect to EnterpriseDB data via a secure session. Configure the following connection properties to connect to data:

• SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
• SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
• SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
• SSLClientCertType: The certificate type of the client store.
• SSLServerCert: The certificate to be accepted from the server.

How to Query EnterpriseDB Tables

Follow the steps below to build a query to pull EnterpriseDB data into the report:

1. Open Power BI Desktop and click Get Data -> Other -> CData EnterpriseDB.
2. Select CData PowerBI EnterpriseDB in the Data Source Name menu and select a data connectivity mode:
   Select Import if you want to import a copy of the data into your project. You can refresh this data on demand.
   Select DirectQuery if you want to work with the remote data.
3. Select tables in the Navigator dialog.

4. In the Query Editor, you can customize your dataset by filtering, sorting, and summarizing EnterpriseDB columns. Click Edit to open the query editor. Right-click a row to filter the rows. Right-click a column header to perform actions like the following:

   • Change column data types
   • Remove a column
   • Group by columns

   Power BI detects each column's data type from the EnterpriseDB metadata retrieved by the connector.

   Power BI records your modifications to the query in the Applied Steps section, adjusting the underlying data retrieval query that is executed to the remote EnterpriseDB data. When you click Close and Apply, Power BI executes the data retrieval query.

   Otherwise, click Load to pull the data into Power BI.

How to Create Data Visualizations in Power BI

After pulling the data into Power BI, you can create data visualizations in the Report view by dragging fields from the Fields pane onto the canvas. Follow the steps below to create a pie chart:

1. Select the pie chart icon in the Visualizations pane.
2. Select a dimension in the Fields pane: for example, ShipName.
3. Select a measure in the Fields pane: for example, ShipCity.

You can change sort options by clicking the ellipsis (...) button for the chart. Options to select the sort column and change the sort order are displayed.

You can use both highlighting and filtering to focus on data. Filtering removes unfocused data from visualizations; highlighting dims unfocused data. You can highlight fields by clicking them:

You can apply filters at the page level, at the report level, or to a single visualization by dragging fields onto the Filters pane. To filter on the field's value, select one of the values that are displayed in the Filters pane.

Click Refresh to synchronize your report with any changes to the data.

At this point, you will have a Power BI report built on top of live EnterpriseDB data. Learn more about the CData Power BI Connectors for EnterpriseDB and download a free trial from the CData Power BI Connector for EnterpriseDB page. Let our Support Team know if you have any questions.
