DBxtra で IBM Cloud Object Storage Data に連携するダッシュボードを作成

DBxtra でIBM Cloud Object Storage に連携して、ダイナミックダッシュボードでデータを分析。

CData ODBC Driver for IBM Cloud Object Storage は、IBM Cloud Object Storage データを標準SQL で使えるようにし、BI、帳票、ETL ツールからの連携を実現します。本記事では、DBxtra からIBM Cloud Object Storage データにGeneric ODBC として接続し、レポートやダッシュボードを作成します。

IBM Cloud Object Storage Data への連携

  1. If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can configure the DSN using the built-in Microsoft ODBC Data Source Administrator. This is also the last step of the driver installation. See the "Getting Started" chapter in the Help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

    Register a New Instance of Cloud Object Storage

    If you do not already have Cloud Object Storage in your IBM Cloud account, follow the procedure below to install an instance of SQL Query in your account:

    1. Log in to your IBM Cloud account.
    2. Navigate to the page, choose a name for your instance and click Create. You will be redirected to the instance of Cloud Object Storage you just created.

    Connecting using OAuth Authentication

    There are certain connection properties you need to set before you can connect. You can obtain these as follows:

    API Key

    To connect with IBM Cloud Object Storage, you need an API Key. You can obtain this as follows:

    1. Log in to your IBM Cloud account.
    2. Navigate to the Platform API Keys page.
    3. On the middle-right corner click "Create an IBM Cloud API Key" to create a new API Key.
    4. In the pop-up window, specify the API Key name and click "Create". Note the API Key as you can never access it again from the dashboard.

    Cloud Object Storage CRN

    If you have multiple accounts, you will need to specify the CloudObjectStorageCRN explicitly. To find the appropriate value, you can:

    • Query the Services view. This will list your IBM Cloud Object Storage instances along with the CRN for each.
    • Locate the CRN directly in IBM Cloud. To do so, navigate to your IBM Cloud Dashboard. In the Resource List, Under Storage, select your Cloud Object Storage resource to get its CRN.

    Connecting to Data

    You can now set the following to connect to data:

    • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
    • ApiKey: Set this to your API key which was noted during setup.
    • CloudObjectStorageCRN (Optional): Set this to the cloud object storage CRN you want to work with. While the connector attempts to retrieve this automatically, specifying this explicitly is recommended if you have more than Cloud Object Storage account.

    When you connect, the connector completes the OAuth process.

    1. Extracts the access token and authenticates requests.
    2. Saves OAuth values in OAuthSettingsLocation to be persisted across connections.

    When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

  2. Open the DBxtra application and in the New menu click Project and name the Project.
  3. Select ODBC Connection as the Data Connection Type.
  4. Click the browse option () for the Data Source.
  5. In the Data Link Properties window, select Microsoft OLE DB Provider for ODBC Drivers on the Provider tab.
  6. On the Connection tab, select the Data Source Name and the initial catalog to use (CData).
  7. Name the Connection and select the appropriate User Groups.
  8. Double-click the Connection from within the Project to connect to the data.

IBM Cloud Object Storage Data に連携するダッシュボードの作成

You are now ready to create a dashboard with IBM Cloud Object Storage data.

  1. Right-click Report Objects under the Project and select New Report Object.
  2. In the new Report Object, click the link to create the Query.
  3. In the Select Data Connection window, select the newly created data connection.
  4. On the Query tab, expand the connection objects and select the Tables, Views, and specific columns you wish to include in your dashboard. You can specify search requirements and even create complex queries which include JOINs and aggregations.
  5. On the Dashboard tab, select the visualizations and features for your dashboard. Assign the data values from the query to the appropriate fields for the Dashboards items (Values, Series, etc.)

With a new Dashboard created, you are ready to begin analysis of IBM Cloud Object Storage data. Thanks to the ODBC Driver for IBM Cloud Object Storage, you can refresh the Dashboard and immediately see any changes made at the source. In the same way, you can create and view Reports with live, up-to-date IBM Cloud Object Storage data.
