Use the CData ODBC Driver for IBM Cloud Object Storage in SAS for Real-Time Reporting and Analytics

SAS is a software suite developed for advanced analytics, multivariate analysis, business intelligence, data management, and predictive analytics. When you pair SAS with the CData ODBC Driver for IBM Cloud Object Storage, you gain database-like access to live IBM Cloud Object Storage data from SAS, expanding your reporting and analytics capabilities. This article explains how to create a library for IBM Cloud Object Storage in SAS and create a simple report based on real-time IBM Cloud Object Storage data.

The CData ODBC Driver offers unmatched performance for interacting with live IBM Cloud Object Storage data in SAS due to optimized data processing built into the driver. When you issue complex SQL queries from SAS to IBM Cloud Object Storage, the driver pushes supported SQL operations, like filters and aggregations, directly to IBM Cloud Object Storage 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 easily visualize and analyze IBM Cloud Object Storage data in SAS.

Connect to IBM Cloud Object Storage as an ODBC Data Source

Information for connecting to IBM Cloud Object Storage follows, along with different instructions for configuring a DSN in Windows and Linux environments (the ODBC Driver for IBM Cloud Object Storage must be installed on the machine hosting the SAS System).

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

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, 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.

Windows

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Linux

If you are installing the CData ODBC Driver for IBM Cloud Object Storage in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData IBMCloudObjectStorage Sys]
Driver = CData ODBC Driver for IBM Cloud Object Storage
Description = My Description
ApiKey = myApiKey
CloudObjectStorageCRN = MyInstanceCRN
Region = myRegion
OAuthClientId = MyOAuthClientId
OAuthClientSecret = myOAuthClientSecret

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Create a IBM Cloud Object Storage Library in SAS

Connect to IBM Cloud Object Storage in SAS by adding a library based on the CData ODBC Driver for IBM Cloud Object Storage.

1. Open SAS and expand Libraries in the Explorer pane.
2. In the Active Libraries window, right-click and select New.
3. Name your library (odbclib), select ODBC as the Engine, and click to Enable at startup (if you want the library to persist between sessions).
4. Set Data Source to the DSN you previously configured and click OK. 👁 Creating a library for IBM Cloud Object Storage in SAS.
   

Create a View from a IBM Cloud Object Storage Query

SAS natively supports querying data either using a low-code, point-and-click Query tool or programmatically with PROC SQL and a custom SQL query. When you create a View in SAS, the defining query is executed each time the view is queried. This means that you always query live IBM Cloud Object Storage data for reports, charts, and analytics.

Using the Query Tool

1. In SAS, click Tools -> Query
2. Select the table sources and the table(s) you wish to pull data from. Then, click OK. 👁 Selecting table(s) to visualize.
   
3. Select columns and right-click to add filtering, ordering, grouping, etc. 👁 Selecting columns(s) to visualize and configuring the query.
   
4. Create a local view to contain the query results by right-clicking the SQL Query Tool window, selecting Show Query, and clicking Create View. Name the View and click OK. 👁 Create a local view to work with IBM Cloud Object Storage data.
   

Using PROC SQL

1. In SAS, navigate to the Editor window.
2. Use PROC SQL to query the data and create a local view.
   NOTE: This procedure creates a view in the Work library. You can optionally specify a library in the create view statement.

   proc sql;
    create view objects_view as
    select 
    key, 
    etag 
    from 
    odbclib.objects 
    where 
    Bucket = 'someBucket';
   quit;
   

3. Click Run -> Submit to execute the query and create a local view.

Report On or Visualize IBM Cloud Object Storage Data in SAS

With a local view created, you can report, visualize, or otherwise analyze IBM Cloud Object Storage data using the powerful SAS features. Print a simple report using PROC PRINT and create a basic graph based on the data using PROC GCHART.

Print an HTML Report

1. In SAS, navigate to the Editor window.
2. Use PROC PRINT to print an HTML report for the IBM Cloud Object Storage Objects data.

   proc print data=objects;
    title "IBM Cloud Object Storage Objects Data";
   run;

Print a Chart

1. In SAS, navigate to the Editor window.
2. Use PROC GCHART to create a chart for the Objects data.

   proc gchart data=objects;
    pie key / sumvar=etag
    value=arrow
    percent=arrow
    noheading
    percent=inside plabel=(height=12pt)
    slice=inside value=none
    name='ObjectsChart';
   run;
