Use the CData ODBC Driver for Canny in MicroStrategy Web

MicroStrategy is an analytics and mobility platform that enables data-driven innovation. When you pair MicroStrategy with the CData ODBC Driver for Canny, you gain database-like access to live Canny data from MicroStrategy, expanding your reporting and analytics capabilities. In this article, we walk through adding Canny as external data in MicroStrategy Web and creating a simple visualization of Canny data.

The CData ODBC driver offers unmatched performance for interacting with live Canny data in MicroStrategy due to optimized data processing built into the driver. When you issue complex SQL queries from MicroStrategy to Canny, the driver pushes supported SQL operations, like filters and aggregations, directly to Canny 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 Canny data using native MicroStrategy data types.

Connect to Canny as an ODBC Data Source

Information for connecting to Canny follows, along with different instructions for configuring a DSN in Windows and Linux environments (the ODBC Driver for Canny must be installed on the machine hosting the connected MicroStrategy Intelligence Server).

Start by setting the Profile connection property to the location of the Canny Profile on disk (e.g. C:\profiles\Canny.apip). Next, set the ProfileSettings connection property to the connection string for Canny (see below).

Canny API Profile Settings

Canny uses a secret API key to control access to the API. The API key is sent as a JSON body parameter named 'apiKey' in every HTTP POST request to the Canny API endpoints.

To authenticate with the Canny API, you need your company-level secret API key. You can find this key in your Canny account under Settings > API.

After setting the following connection properties, you are ready to connect:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your Canny company-level secret API key from the Settings > API page in your Canny dashboard.

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 Canny 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 API Sys]
Driver = CData ODBC Driver for Canny
Description = My Description
Profile = C:\profiles\Canny.apip
ProfileSettings = 'APIKey = your-canny-api-key'

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

Connect to and Visualize Canny Data using MicroStrategy Web

Once you have created a database instance in MicroStrategy Developer and connected it to a project, you can perform a data import of Canny data from MicroStrategy Web. Alternatively, you can create a new data source based on the ODBC Driver.^*

1. Open MicroStrategy Web and select your project.
2. Click Add External Data, select Databases, and choose Select a Table as the Import Option.
3. In the Import from Tables wizard, click to add a new data source.
   • Select DSN Data Sources
   • Set the DSN property to the previously configured DSN (CData API Sys)
   • Set the Version property to Generic DBMS
   • Set the User and Password properties (or use filler values)
   • Set the Data Source Name
   
4. After creating the data source, click to edit the catalog options and set the following queries and click OK.
   • SQL statement to retrieve tables available in the data source

     SELECT
       CatalogName NAME_SPACE,
       TableName TAB_NAME
     FROM
       SYS_TABLES
         

   • SQL statement to retrieve columns for the selected tables

     SELECT DISTINCT 
       CatalogName NAME_SPACE, 
       TableName TAB_NAME, 
       ColumnName COL_NAME, 
       DataTypeName DATA_TYPE, 
       Length DATA_LEN, 
       NumericPrecision DATA_PREC, 
       NumericScale DATA_SCALE 
     FROM 
       SYS_TABLECOLUMNS 
     WHERE 
       TableName IN (#TABLE_LIST#) 
     ORDER BY
       1,2,3
         

5. Drag a table into the pane. Note: Since we create a live connection, we can import whole tables and utilize the filtering and aggregation features native to the MicroStrategy products.
6. Click Finish, choose to the option to connect live, save the query, and choose the option to create a new dossier.
7. Choose a visualization, choose fields to display, and apply any filters to create a new visualization of Canny data. Data types are discovered automatically through dynamic metadata discovery. Where possible, the complex queries generated by the filters and aggregations will be pushed down to Canny, while any unsupported operations (which can include SQL functions and JOIN operations) will be managed client-side by the CData SQL engine embedded in the driver.
8. Once you have finished configuring the dossier, click File -> Save.

Using the CData ODBC Driver for Canny in MicroStrategy Web, you can easily create robust visualizations and reports on Canny data. Read our other articles on connecting to Canny in MicroStrategy and connecting to Canny in MicroStrategy Desktop for more examples.

Note: connecting using a ODBC driver requires a 3- or 4-tier architecture.
