Connect to Google Cloud Storage data in MicroStrategy Developer using the CData ODBC Driver for Google Cloud Storage.
MicroStrategy is an analytics and mobility platform that enables data-driven innovation. When you pair MicroStrategy with the CData ODBC Driver for Google Cloud Storage, you gain database-like access to live Google Cloud Storage data from MicroStrategy, expanding your reporting and analytics capabilities. In this article, we walk through creating a database instance for Google Cloud Storage in MicroStrategy Developer and creating a Warehouse Catalog based on Google Cloud Storage data.
The CData ODBC driver offers unmatched performance for interacting with live Google Cloud Storage data in MicroStrategy due to optimized data processing built into the driver. When you issue complex SQL queries from MicroStrategy to Google Cloud Storage, the driver pushes supported SQL operations, like filters and aggregations, directly to Google Cloud 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 visualize and analyze Google Cloud Storage data using native MicroStrategy data types.
Connect to Google Cloud Storage as an ODBC Data Source
Information for connecting to Google Cloud Storage follows, along with different instructions for configuring a DSN in Windows and Linux environments (the ODBC Driver for Google Cloud Storage must be installed on the machine hosting the connected MicroStrategy Intelligence Server).
Authenticate with a User Account
You can connect without setting any connection properties for your user credentials. After setting InitiateOAuth to GETANDREFRESH, you are ready to connect.
When you connect, the Google Cloud Storage OAuth endpoint opens in your default browser. Log in and grant permissions, then the OAuth process completes
Authenticate with a Service Account
Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes.
You need to create an OAuth application in this flow. See the Help documentation for more information. After setting the following connection properties, you are ready to connect:
- InitiateOAuth: Set this to GETANDREFRESH.
- OAuthJWTCertType: Set this to "PFXFILE".
- OAuthJWTCert: Set this to the path to the .p12 file you generated.
- OAuthJWTCertPassword: Set this to the password of the .p12 file.
- OAuthJWTCertSubject: Set this to "*" to pick the first certificate in the certificate store.
- OAuthJWTIssuer: In the service accounts section, click Manage Service Accounts and set this field to the email address displayed in the service account Id field.
- OAuthJWTSubject: Set this to your enterprise Id if your subject type is set to "enterprise" or your app user Id if your subject type is set to "user".
- ProjectId: Set this to the Id of the project you want to connect to.
The OAuth flow for a service account then completes.
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 Google Cloud 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

Create a Google Cloud Storage Database Instance in MicroStrategy Developer
You can connect to Google Cloud Storage in MicroStrategy Developer by adding a database instance based on the CData ODBC Driver for Google Cloud Storage.*
- Open MicroStrategy Developer and select a Project Source.
- Navigate to Administration -> Configuration Managers -> Database Instances and right-click to add a new instance.
- Name the instance, select Generic DBMS as the database connection type, and create a new database connection.
- In the database connection wizard, name the connection and create a new Database Login name, using filler values for the user and password.
- Select the DSN that you configured earlier as the ODBC data source (i.e., CData GoogleCloudStorage Sys).
- Select the newly created database connection.
- In the Project Source, right-click the project and open the Project configuration.
- Navigate to Database Instances and select the newly created database instance.
- Close MicroStrategy Developer and restart the connected MicroStrategy Intelligence Server to complete the database instance creation.
With the database instance configured, you will now be able to connect to Google Cloud Storage data from the Warehouse Catalog and Data Import.
Connect to Google Cloud Storage Data from the Warehouse Catalog
Once you have created a database instance based on the ODBC Driver for Google Cloud Storage, you can connect to data from the Warehouse Catalog.
- Select your project and click Schema -> Warehouse Catalog.
- In the Read Settings for the Catalog, click Settings and set the queries to retrieve the schema:
- To retrieve the list of tables, use the following query:
SELECT CatalogName NAME_SPACE, TableName TAB_NAME FROM SYS_TABLES
- To retrieve the list of columns for selected tables, use the following query:
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
- To retrieve the list of tables, use the following query:
- Select tables to be used in the project.

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