Use the CData ODBC Driver for Nuclia in MicroStrategy

MicroStrategy is an analytics and mobility platform that enables data-driven innovation. When you pair MicroStrategy with the CData ODBC Driver for Nuclia, you gain database-like access to live Nuclia data from MicroStrategy, expanding your reporting and analytics capabilities. In this article, we walk through creating a database instance for Nuclia in MicroStrategy Developer and creating a Warehouse Catalog based on Nuclia data.

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

Connect to Nuclia as an ODBC Data Source

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

Using API Key Authentication

Nuclia uses API key authentication for accessing Knowledge Box data. To obtain an API key:

1. Log in to the Nuclia Cloud Dashboard at https://nuclia.cloud
2. Navigate to your Knowledge Box settings
3. Go to the Service Accounts section
4. Create a new service account or copy an existing API key

After obtaining your API key, set the following connection properties:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your Nuclia service account API key.
• KbId: Set this to your Knowledge Box UUID.
• Zone: Set this to your Nuclia deployment zone (e.g., aws-us-east-2-1).

Example Connection String

Profile=C:\profiles\Nuclia.apip;AuthScheme=APIKey;APIKey=your_service_account_key;KbId=your_kb_uuid;Zone=aws-us-east-2-1;

Connecting to Nuclia

Once the authentication is configured, you can connect to Nuclia and query data from any of the available tables such as Resources, KnowledgeBox, LabelSets, and ProcessingStatus.

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 Nuclia 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 Nuclia
Description = My Description
Profile = C:\profiles\Nuclia.apip
AuthScheme = APIKey
APIKey = your_service_account_key
KbId = your_kb_uuid
Zone = aws-us-east-2-1

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

Create a Nuclia Database Instance in MicroStrategy Developer

You can connect to Nuclia in MicroStrategy Developer by adding a database instance based on the CData ODBC Driver for Nuclia.^*

1. Open MicroStrategy Developer and select a Project Source.
2. Navigate to Administration -> Configuration Managers -> Database Instances and right-click to add a new instance.
3. Name the instance, select Generic DBMS as the database connection type, and create a new database connection.
4. In the database connection wizard, name the connection and create a new Database Login name, using filler values for the user and password. 👁 Create a new database login.
   
5. Select the DSN that you configured earlier as the ODBC data source (i.e., CData API Sys). 👁 Choosing the DSN for the database connection.
   
6. Select the newly created database connection.
👁 The configured database instance.

7. In the Project Source, right-click the project and open the Project configuration.
8. Navigate to Database Instances and select the newly created database instance. 👁 Adding the new database instance to the project.
   
9. 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 Nuclia data from the Warehouse Catalog and Data Import.

Connect to Nuclia Data from the Warehouse Catalog

Once you have created a database instance based on the ODBC Driver for Nuclia, you can connect to data from the Warehouse Catalog.

1. Select your project and click Schema -> Warehouse Catalog. 👁 Creating the Warehouse Catalog
   
2. 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
      

   👁 Custom metadata queries.
   
3. Select tables to be used in the project. 👁 Selecting tables to be used in the project.
