Integrating External Data Using Bold Data Hub

In this article, we will demonstrate how to import tables from a CSV file, join with external customer data through transformations, and move the cleaned data into the destination database using Bold Data Hub. Follow the step-by-step process below.

Sample Data Source:

Tickets
Customers

Creating Pipeline

Learn about [Pipeline Creation] (https://help.boldbi.com/working-with-data-sources/working-with-bold-data-hub/working-with-pipelines/)

Applying Transformation

• Go to the Transform tab and click Add Table.

• Enter the table name to create a transform table for customer satisfaction summary.

Note: The data will initially be transferred to the DuckDB database within the designated {pipeline_name} schema before undergoing transformation for integration into the target databases. As an illustration, in the case of a pipeline named “customer_service_data”, the data will be relocated to the customer_service_data table schema.

Joining with External Customer Data

Overview

Integrating Customer Support Center (CSC) data with Customer Relationship Management (CRM) data enriches support tickets with customer-related attributes. This helps in deeper analysis of customer demographics, spending behavior, and loyalty status.

Approach

We use a LEFT JOIN to merge ticket data with customer data, ensuring all tickets are retained even if some customers have missing CRM details.
