My experience with Talend Open Studio for MDM is supporting an existing customer.

It is used for master data management and is often utilized by industries, companies, or organizations that do a lot of acquisitions and mergers. In cases where there is a lot of different customer information from different areas, they tend to use MDM. Also, in certain regions where a customer is registering in multiple domains, they use this tool to create the master record.

I use the solution for various reasons in projects. It helps with data warehousing, file cleansing, and various business transformations.
