We're using this solution for some pharmaceutical companies. 

The solution is deployed on-prem. Right now, we're using version 11.6

When users update their information on one product, the data is sent to a database. My approach was to maintain a master data record, ensuring that each platform loads the latest updated record. Instead of having three separate records, the system keeps one master data record, storing the historical records for reference.

It is not difficult for a person to learn to work with IBM InfoSphere MDM. You need the right mentor, people, and support. I received support mainly from IBM account managers and technical sources assigned to the organization. This support made it easier for me to solve problems.

Our use cases were working with clients who had MDM. All of them had MDM installed to begin with.
