How to add a Data Hub to existing ALM structure
Our current workspace/structure as follows:
ALM: DEV --> TEST, DEV --> PROD
We are considering implementing a Data Hub to hold transactional data & be the single source of truth. I know it is best practice to first create the Data Hub and then the other spoke models; however, this is a 3 year old client model. I am wondering what is best practice on how to implement a data hub in this case? How would I go about ALM? How would the structure/architecture look like and what are some things to take into consideration.
If there is a how to article with steps and instructions, please link. Thank you!
