It was a call from one of the business sub-teams of our project. The leader wanted to discuss something about the data and data model.  The call was just like a call-order for the data model. I was so excited, you know.

Nobody, except our data model sub-team, knew what the data model was and what we did it fou, when I joint the sub-team two weeks ago. It was very disappointed really. So, the first thing I faced is how we sell the data model to the business team. Through a interview with the leader , who is the leader of a sub-team, he began to understood something about the data model, and realized that we could do something valuable for them.

It is a good start.
