The consistency we talk about here is mainly about consistency in the naming of the entities and attributes of our data models, as well as consistency in the language that we use to discuss and communicate the requirements at the application level. For example, if the business specialists use team creator to refer to the user who created a team, in the data model, we should also use team creator instead of other terms, such as team owner. And we should have a naming convention to enforce the consistency. We will talk about naming convention for data modeling later.
