Granularity of data refers to the level of detail of your data within the data structure. The higher/ finer your granularity is, the more data you have to store (of course with more detail). To aggregate data you obviously need the same granularity. And granularity will determine what kind of information (reports, etc.) you can create/ get out of your database.
