Answer to Question 1

Answer: TRUE

Answer to Question 2

The star schema is a simple database design. Dimensional (or descriptive) data are separated from fact or event data. The star schema consists of a fact table, which contains event data as well as links to dimensions. Dimension tables contain descriptive information. For example, we might have a dimension for sales territory which would have a unique ID as well as several levels of granularity. There might be a territory description, state, city, zip code, etc. The dimension key is also in the fact table. In this way, it is fairly simple to look up information and do some drill-down type queries.
