i) First construct a Data Warehouse Bus Matrix to identify the company's business processes and any likely Data Marts.

iii) Create the table with a row for each fact table in your design, indicating the granularity of each fact and a brief justification for selecting that granularity.

iv) Create the table with a row for each dimension table in your design, giving a brief justification for selecting that dimension, and indicating any attribute hierarchies which exist within the dimension.

v) Create the table with a row for each design feature you have used, such as handling of possible null foreign keys, and the inclusion of any fact-less fact tables, degenerate dimensions, role playing dimensions, junk dimensions, outriggers, mini-dimensions, or any other design techniques discussed in the lectures.
