91.4904 Assignment 1 Due: Tuesday Jan 27, 2004 Reverse engineer the Northwind database. Create a logical ERD from which Northwind could be generated. Design a dimensional model for Northwind. Create a logical ERD; do not implement your database at this time. For each metric, specify if its additive, semi-additive, or non-additive. Do not use snowflaking. For each dimension, state the normal form it is in. Specify the attribute hierarchies present in each dimension. For both ERDs, use the Peter Chen notation.
