Refer to the instructions from Module 1 for creating a database. Modify those instructions to create a database which you will name “Northwind_DW”. Once the database is created, capture a screenshot of the tree-type structure on the left side of PostgreSQL window to confirm that the database was created correctly. Submit the screenshot as part of the assignment deliverables.

Part II: Create the Customer Dimension Table

Using the Entity-Relationship Diagram below, construct and execute the SQL commands to create the Customer dimension table you will name “NW_Customer_DIM”. Review the SQL commands CREATE TABLE and ALTER TABLE. If necessary, refer to the SQL commands in the northwind.postgre.sql file, used in Module 1, for creating tables and altering tables to apply constraints.

NOTE: For this assignment, assume that all of the variables and their attributes from the source OLTP Customers table will be used in the NW_Customer_DIM table. Normally, only a subset of the variables from the OLTP source are loaded into a data warehouse. Which variables from the source that should be loaded into the data warehouse are driven by business questions and business needs? Capture a screenshot of the created table and a listing of your SQL commands.
