Design and implement a simple data warehouse environment with star schema, data warehouse structure

You are a BA that is employed by a multinational professional services ([login to view URL] ) firm on the basis of some work you did in ICT394 as a student. You have been contracted out by your employer to a company that sells a large range of random items, called Omnibenchmark Pty Ltd.

You have been tasked with creating a data warehouse so Omnibenchmark can analyse their sales in order to assist with their management decision making, in particular, they wish to be to answer the following questions:

- Total of sales of each product by Year/Month/Week/Day

- Total sales of products by supplier by Year/Month/Week/Day

- Total sales by branch by Year/Month/Week/Day

- Total sales of product by branch by Year/Month/Week/Day

- Total sales by sales clerk by Year/Month/Week/Day

- Total sales by product by sales clerk by Year/Month/Week/Day

- Total sales by product type by sales clerk by Year/Month/Week/Day

You have been given access to three data sources from which you will need to draw your data. Below are the sources and the tables within them that are/may be of interest to you. These are discussed below (Primary Key, Foreign Key):

Source 1: Human Resources Database

The Human Resources (HR) database contains data about the people who are employed by Omnibenchmark. You have been granted access to a VIEW that includes the data you may need for the various analyses required. It only includes details of employees currently employed by Omnibenchmark in a Sales-related position. The view has been supplied to you as a text file.

The VIEW is called viewEmployee and has the following columns:

viewEmployee (EmpID, LastName, FirstName, DateStarted).

Source 2: Inventory System Database

The Inventory System maintains stock levels for all products sold by Omnibenchmark as well as the details of the Supplier. The data are stored in a proprietary system to which you have not been granted access. However, an export of two of the tables has been performed for you and supplied as an Excel file. The two tables are the Product table and the Supplier table. They are structured as below:

PRODUCT (ProductNum, ProductName, SupplierNum, ProductType)

SUPPLIER (SupplierNum, SupplierName, Country)

Source 3: Sales Database

The Sales database is an oracle database (luckily for you, it’s hosted on [login to view URL] and owned by SICT394AssignTL – you have SELECT privileges on these tables)

SALE (SaleID, ClerkID, CustomerID, SaleDate,)

SALE_LINE_ITEM (SaleID, LineID, ProductID, ProductPrice, Quantity)

SALE_CLERK (Clerk_ID, Clerk_Name, BranchID)

CUSTOMER (CustomerID, FamilyName, GivenName, Address, Suburb, State, PostCode)

PRODUCT (ProductID, ProductName)

BRANCH (BranchID, BranchPostCode)

What you have to do:

Task 1: Based on the list of questions the client wants answered (see above), discuss what you see as being the most appropriate level of granularity for your data warehouse. Your discussion will need to explain why you have made this choice, and why the alternatives have been discarded. This should take not more than one (1) page.

Task 2: Based on your answer to Task 1, design a Star Schema that will support the analyses as listed above.

Task 3: Create the data warehouse structure on arion:

- Create the Dimension tables, but only include the primary key (i.e., there is no need to create the other columns in the dimensions tables, just the primary key column)

- Create the Fact table(s) which should contain the following:

o Foreign key columns (and constraints) referring to the Dimension tables

o Measure columns
