CST 4704 Final Project

Data Warehouse for International Inc.

Business Processes

1) Customers This process is used to track the guests of the hotel.

2) Maintenance- This process maintains the equipment of the hotel.

3) Inventory This process audits the equipment needed and identifying what the hotel currently has on

hand.

4) Retail This process is used for sales of products within the hotel.

5) Employees This process is used to track the hotels current employees.

6) Services - This includes the rooms currently in use or available for our customers and room service for

dinning.

7) Wholesale Vendors - This tracks equipment purchased from other companies in order to run the hotel

successfully.

Executive Reports

1. An executive requires a report to display all of the items in stock in the hotel (which are sold by our in-

house retailers) as well as the wholesale costs and margins (via as AS statement in our SQL). This will

be used to visualize and evaluate trends in vendor pricing so we can adjust the markup on various

items that are in high slow but slow moving, and create initiative for sale promotions.

2. Executives would want to know the dates/seasons that result in the most check-ins, and the customer

information for the most number of check-ins. This would be used to form a basis for a loyalty and

rewards program, and see if the retention rate would increase.

3. Executive would list outstanding products (that were ordered and not delivered within a 20 day

timeframe.) This would be used to prune vendors and determine alternative solutions to resolve the

demand/vendor issues.

4. Executives must know the fluctuation attendance rates for and spring break, in our hotel chains for the

analysis of margin shifts in room prices.

5. Executives need to know inventory reports for such items as Eyewear, Glassware, etc. To know when

to restock and adjust margins. This can be produced in a flexible manner via SQL pulling from our

warehouse.

6. Executives require to know the status of our vendor contracts, in which we will create a statement to

show which vendors whom have less than 5 days remaining in their lease.

7. Executives need to know the status of our service contracts, and we can create a statement to show

which vendors have less than 10 days remaining in their contract end date, and display the rep

information for contact.

8. Executives will need to know employee information for employees who have has the longest tenure

and also have a salary greater than $40000 and benefits are given.

9. Executives request to see the on-hand quantity of inventory and sorted by date, alphabetically, type,

and level. This is needed to express this information to different departments that deal with inventory

(stock workers, managers, employees, etc.)

10. Executives request a list of regular customers who have not checked in for an extended period of time,

which would fall within 30 days in order to send them a promotional message.

Data Warehouse Design Steps 1) Step One: Identifying the Business Process

The first step of designing a Data Warehouse is identifying the business processes. A process is a natural business activity that is performed in an organization that is typically supported by a source data system or systems. Although, a business process is not considered a business department. Business processes are typically an organization wide activity. It is recommended to build the Data Warehouse based on the business processes in the company rather than departments. With International Hotel Inc. the business processes that weve identified are customers of the hotel, maintenance of equipment, inventory on hand, retail sales, employees, services of the hotel, and vendors of hotel equipment.

2) Step Two: Define the Grain of the Business

The second step, we are required to specify what exactly is represented in one row of our fact table. International Hotel Inc. will monitor the items in stock of the hotel, the amount of check-ins during a period of time, products not delivered within a specific timeframe, fluctuations of attendance, inventory reports of their retail sales, vendor and service contracts, employee information, on hand quantity of products, and a list of regular customers whom have not been attending.

3) Step Three: Choose the Dimension

In this step, we need to identify all the specific and detailed data that will then represent the user requesting the data with information used for analysis and reporting. This is vital when identifying trends within an organization For International Hotel Inc. we have identified five dimensions. Our customers dimension includes information of current customers such as their name, address, phone, email, a unique customer ID, as well as the service or product theyve ordered. With our inventory/retail dimension, it is detailed with the SKU#, the product, price, as well as information of the quantity the hotel has on hand and information of the order. The employees dimension includes basic information such as their name, address, email, phone, a unique employee id, as well as their job title, benefits, and salary. Our services/maintenance dimension includes a contract id, the service representative, and information on the contract. Lastly, our Vendors dimension includes the Vendor ID, their address, and product information.

4) Step Four: Identify the Fact Table

The fourth step involves designing the data warehouse and quantitative data that will need to be identified for analyzing and reporting. This is necessary for businesses that rely on statistics and their sales. International Hotel Inc.s fact table lists information of their sales of rooms and retail items for specific months, shipping costs, and promotional numbers.

SQL Statements

An executive requires a report to display all of the items in stock in the hotel (which are sold by our in-house retailers) as well as the wholesale costs and margins (via as AS statement in our SQL). This will be used to visualize and evaluate trends in vendor pricing so we can adjust the markup on various items that are in high slow but slow moving, and create initiative for sale promotions.

SELECT SKU_NUM, PRODUCT_NAME, PRICE, (100 * (PRICE - WHOLESALE)) / PRICE AS MARGIN FROM INVENTORY ORDER BY MARGIN DESC

Executive would a list of outstanding products (that were ordered and not delivered within a 20 day timeframe.) This would be used to prune vendors and determine the ways to resolve demand/vendor issues.

SELECT SKU_NUM AS SKU, PRODUCT_NAME AS PRODUCT, DESCRIPTION, PRICE, INV_DATE, DATE_ORDERED, BACKORDER, INV_DATE - DATE_ORDERED AS OUTSTANDING FROM INVENTORY WHERE INV_DATE - DATE_ORDERED > 20 ORDER BY OUTSTANDING DESC;

Executives would want to know the dates/seasons that result in the most check-ins, and the customer information for the most number of check-ins (for example in April due to spring break). This would be used to form a basis for a loyalty and rewards program, and see if the retention rate would increase.

SELECT CUSTOMERID, FIRST_NAME, LAST_NAME, PHONE, EMAIL, CUST_DATE, PRODUCT_NAME, DESCRIPTION FROM CUSTOMERS WHERE PRODUCT_NAME LIKE 'RM%' AND CUST_DATE BETWEEN TO_DATE('01-APR-13') AND TO_DATE('30-APR-13') ORDER BY LAST_NAME;

Executives would want to know the fluctuation attendance rates for and spring break (April 14 to April 18), in our hotel chains for the analysis of margin shifts in room prices.

SELECT CUSTOMERID, FIRST_NAME, LAST_NAME, PHONE, EMAIL, CUST_DATE FROM CUSTOMERS WHERE CUST_DATE BETWEEN TO_DATE('14-APR-13') AND TO_DATE('18-APR-13');

Executives would want to know inventory reports for such items as Eyewear, Bath, Glassware, etc. To know when to restock and adjust margins, this can be produced in a flexible manner via SQL pulling from our warehouse.

SELECT SKU_NUM, PRODUCT_NAME, QTY_ORDERED - QTY_ON_HAND AS UNITS_SOLD FROM INVENTORY WHERE CATEGORY = 'Bath' or CATEGORY = 'Eyewear' ORDER BY UNITS_SOLD DESC;

Executives would want to know the status of our vendor contracts, we can create a statement to show which vendors have less than 5 days remaining in their lease.

SELECT VENDORID, VENDOR_NAME AS VENDOR, ROUND((CONTRACT_DATE - SYSDATE)) AS DAYS_RENEWAL FROM VENDORS WHERE ROUND((CONTRACT_DATE - SYSDATE)) 25000 AND BENEFITS IS NOT NULL;

Executives would want to know employee information for employees who have has the longest tenure and also have a salary greater than $20000 and benefits are given.

SELECT EMPID, LAST_NAME AS L_NAME, FIRST_NAME AS F_NAME, BENEFITS, SALARY, ROUND((SYSDATE - START_DATE)) AS TENURE FROM EMPLOYEES WHERE SALARY > 20000 AND BENEFITS IS NOT NULL ORDER BY L_NAME;

Executives would like to see the on hand Quantity of Inventory that is sorted alphabetically, by date, by type, and by level. This is needed because of the need to express this information to different departments that deal with inventory (stock workers, managers etc).

SELECT SKU_NUM, PRODUCT_NAME, DESCRIPTION, PRICE, INVENTORY.CATEGORY, VENDOR, INV_DATE, QTY_ON_HAND, QTY_ON_ORDER, BACKORDER FROM INVENTORY ORDER BY QTY_ON_HAND, CATEGORY;

Executives would want to know a list of regular customers who have not checked in for an extended period of time, which would fall within 30 days (between January 2013 and February 2013) so that the hotel may send them a promotional message.

SELECT CUSTOMERID, FIRST_NAME, LAST_NAME, PHONE, EMAIL, CUST_DATE
