ne employee, the orders’ info such as order number, order date, ship date, and customer id and employee id are recorded. All customers’ information and employees’ information (i.e. customer’s first name, customer’s last name, employee’s first name etc.) ar e also stored. When each order is created, the products that customers ordered are checked in their current inventory in order to provide accurate order’s ship date estimation. If the product’s quantity on hand is less than the quantity ordered, then additional products are requested to vendors. For each request, product id, vendor id, wholesale price and days to deliver are recorded. All vendors’ information and product’s information (i.e., vendor’s name, product’s description, and product’s retail price e tc.) are also stored. The figure above shows the logical schema of Dallas WareHouse’s OLTP. The CEO of Dallas WareHouse Inc. wants a data warehouse that can capture one important business process. He would like to determine how much each customer order by week, month, and year, and how many orders are created by time periods. He is also interested in how many orders are made on weekends, and holidays. The figure below shows the date dimension table of Dallas WareHouse’s OLAP. Import CSV file from eCollege , and then create SSIS package solution that can perform ETL process to load data into your Date dimension table (10 points). Hint: DATEPART function and conditional statement can create most ETL date attributes.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
