About five years ago, Facebook was involved in a multimillion-dollar effort to move a terabyte of data from a near-capacity data center to a then new higher-capacity data warehouse. The project was scheduled to be completed in 100 days with no provision for any schedule delays. In Facebook terms, a terabyte is equivalent to 250 billion “Likes” on Facebook.
The project had two phases, i.e., building and outfitting the new data warehouse, and then moving data to the warehouse. The new data warehouse was designed so the servers could handle four times as much data as the current servers, and the processors and software were upgraded as well. As a result, the new data warehouse could hold eight times more data than the current data center, and it could also move and manage data more efficiently. To reduce the risks the project team took a…

- As the head buyer for a major supermarket chain, you are constantly being asked by manufacturers and distributors to stock their new products. More than 50 new items are introduced each week. Many times, these products are launched with national advertising campaigns and special promotional allowance to retailers. To add new products, the amount of shelf space allocated to existing products must be reduced or items must be eliminated together. Develop a MIS report that you can use to estimate the change in profits from adding or deleting items from an inventory. Your analysis should include input such as estimated weekly sales in units, shelf space allocated to stock items, total cost per unit, and sales per unit. Your analysis should calculate total annual profit by items and then sort the rows in descending order based on total annual profit.arrow_forwardInformation systems professionals help organisations optimise and manage data processing and storage to boost efficiency.
