The business has contracted our firm to assist in setting upmore of the business’s various computer-based information systems.The next computer-based information system that the business is interested in is a Decision Support System (DSS) utilising Microsoft Excel (any version from Excel 2007 to current). The DSS will be used to analyse sales trends for the business to determine future courses of action for the business.Dr Nikola Tesla would like the information in the Database Management System (DBMS) (Assignment 1) imported into Microsoft Excel (any version from Excel 2007 to current) so that the information can be summarised as a report and some future analysis of sales trends performed. The suppliers used by the business, source items from either Luxembourg (LU) or Tuvalu (TV). They allow the business to select from either of these two regions on an ad hoc basic depending on the mostfavourable exchange rate at the time. Dr Nikola Tesla has noted that a number of the business’s competitors are providing a discount to customers who place large orders. The business would like to see what affect adopting a similar policy would have on the business. The business has also noted a growing number of online businesses are starting to provide free freight delivery as a way of encouraging more online business; the business would like to run a number of scenarios based on potential Mark-up and Freight options to ascertain the best combination for the business if they were to adopt this policy too. All phases in this project must be developed with professionalism and user-friendliness in mind.www.steampunktribune.com, Karl Edwards Studios. CIS1000 Assignment 2 QuestionPage 2
