5 Decision Support System Decision support system (DSS) pool models and data in an effort to solve problems with broad user involvement. The models are representations of reality that the DSS uses to come to a conclusion. Users can use the data and models to do sensitivity analysis, what-if analysis, and goal-seeking analysis (Rainer & Cegielski, 2010). By doing these analysis managers can manipulate the data to predict future sales and profits and make the necessary adjustments when needed. Electronic Commerce System Electronic Commerce System (ECS) enable organizations to conduct transactions, called business-to-business (B2B) electronic commerce, and customers to conduct transactions with businesses, called business-to-consumer (B2C) electronic commerce (Rainer & Cegielski, 2010). Electronic transaction systems allow customers to pay via a debit or credit card instead of writing out a check or paying with cash. The number of customers with cards is growing fast, without the use of electronic transaction systems the business would not be competitive in this market. ECS is even more crucial when dealing with B2B transactions, often times there is no face-to-face interaction with suppliers or business partners.

    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.
