High-Level Overview of Information Systems : Avoid a common mistake: You cannot buy IS, because you cannot buy people or processes. However you can buy IT: o Buy or lease hardware, license programs and databases, even obtain predesigned procedures. Ultimately, people execute those procedures to employ that new IT. Any new system requires training tasks, overcoming employees’ resistance to change, and managing employees as they utilize new system. Social Media and Business: Social media allows people to get social online by sharing opinions, news, content, photos etc. Digital Persona and Business: One of the biggest challenges (but ways of being innovative) is defining the digital persona of social media mediated business This is the ultimate objective that businesses face Substance over norm: The biggest challenge is figuring out how to use social media to drive business strategy. Information Systems Elements: Data & Information Information System: o Set of interrelated components o Collect, process, store, and distribute information o Support decision-making, coordination, and control Information Systems Elements: o Hardware o Software o ICL (People): Knowledge, skills, trainings, etc. o Procedures o Data Data versus Information: o Data are streams of raw facts o Information is data shaped into meaningful form Example: Raw data from a supermarket checkout counter can be processed and organized to produce meaningful information, such as the total unit sales of dish detergent or the total sales revenue from dish detergent for a specific store or sales territory. A “Systems” Perspective of IS: Three core activities of information systems: Input : Captures raw data from organization or external environment Processing : Converts raw data into meaningful form Output : Transfers processed information to people or activities that use it

    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.
