    The key takeaway from this course is the foundation in database and analytical tools (MySQL, R and its libraries, Pivot Tables in Excel) which can be built upon in other classes and in self-study. I feel much greater confidence and involvement with the MIS field, and can imagine myself exploring these tools and take on increasingly complicated…[Read more]

    A scenario where clustering can be incredibly useful is when a mall wants to divide customers into groups to study how to organize its organization of retail space. The type of stores where they make purchases, how much a consumer paid (if possible), and the time between purchases, and other variables can be used in a cluster analysis. The result…[Read more]

    A decision tree could be used to find out whether a customer or a group of customer is willing to purchase or try out the new product. The firm may have already collected data on what products or categories a customer bought, their usage volume, whether the customer has signed up for special membership. The company can perform decision tree…[Read more]

An example of R utilization is that of Data Song, a marketing analytics company, used ScaleR – a package from Revolutionary Analytics – to process big volumes of data simultaneously on different servers.

    SpotCrime is likely based on OLAP/Pivot Analysis due to the results it presents. After entering the address, the user sees a map and a crude table below showing the location, types, and other details of the most recent crimes in the neighborhood. However, this is simple an entry-by-entry representation of past incidents, grouped by categories and…[Read more]

    An example of this is how Vietnamese names may be stored differently in a US database and a Vietnamese database. A Vietnamese name can be three or four words long. A first name can comprise two separate words. However, many US online forms, which reflect their databases, limit first and last names to one word. This leads to potential mismatch…[Read more]

    I really like this Gender Wage Gap graphic for its simplicity, comprehensiveness and ease of use. The graph tells the story of wage inequality with only 5 colors and through simple flat lines. It makes the career categories bold, so as to save the space usually consumed by clutter-prone hierarchies. The interactive elements (pop-up information,…[Read more]

    This is my example for such a situation: I have a table for political data (political systems, current ruling party, etc.) in each country of the world. I have another table for each country’s economic metrics (GDP, GDI, debt, etc…). By using the join on these tables and applying necessary WHERE BY functions, I can figure out the GDP growth of…[Read more]

    I think the trickiest part about creating an ERD from a problem description is to avoid overthinking the situation, which may lead to listing entities irrelevant to the problem description or giving entities attributes they don’t have. This is because the way I approached ERDs back in MIS2101 was an open, unstructured one; I just came up with as…[Read more]

    When competing in the Alexion Analytics Challenge last semester, my teammates and I collected diabetes statistics (raw data) and nutrition intake (raw data) for countries and unique territories. These data on their own did not help us gain any insights into the global diabetes situation. By sorting the diabetes prevalence rate and calculating the…[Read more]

    I have worked with Excel before, but I have not used it for any data-intensive operations or tasks that require complex functions. Therefore, I have not fallen into the traps in the list yet. However, I have made mistakes that have element of number 2 and number 3.

    I used to work for a non-profit organization. I interacted a lot with data…[Read more]

    I believe that among the eight core principles mentioned by Stephen Few, “Simplify” is the most important one because it allows visualized data to be noticed and digested in an age where data are so plentiful that we spend less time on each set of data. Social media platforms provide good examples. On many occasions, we scroll quickly through our…[Read more]
