    One example of how clustering could be applied to Thanksgiving is the type of eater you are. Variables could include what items they eat, portion size, number of helpings etc. to come up with clusters of people based on their eating habits.

    One use for a decision tree could be advertising. You could use age, gender, address, and many other factors to determine who will most likely purchase your product and who you should market to.

    I think that SpotCrime is an example of OLAP/Pivot table analysis. This information is probably being pulled from a larger dataset, but in this example, an OLAP/Pivot table analysis lets you to pull out the location and the crime and relate the two visually. By comparing the two, you can quickly see the crime committed in your area.

    This summer I worked at a resort golf course and we used a system called StarterHut to do the transactions. Occasionally a friend of one of the managers or one of the Resort’s business partners would come and play and their greens fees would be complimentary.

    I would also like to go over ERDs. I think the hardest part for me is knowing how each entity relates to others. Using what’s given in the scenario it can be hard to know what the correct ERD should look like.

    At Temple there are obviously many students enrolled in classes. For Temple to see who has taken a certain class they need to join the two data sets. By joining the student data and the class data, Temple can then look at the relationships like grade and credits earned between the two entities.

    I think the hardest part of creating an ERD is the cardinality. Even when it is given in the problem, it can be tricky finding the correct symbols to represent the situation. If it is not given then you have to analyze the scenario and figure out makes the most sense. Having to interpret the given information can be difficult and it’s hard know…[Read more]

    In my summer job at a golf course, at the end of the day we would make a sales report with the days data. From that we would organize it so that we could see which people (hotel guests, members, locals, etc.) are playing when. We would also look to see what merchandise is selling and figure out whether or not we should reorder it or something new.…[Read more]

    The most important takeaway from this class, for me, has been understanding the way that data is used in daily life. Data and information drawn from it is the reasoning behind everything we do from marketing, to exercising, to major business decisions. Data usage is growing and soon every person might have a personal database.

    A KPI I use here at Temple is the number of meal swipes and Diamond Dollars I have left. These both fit into the SMART criteria. They are specific in that there aren’t too many ways to interpret the data so it’s clear what it is measuring either the amount of swipes I’ve used or the current balance in my Diamond Dollar account. They are both…[Read more]

    I haven’t worked with excel too much so I haven’t really had the chance to make any of these mistakes but I think number three, backing up the original, is the most important. By backing up the file, if you make any of these other mistakes and ruin the file, you can just pull up the original spreadsheet and start over. Rather than going back and…[Read more]
