How would you explain what you’ve learned to a future employer in a job interview?

The most important takeaway I got from the MIS 2502 course was how data and technology are constantly changing our lives. With the use of SQL and R, students in the class were able to discern how to effectively analyze, interpret, and display data in a way that e…[Read more]

A business question that you could answer using a decision tree is the factors that cause consumers to buy more organic options. In order to answer this question, I would need to collect data about the consumer’s monthly household income, the age of customers, the amount of individuals in the household, and the gender of the customer. In order to…[Read more]

A business question to be answered that we did not go over in class is within the context of a restaurant. The question would be, “Which customers ordered a certain dish in the months of June, July, and August.” The three dimensions would be Customer ID, the type of dish, and the time/month of the year. Instances of what could be measured through…[Read more]

An example where data is stored in different formats in two different sources is temperature.

As a result, in order to solve this issue, all the temperature data must be converted to…[Read more]

Is it similar to the in-class exercises we have done where we are creating ERDs from problem descriptions, developing queries based on certain needs, etc.? Will we also be tested on multiple-choice questions about definitions and certain concepts we learned in class?

There are numerous examples of where a join could be used on a set of tables. Netflix is a company that tracks tons of data and processes it in a way that allows them to deliver relevant content to paying members. As a result, one table might represent the “show” and another table would be labeled as “subscriber.” The join might be used to obtain…[Read more]

The most complicated thing about interpreting an ERD from a problem description is that everything is not always straightforward. The problem descriptions we receive in class are generally very self-explanatory and are not too difficult to construct an ERD out of. However, in the case of our homework assignment or a real-life scenario, everything…[Read more]

An example of where raw data is transformed into information is the Temple Student Feedback Forms. Students provide feedback on various teachers at the end of the semester based on their perception of how much they enjoyed the professor and the class. They input bits of information varying from ratings on the quality of the class to what could be…[Read more]
