MIS 665 Topic 3 DQ 2 By definition, simulations require a distribution to be specified (e.g., normal, Poisson). Many times, the exact distribution to be used is unknown, so it must be assumed. One argument against using simulations to perform risk analysis is that there is no real benefit because the set of assumptions is simply shifted from assumed parameter values to assumed distributions of parameters. Comment on this argument and justify your opinions with reasons, facts, and examples. G...

MIS 665 Topic 1 DQ 1 Forecasting techniques rely on the adage that history repeats ts itself. Many times, though, it has been noted that there is no guarantee that historical patterns will repeat and, even if they do, it can be difficult or impossible to predict when a pattern will repeat itself. Provide two time series examples that seemed stable and predictable until there was a significant change to the pattern. Was there a way to predict the pattern change? Explain. What is Forecastin...

MIS 665 Topic 1 DQ 2 Technically, once a time series model is built, any future value can be forecasted. For example, assume you built a model that forecasts monthly sales of a product given the last 3 months of sales. Using the model, you forecasted monthly sales for the next 6 months, and the model provided very accurate predicted sales. Your manager wants to use your model to predict sales for the next 5 years. What are some problems that could occur with extending the forecast horizon ou...

MIS 665 Topic 3 DQ 1 Before computers were widespread, almost all risk analysis was done without simulation. Therefore, only a handful of scenarios could be formulated to understand the risk of a decision. Typically, a best-case and worst-case scenario was determined and decisions were based on these two scenarios. What are some of the drawbacks of this decision-making approach? Specifically, how does the capability to summarize 1,000s of simulated scenarios improve the approach? Greetings...

MIS 660 Topic 1 DQ 1 Suppose you wanted to estimate the average household income of all Grand Canyon University (GCU) students. To expedite the process, you only gather household income data from all your friends who major in business at GCU. You then calculate the average income among your friends and report that it represents the average income of all GCU students. Is this a good approach? If not, how would you gather data to derive a better estimate? Explain your answer. To estimate the a...

MIS 660 Topic 2 DQ 1 Suppose you had daily temperature data indicating the "high" point of each day for 2015. If you want to show how the high differs over time, what are some of the plot types that will allow you do this? What are some benefits to binning the data into one of 52 weeks and plotting the average high for each week? Would it make sense to do something similar for the four quarters in the year? Why or why not? Binning is the process of transforming numerical variables into c...

MIS 610 Topic 8 DQ 1 You have employed several commonly used database automation tools in your work throughout the course. Discuss which of these tools has proven to be the most useful overall. Provide your reflective analysis with support from your work, an industry example, or the Topic Materials. The last eight weeks has been a great experience for me, I learned a lot from the discussion questions. However, one important tool that proven to be the most useful for me is the study materia...

MIS 610 Topic 4 DQ2 Determinism of a function is one of several properties of user-defined functions that determine the ability of SQL to index results. When and for what purposes would you choose to use deterministic versus nondeterministic functions to arrive at your desired results? Justify your ideas with support from the Topic Materials or relevant industry examples. A deterministic function is one that will always provide the exact same result to you, whereas a nondeterministic funct...

MIS 610 Topic 6 DQ 2 Some consider SQL to be an ORDBMS due to several recently implemented features it provides, but most consider it an RDBMS. Oracle once touted itself as an ORDBMS in Release 8, but later retracted that statement in Release 8.1 (while retaining key desirable organizational features). What programs are actually considered “object based”? Select a specific program and explain both its functionality and advantages to a business. Justify your ideas with support from the Top...

MIS 610 Topic 5 DQ 2 Describe four key features of an object database management group (ODMG) and what makes this technology so appealing for so many different types of users.

MIS 610 Topic 6 DQ 1 Of the two object-capable data programming methods, what attributes of object relational design make it the more preferred method? Justify your ideas with support from the Topic Materials or relevant industry examples. Object-oriented database management systems (OODBMSs) combine database capabilities with object-oriented programming language capabilities. This allows object-oriented programmers to develop the product, store them as objects, and replicate existing obje...

MIS 610 Topic 7 DQ 1 Referring to the topic reading “Whatever Happened to Object-Oriented Databases?”, do you agree with the position that an object-oriented database is a niche market?
