What are the four major components of a Business Intelligence (BI) system?

1. Data warehouse (with its source data) 2. Business Analytics (collection of tools for manipulating, mining, and analyzing the data in the data warehouse) 3. Business Performance Management (BPM) for monitoring and analyzing performance 4. User interface

Managers usually make decisions by following a four-step process. What are the steps?

1. Define the problem 2. Construct a model that describes the real-world problem 3. Identify possible solutions to the modeled problem and evaluate the solutions 4. Compare, choose, and recommend a potential solution to the problem

List and describe three levels or categories of analytics that are most often viewed as sequential and independent, but also occasionally seen as overlapping.

1. Descriptive - Knowing what is happening in the organization and understanding some underlying trends and causes of such occurrences. 2. Predictive - Aims to determine what is likely to happen in the future. 3. Prescriptive - Goal is to recognize what is going on as well as the likely forecast and make decisions to achieve the best performance possible. It provides a decision or a recommendation for a specific action.

List four of Mintzberg's Decisional roles of managers.

The environment in which organizations operate today is becoming more and more complex. Business environment factors can be divided into four major categories. What are these categories?

1. Markets 2. Consumer Demands 3. Technology 4. Societal

Describe the types of computer support that can be used for structured, semistructured, and unstructured decisions.

1. Structured decisions are possible to abstract, analyze, and classify in specific categories. The computer support used is generally as quantitative formulas. A model and solution approach is developed and also scientific approaches are possible for the decision making. 2. Semistructured problems may involve a combination of standard solution procedures and human judgement. Management science can provide models for the structured portion of the problem while a DSS can support the unstructured portion. 3. Unstructured decisions can only be partially supported by standard computerized quantitative methods. For the most mart, a customized solution must be developed. A DSS is often used for these decisions.

33) Business intelligence (BI) can be characterized as a transformation of A) data to information to decisions to actions. B) Big Data to data to information to decisions. C) actions to decisions to feedback to information. D) data to processing to information to actions.

A) data to information to decisions to actions.

How does Amazon.com use predictive analytics to respond to product searches by the customer?

Amazon uses predictive analytics by using the information composed from big data to personalize the shopping experience for customers. The offer recommendations for products based off of what the customer has viewed previously (propensity to buy/customer segmentation). They also have fraud detection in place to create a fast and safe way to make purchases through their app/website.

Describe and define Big Data. Why is a search engine a Big Data application?

Big data is data that cannot be stored in a single storage unit. It arrives in many different forms and are stored in chucks on different machines connected by a network.
