Part 1:Discuss the possible data request scenarios in a distributed database environment.Part 2: Respond to a post below“Let’s discuss the data request scenarios one by one:1. Single request accessing a single remote database:This is a basic scenario in which a single SQL statement is directed to a single remote DBMS, also known as a remote request.2. Multiple requests accessing a single remote database:In this scenario, a single unit of work consists of multiple SQL statements directed to a single remote DBMS. The user can define blocks of the work using commit, rollback and save, but the remote DBMS managed the processing of this unit of work.3. Multiple requests accessing multiple remote databases:In this case, a unit of work may be composed of multiple SQL statements directed to multiple remote DBMSes. However, any one SQL statement may access only one of the remote DBMSes. Similar to the second scenario, the local user defines the units of work using commit, rollback, etc., but the remote DBMS to which the SQL statement was directed manages the unit of work’s processing. In this scenario, a two phase COMMIT must be used to coordinate COMMIT processing for the multiplelocations.4. Multiple requests accessing any combination of multiple remote DBMSes:In this scenario, a unit of work now may consist of multiple SQL statements addressed to multiple remote DBMSes, andeach SQL statement may address any combination of databases. Similar to the previous scenario, the local user defines the units of work using commit, rollback, etc., but the remote DBMS to which the SQL statement was directedmanages the unit of work’s processing. A two phase COMMIT must be used to coordinate COMMIT processing for the multiple locations.”Part 3:1. How does data mining work? Discuss the different phases in the data mining process.2. Describe the characteristics of predictive analytics. What is the impact of Big Data (social media) in predictive analytics?Part 4: Watch the video below and answer the questionsPlease view the video associated with this threadBased on what the presenter shares during the video, please share your idea of the following:1) a future one-way ANOVA investigations possibility that may provide additional insight to this discussion. In your post, please may specific references to the presenter’s remarks.2) one experimental design component that you noticed. Be specific by stating what specific aspect of experimental design you are referencing and the specific example presented in the videoPart 5: Respond to a post below:“The speaker explored the concept of “reasoning” Interpreting why is an important design component of this experiment. When interviewees are asked to explain their choices, they tend to reconstruct and fabricate the reasons for their original choices without realizing that the answers have been replaced. The shift in interviewees’ decisions was done by magic to manipulate the consequences of people’s choices – and then to measure why and how people felt about those changes. The conclusion can prove the hypothesis of the experiment, which has implications for the nature of self-knowledge and how people respond to manipulation.”

Managing Markets: Cloud ComputingIn this assignment, you will examine the effect of management innovation on a firm’s ability to effectively adopt an emerging technology. Using the example of cloud computing, you will apply the ideas you learned in Week 2 to discuss the adoption patterns for new technologies and opportunities to deploy them.Tasks:From the South University Online Library, read the following paper:Management Innovation and Adoption of Emerging Technologies: The Case of Cloud ComputingOn the basis of your reading, address the following:Discuss the objectives and main findings of the paper. Discuss the background, decision-making goals, and challenges addressed in the paper.Describe the architecture, methodology, and features that pertain to the technology in the paper.Identify the most important barriers to greater use of the technology.Discuss whether a firm would create more strategic value by developing and deploying this technology or whether it would do so by pushing the barriers of a known, more conservative technology.Discuss the forces shaping a commercialization strategy for this technology.

Through the use of currently available online tools and search facilities, ordinary users can easily acquire personal information about others. In fact, anyone who has Internet access can, via a search engine such as Google, find information about us that we ourselves might have had no idea is publicly available there. (a) Is it true that individual privacy is threatened by the use of search engines? (b) Give some examples how that might occur. (c) Do individuals/hackers from anywhere on the globe access personal information of citizens of other countries? (d) Give some examples illustrating that has occurred. (be specific and provide support for your answer) Please elaborate (beyond a yes or no answer) and provide your “theoretical” rationale in support of your responses. (comprehension)
