Case Study: Database Development Read the following articles available in the ACM Digital Library: Articles are attached as PDF Dual Assessment of Data Quality in Customer Databases, Journal of Data and Information Quality (JDIQ), Volume 1 Issue 3, December 2009, Adir Even, G. Shankaranarayanan. (attached as PDF) Process-centered review of object oriented software development methodologies, ACM Computing Surveys (CSUR), Volume 40 Issue 1, February 2008, Raman Ramsin, and Richard F. Paige. (attached as PDF) Write a two to three (2-3) page paper in which you: Recommend at least three (3) specific tasks that could be performed to improve the quality of datasets, using the Software Development Life Cycle (SDLC) methodology. Include a thorough description of each activity per each phase. Recommend the actions that should be performed in order to optimize record selections and to improve database performance from a quantitative data quality assessment. Suggest three (3) maintenance plans and three (3) activities that could be performed in order to improve data quality. From the software development methodologies described in the article titled, “Process-centered Review of Object Oriented Software Development Methodologies,” complete the following. Evaluate which method would be efficient for planning proactive concurrency control methods and lock granularities. Assess how your selected method can be used to minimize the database security risks that may occur within a multiuser environment. Analyze how the method can be used to plan out the system effectively and ensure that the number of transactions does not produce record-level locking while the database is in operation. Your assignment must follow these formatting requirements: Be typed, double-spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions. Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length. The specific course learning outcomes associated with this assignment are: Prepare database design documents using the data definition, data manipulation, and data control language components of the SQL language. Describe the basic mechanisms for accessing relational databases from various types of application development environments. Explain the key principles of data security and identify data security risk and violations in data management system design. Use technology and information resources to research issues in the strategic implications and management of database systems. Write clearly and concisely about topics related to the strategic planning for database systems using proper writing mechanics and technical style conventions.

Assessing Cost-Benefit and Utility in SelectionGiven the volume of jobs that need to be filled, the difficulty in filling specific positions, and the potential impact of making poor hiring decisions, companies should strategically plan how to recruit and select employees. Such planning will ensure the amount of effort is cost effective and achieves the desired results. Consequently, many organizations today engage in such planning by conducting cost-benefit and utility analyses to ensure the requisite amount of effort is dedicated to obtain the desired results (Boudreau, 1990; Bodreau & Ramstad, 2002). In the long term, these analyses may save organizations time, money, and effort. On the other hand, it is also important to consider the potential impact of poor hiring practices not only on the company, but also on the unsuccessful applicant or the new hire that does not work out.For this Assignment, review this week’s media and the personnel selection processes that you developed for your Week 3 Assignment. Consider the cost benefit and utility of the personnel selection process for each job type.Develop a cost benefit analysis and a utility analysis for a personnel selection process for the three job types presented in the media (manufacturing, sales, executive). Your Assignment should specifically detail the following: The resources required (e.g., cost, personnel, time, etc.) for each job type The benefits and drawbacks of each component of the personnel selection process (e.g., application, interview, testing, etc.) The impacts of the applicant pool, the number of openings, and the projected volume of applicants for each job type Justifications for the personnel selection process to be used for each job type You should also provide an APA reference list and use appropriate APA citations throughout your assignment.Submit by Day 7 your 5- to 7-page paper including both analyses.

This is a discussion posthttps://ambassadored.vitalsource.com/#/books/97813...For your initial post, you should write two full (5-6 sentences each) paragraphs as described below:Paragraph 1: As you finish your last module in Modern World Literature, select your favorite story from the readings to discuss in a paragraph for the initial post to the forum. Use your biographical notes from this module, your text, or the Internet to look up facts about your chosen author. Think about the following questions as you make your selection:What is the theme of your story?What was culturally significant about the events and time period of your chosen piece?How did the author use his/her background to craft the characters or setting?How would this story have been different if written from a mainstream cultural perspective?What impact did this story have on your understanding of the author’s cultural experiences?Paragraph 2: In 5-6 sentences, summarize your ideas and experiences with what you have read and watched (the films) in this course. For example:Did you discover a favorite new author? Were you surprised by any of the styles of writing that you read? What film was your favorite? Did you like having films included in the readings?Which style of literature was your favorite and why? (Select from magical realism, modernism, post-modernism, post-colonialism, minority literature, feminist literature, mystery). You may include commentary on the novel in this section as well as that fits both post-modernism and the mystery genre categories.
