Fitchwood Insurance Company, which is primarily involved in the sale of annuity products, would like to design a data mart for its sales and marketing organization. Presently, the OLTP system is a legacy system residing on a shared network drive consisting of approximately different flat files. For the purposes of our case study, we can assume that 30 different flat files are going to be used for the data mart. Some of these flat files are transaction files that change constantly. During that time, the flat files are copied to another server, an extraction process is run, and the extracts are sent via FTP to a UNIX server.
Julie Sasso, 28, Beavercreek, Ohio. In primary and secondary school, teachers spend a good amount of time helping their students learn how to write, and as the student gets older, skills taught for writing become more complex and advanced. The process of learning how to write continues in the university, but students are pretty much left to their own devices to learn this process. This is rather unfortunate because writing is one of the most important skills required for success academically and professionally. Thats why its important to find helpful writing resources. Once such resource that comes to mind is AcaDemon.com, which describes itself as an online platform for publishing and disseminating academic content. AcaDemon is indeed just that вЂ“ its a site that can not only provide great research material but it also can provide really high-quality papers that students can use as examples to help them write their own papers. Odd as it may sound, Ive actually been in the position where Ive directed my doctoral students to AcaDemon for research purposes and, in previous years, directed some of my undergraduate students to AcaDemon so that they could find quality examples of the same types of papers assigned in class. AcaDemon carries papers on an abundant number of topics as well as offers a variety of paper types. All of my students were grateful for the hint about AcaDemon. They claimed it saved them time and provided badly needed assistance. The only caution I issued to my students when using AcaDemon or any similar site is to make sure that they dont cross the line between using the site for valid research and writing assistance and plagiarizing someone elses work. I think, when used responsibly, AcaDemon can be, and is, an extremely valuable online writing resource and I have no qualms about recommending the site to my students. On the contrary, Im happy to do so. If I were to review AcaDemon and give the site a grade, it would be an A+.
