Management Information Systems - Research Paper Example 1.4 MANAGEMENT INFORMATION SYSTEM The Management Information System is an application program designed to produce predesigned and predefined reports for the use of people responsible for the management. These reports are generally analytical information based on following parameters:- Periods: Daily, weekly, monthly, yearly and periodical. Trends: Upward, downward, straight. Movement: Fast, slow, normal Comparison: based on past and present data Age: Based on 30 days, 60 days, 90 days and older Exceptions: Based on if and then conditions. Chapter 2 Management Information System Development Phases Understanding the development process of MIS An information system is developed and designed by going through number of processes and phases. It is important to understand them so that we can asses the true value of the system on one hand and determine needs for improvement on the other hand.. An entirely new solution based on latest technology involves number of phases for planning, organiz ing, executing and controlling to achieve the required quality software. There are also constraints of time, money / budget and quality. The Management Information System is developed after going through the following phases: 2.1 REQUIREMENT GATHERING In this phase, all the users are interviewed for gathering information about the requirements, the existing software are studied simultaneously and details of the requirements are noted down. A Software Requirement Specification (SRS) document is prepared from the data collected has deliverables:- i. Business Requirements ii. Functional Specification iii. Non-Functional Specification iv. Use Case Diagram v. Usage Scenarios The above documents are formally reviewed in a meeting for discussion and final approval. 2.2 DESIGN AND ANALYSIS...

1.Phytochemicals Discussion .2.Foods and Cancer Prevention Essay

1.Phytochemicals Discussion .2.Foods and Cancer Prevention - Essay Example A group of phytochemicals are collectively called Flavonoids. These are compounds with varied chemical structures present in fruits, vegetables, nuts and seeds. The major flavonoid categories are flavonols, flavones, catechins, flavanones and anthocyanins. The main dietary sources of these compounds are tea, onions, soy and wine. The main flavonoid in onions is quercetin glucoside and the main flavonoid in tea is quercetin rutinoside. Flavonoid intake has been inversely linked with coronary heart disease in the Zutphen Elderly Study, the Seven Countries Study and a cohort study in Finland all of which have been reviewed and accepted by the American Journal of Clinical Nutrition and American Heart Association – both organizations that are highly credible. Also, the incidence of ovarian cancer may be reduced with increased consumption of dietary flavonoids, according to researchers from Brigham and Womens Hospital and the Harvard School of Public Health. The study looked at food intake surveys and ovarian cancer data from 66,384 participants in the Harvard Nurses Health Study, which collected health data from 121,700 women over a period of 30 years. This is the first prospective analysis of flavonoid intake and ovarian cancer incidence. (in Donovan, 2004) According to the article by Steinmetz and Potter (1996), there have been several studies trying to establish a relationship between vegetable and fruit consumption with the risk of cancer. After having compared the studies, it was established that the perceived benefits of eating vegetables and fruits especially with cancer protection was consistent in the studies. Asides from these, there are also associated benefits including protection against cardiovascular disease, diabetes, stroke, obesity, diverticulosis, and cataracts.
