The hardware and software for the computer system for the clinic must be able to support all the information requirement of the clinic and not only the requirements of its operations function. Render and Heizer said that in order to provide services, an organization undergoes three primary functions. These functions are marketing, operations (production in manufacturing settings), and finance (Render & Heizer 1998, p. 5). Although, the main concern of the new owner of the clinic is to be able to install a computer system which can support the requirements of its doctors and nurses, nevertheless it is but prudent to also design a computer system that can also handle the marketing and finance functions of the clinic.This paper aims to present that computer system and discuss the different issues related to it. Moreover, the computer system design presented and discussed in this paper incorporated the four primary factors that determine the value of information. These factors are information appropriateness, information quality, information timeliness, and information quantity (Certo 2000, p. 472). In other words, the information provided by the computer system herein designed is relevant; it highly represents reality, timely, and provides the decision maker information to make the right decisions.
Task 1: Computer Systems Design with a Web Server
Task 2: Operating System and Software Requirements
Task 3: Network Arrangement
Butler W. Lampson aptly stated that “[designing] a computer system is very different from designing an algorithm [as the] external interface (that is, the requirement) is less precisely defined, more complex, and more subject to change; [the] system has much more internal structure, and [the] measure of success is much less clear” (1983, p. 33). Hence, in this portion of the assignment, the student aims to lessen, or perhaps eliminate, the risk of the first complexity – the computer system more subject to change by enumerating the minimum requirements
[...] However, no matter how updated the clinic's antivirus is, it has no 100 per cent guarantee that its computer system will never be a victim of a virus attack. A personal computer-based operating system such as Windows Vista is always prone to virus attacks. Of course, backing up the computer system is an important task. Thankfully, the Windows Server 2008 has this functionality. Moreover, each of the ten computers can be individually programmed to create from time to time back up of the files stored in their memories. [...]
[...] The systems must be able to: support a variety of functions within clinical care, program monitoring and reporting, supplies and logistics, and research. As such these more complex systems need to be able to handle different types of data; accommodate new data such as drugs, clinical conditions and outcomes without modifying the data model; future data requirements are often not known at the start of the project and evolve during the lifetime of the system; allow for temporal data; data for clinical diagnoses, laboratory tests, treatments and outcomes are often temporal in nature, particularly for chronic disease management; allow for data to be exported in standard formats for analytic and statistical packages, third party software, etc.; and allow for or can gracefully expand to, support different spoken languages and variations in medical terminology.

[...] Some of these 100 reasons are: Windows Vista makes using the personal computer a breeze. “Windows Vista features a breakthrough design and easy-to-use organizational tools that make it simpler to get things done and get on with life! Find what you need instantly, on your PC or on the web, with Instant Search. Bring more clarity to your tasks with the spectacular Windows Aero user experience and Windows Flip 3D, A allowing you to see everything you're working on at a glance” (www.microsoft.com). [...]
[...] The presence of a redundant firewall is necessary for a system which contains very confidential information the unauthorized access and distribution of which can greatly damage the reputation of the clinic. Lastly, to ensure the security of the systems and of course, to safeguard the confidentiality of the clients records that the system houses, several measures can be adopted. These are: Requiring users to have complex passwords and coding their system access so they can only access the parts of the system they need. [...]
[...] Since it is quite expensive to maintain a web server, the idea of outsourcing it to host providers such as www.godaddy.com, www.hostmonster.com and the like can save money. These host providers offer features and tools that will help establish database management and file handling on top of hosting the site domain server Local area network (LAN) systems A LAN EMR or local area network electronic medical record system is deployed at a single site and the machines have a relatively fast connection to each other (Ethernet 10 base-T). Typically these systems revolve around a database (Oracle, MySQL, MS SQL Server) deployed on a central server. [...]
