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. [...]

[...] Figure 2 General Structure of the Clinic Appointment System Source: Erdem, Demirel and Onut 2008, p Erdem, Demirel and Onut further stated that this patient appointment system can help the clinic prevents the usual problems that are encountered in a clinic. Some of these problems are: ?Long patients wait time will occur at the front desk of the clinic, ?Patients might be conveyed to wrong services [or wrong doctors], ?Large number of patients waiting to be served at the clinic will result in uncomfortable conditions such as congestion, noise, and poor ventilation, sound scheduling will not be performed due to incorrect examination times [which will also result to scheduling problems for the clinic's equipment], ?Patient appointments will overlap, ?Number of patients admitted within a working day will cause overtime for doctors, ?Doctors' and patients' dissatisfaction will create a tense environment at the clinic, ?Patients could prefer another health clinic due to improper management, and ?Doctors could be hired by other clinics or quit working? (Erdem, Demirel & Onut 2008, 2). [...]
