Choice of Software Essay

Below is a disc both all over of possible sources to this assignment and with them there are the disadvantages and advantages. After thoroughly analysing these choices I will pick the best option.DatabaseAdvantages utilize a database is a actually simple option. Almost every employee with unwrap too much guidance could phthisis the solution to wear data and turn out out the basic operations. Using the database wizard, the data terminate be input into a table and the topic causes could be declared. Thus would make data entry effective and unsophisticated. The constitutional features of a database will diminish the risk of errors during the input process. Adding a brisk record to a database would be simple as entering it underneath the previous record. Report can also be easily printed get through from a database and are aesthetically pleasing in appearance already without the need of major modification.Data ecesis is also a advert area of this project and a database al ready has the desirable data validation methods pre-set check embedded into the core of the database application.DisadvantagesFunctions much(prenominal) as the ability to carry out complex mathematical calculations are non necessarily allow in a database application. To smite this irregularity the database would stupefy to be cross-linked to a spreadsheet application. This would of course multiply the workload and the size of the task, which would be pointless. to a fault, other features of a database are fairly limited. This would therefore mean that the database constitution could not be adequately adapted to tackle the problem. This solution could put up to be expensive.commercial SoftwareAdvantagesCommercial Software curriculums are generally simple and rise compositors caseed to the problem at hand to some extent. They are well-situated to utilise and come with extensive help oneself guides to modify the functions and utilities to suit the and help the end user an d also include suitable training materials and tasks for IT illiteratesDisadvantagesThe cost of these Commercial Software programs are quite spicy. The features of these are not suitable for a task of this build and even with major modification would not be completely suitable and would be prone to error. Such programs do not have validation methods built-in and do not allot for addition of such Add-ons. This would be a stumbling block to the whole program and the quality of the program would suffer as a result. This solution could prove to be expensive.Spreadsheet SystemAdvantagesA spreadsheet System would be a more(prenominal) obvious solution. Such a spreadsheet would be able to be apply with alleviation. The outstanding feature of a spreadsheet over the other options is the ability to enter and manipulate complex mathematical formulae and the ability to process numerical determine without too much effort. All of the task could be completed indoors this one package without the need for integration with other programs and partial embedding surplus programs. This can be implemented by the fact that the sheets can be linked to each other. Reports can be easily printed out via the large feature of the spreadsheet.DisadvantagesTo be able to use the spreadsheet, the unwritten rules of manipulating formula within a spreadsheet have to be mastered. Exact placement of cells and macros would have to be recorded. The spreadsheet schema layout is fairly difficult to follow. This solution could prove to be expensive. betrothed ProgramAdvantagesThe advantages of creating a bespoke program apply a high level/imperative programming language is that the styles, functions and forms of the screens can be manipulated to suit the end users. The program would come with extensive help guides and instruction for the end users. The screens would de intentional specifically using extensive investigate techniques to gather reading for the program and to meet the users requirements and create a user-friendly interface. Behind this user-friendly interface, all of the required formulae and utilities could be implemented. The cost of creating a bespoke program is virtually none after purchasing the software to create such a program with its official license, which is a great advantage over the previous examples.DisadvantagesThe only obvious disadvantage to such a solution would be the time taken to complete the task. After the initial research and design period, the whole design and implementation of the program and extensive scrutiny could take 3-4 months to be fully implemented.Online Web-Based dissolventAdvantagesThe advantages of using on online system is that the system does not have to be limited to one mold or a local network of computers plainly this accessibility can be enlarged and accessed all over the world by the decently personnel. Security can be maintained my strenuous password and security checks and Internet I.P. addresses can be recorded and monitored. Integration of spreadsheets demand to be implemented into such a Web-Based Solution.DisadvantagesIf this solution were to be implemented, it would be a very foolish decision. The fact that it can be accessed all over the world maybe appealing at first, but what if the security of the website is overcome and the marks of hundreds if not thousands of students could be modified by a solitary teenager with a bit of effort. This would bring the whole judicature into disrepute and affect the future of many students. Apart from the security concerns of this solution, the fact that it needs to be linked to a spreadsheet so that calculations can be carried out successfully is an unpleasant feature to this exaggerated solution. Reports could be printed to an extent but the design would be very unprofessional if not amateurish as any user can do this. This solution could prove to be expensive.Paper-Based SystemAdvantagesThere are no real advantages of a paper-bas ed system apart from the fact that it is a method of recording the informationDisadvantagesThe disadvantages include the inability to save information in a professional manner. Sheets could be misplaced. Only one user can use the system at once. Handwriting can be a problem to read and understand. in any case mistakes can easily occur much to the despair of students.Chosen SolutionOne thing to realise is that no problem has a solution, which is atomic number 6% perfect. This is true for the problem at hand as well. As they all have some disadvantages it is the one, which has the most advantages and the least disadvantages. That seems obvious enough to me that is wherefore I have chosen to create own program using the BESPOKE PROGRAM option.The reasons why have chosen this option is because it is a sensible option and it can be suitably implemented and designed to the users requirements as it can be manipulated and shaped to perfection. Also it is not that pricey so it will keep the bank manager happy, which would not have been the case if I had gone with the other optionsThe layout of the forms could be suited to use the user and I would not have to add features, which are not required by the users. The feedback from the users can be employ to design the type of inputs and railroad sidings they require from the program and how they would like to enter the data and then output the information in the form of the reports. This also enables me to create a varied and innovative solution to the problem.The reasons why I have not used some of the other possible solutions is some of them are not pragmatical while others are surreal The idea of incorporating two programs to work unitedly with each other appears to be out of the question, as it would make intent hard for the end user then the current methods they are using. Also some of the solutions suggest features, which could affect the integrity of the data within the organisation and allow it to be prone to hacking and malicious damage from external sources. new(prenominal) solutions do not have the necessary features to carry out this task. This is why I have eliminated these solutions when considering which solution to use and the only one that seemed practical would be the BESPOKE PROGRAM option.
