Introduction

Design Consideration for possible solutions Comparison of alternative solutions This project could have been implemented in a number of different ways, for example either a database or spreadsheet package could be used, or the current paper based system could be streamlined for a more efficient data management. However, I have decided to use a spreadsheet package above the rest as it contain certain advantages which are very useful within the context of a stocking system for a restaurant. It is far better than a paper based system due to the automation available in a computerised system. This would mean that there would be a lot less mistakes when totalling up invoices and purchase order requisitions. The spreadsheet system also speed up the whole process from hours of paper work to jus a few clicks of a button, and the computerised system will not forget anything, so what needs to be done, will be done, unless the user decided to leave it out.

So a reliable computer system is required for the smooth running of Access. Excel, less demanding on a system than Access, will still prove to be unstable on extremely slow machines. A paper base system will never crash, however are susceptible to coffee stains, crumpling, ad being eaten by the dog 4 Again with the aid of the user forms, and the manual, the process should not take much time. The process should take even less time in Excel as each cell can have a note attached to it, to act as a reminder to the user of what to do. The user mush hand produce all tasks, so will consume large quantities of time 5 Access is by far the most expensive piece of software, with the latest editions reaching into the hundreds of pounds, then plus the new computer system Excel, although cheaper than Access is still expensive, costing approximately �50. ...read more.
