Software: I have decided to use windows 2000 over windows 1998 because it is capable of running more tasks more efficiency as compared to Win. 98 that runs 16-bit and 32 bit. It has more security, stability, NTFS, and FAT16/32. I have also decided to use: Spreadsheet Modelling - for producing invoices and cost plans. Can be used to create models, simulations or expert systems for others to use. Examples: Microsoft Excel, Lotus 1-2-3. Facilities include: entry of …showed first 75 words of 3222 total…

…showed last 75 words of 3222 total…nd compares the form and what has been entered onto the system. Re typing- After the user has typed in the information another member of staff should come and type in the information, the data will only be processed if both entries are identical. It is unlikely that both people will make the same mistakes. The Re-typing method is expensive and time consuming but proof reading will be effective and easy to put into practice.
