Creating a computer system essay

Again there are no financial resources as users are not willing to pay for the package. As I have decided to use spreadsheets or databases to design the system I will compare both packages in order to decide which package to use.

Comparing a database package and an excel package When I compare the packages I will compare Excel and Access because these are the two packages, which are available at home and at the company shop. Here are some areas to test each application: After looking at both of them I have decided to use Microsoft Excel This is because Excel enables designers to create specifying error messages.

It is generally a better application to use, to create and invoicing system, as access is more of a database package, for storing and searching through customers. On my system the users will not be searching through customers on the computer, as they will have hard copies of invoices, for them to read.

Excel allows you to use formulas to work out complex sums automatically. There is security and passwords to limit access to the system. Excel allows you to create forms and menus, to create a user-friendly system. Excel allows the user to use macros to shorten long tasks, for example copying and pasting cells to another sheet.

Although access is ideal for creating queries to search through the system, and making reports, this will not be needed in my system. My system will depend on the invoice sheet and balance sheet, rather than reports and queries. Unlike access, excel allows users to create charts and graphs.

I will have a separate worksheet with a macros button, allowing the user to look at their graphs of profits and losses.

In my system I will be using many formulas in the worksheets.

I will need formulas to work out the sub total, VAT and total in the invoice sheet. The computer should automatically work out the totals, when the customer has entered the purchases, and the totals should appear in the cells.

I will also need macros to save the work sheets or return to the main menu. Other macros are described in the inputs, outputs and processes. This will be a major part of my system, and will be used on nearly every worksheet.

On the invoice sheet for example, there will be a form to enter customer purchases, enter the customer details, and enter the customer ID or a form for the main menu. In the stocks worksheet there will be a form to enter a new product. Every worksheet will have a form, which will take them back to the main menu.

From here the will be able to move to another sheet. In excel I will be able to add security to the system, and I will be able to protect certain worksheets. I can also add user names and passwords, and control access levels, so certain members of the staff have access to certain worksheets.

This will be a good feature of excel to use in my system, as I can use auto filters to sort the customers or invoice lists. For example, the user may want to target their advertising to the customers in a particular area such as slough. To do this they could use an auto filter function, which would come up with all the customers who live or work in slough.

Overview of the System The system will be based on one workbook, containing a number of worksheets. The main worksheet is the invoice sheet, which allows users to add customer details, and to choose their products.

Once they have finished they can save and print the invoice, and their details will be added to the customers worksheet, and the invoice lists sheet. Then they can either exit the menu, or go to the main menu and click on another worksheet.

The other worksheets in the system is the balance sheets, which shows company profits and losses, and the worksheet which allows the user to create charts based on the profit and losses figures from the balance sheet.

There is also a stocks worksheet, which allow users to edit stock levels, add and delete products. The other two worksheets will contain details of all the customers, and all invoices, which have been created.

Each year, the users can create a new balance sheet, and chart to show the profits and losses. Each time the user starts using the system, there will be a comment to welcome them, and then the main menu will appear. This will allow them to go to the worksheet that they require.My guess is that the question is regarding a general Operating System that can be used by just about anyone as it is for personal or professional use.
