Data Security Of The New System

Extracts from this document...

Introduction

Data Security Of The New System The system I am designing will be storing a lot of personal details on customers, therefore it is vital that it is a secure system. To make sure that it is safe and secure I will be restricting access by placing a password on the system. It will also do checks to make sure that no invoices can be produced that contain invalid data. The formulae's used for calculations will be protected against accidental deletion to ensure the accuracy of processing and calculations. I have also recommended that a virus protection software is to be installed on the same computer that this software will be running from and that the user makes sure that the system is backed up frequently to prevent the loss of data. Implementation There will be one workbook called Byford's Organics. This workbook will consist of three worksheets, these being Welcome, Navigation page, Invoice and Mailing List. I have attached the layout design for these sheets along with a detailed description of the functionality of each sheets, a description of each macro code, security and validation details. ...read more.

From the Navigation page you can select to either go to Invoices or the Mailing List. Both of these pages will allow you to return the main navigation page. Justification Of The Choice Of Hardware/Software Used Below reveals the system requirements that are recommended to use: * Processor-233 MHz or higher * Operating System-Windows XP/Windows 2000 or later * Memory-128MB RAM * Disk Drive-CD ROM Drive * Pointing Devise-Microsoft Mouse Below are the properties of the computer I have been using to design the system. College Computer: - * Processor-2 GHz * Operating System-Windows XP * Memory-400MB * Disk Drive-CD ROM Drive * Pointing Device-Microsoft Mouse * Other-USB ports (portable backup of project, transporting from home and college). Justification Of The Choice Of Software Used I have chosen to construct the system on a spreadsheet as it offers a wide range of techniques to ensure that the input of data is sensible and secure. Simple mathematical functions are offered, with quick and efficient calculations. The type up was done using a word processing program as it offers me the necessary tools such as image cropping, spell check etc. ...read more.

Conclusion

To create this page I had to do several things. Firstly I had to copy and past the company logo. I then had to write the address underneath to keep the system looking professional and personal. After I done this I had to create a button which will allow you to access the next page. I did this by using the autoshape tool bar. Lastly I had to record a macro so that once the button is clicked you are navigated to the 'navpage' from which you can choose where to go on the system. I did this by right clicking on the button and selecting assign macro, I then entered the name of the macro 'navpage'. This then allowed me to start recording the macro. To do this part I had to click on the button and then select the sheet I wanted the button to navigate to. In this case the 'navpage'. Once I selected the sheet I then pressed stop to stop the recording of the macro. Macros The only macro placed on to this page will be for the button title "Click here to Enter". This macro button is to be named "navpage". ...read more.
