Introduction

Evaluation In my evaluation, I am going to evaluate my all objectives (General, Qualitative and Quantitative objectives) as I have done in my design stage of Specification for the new system. I will describe how I have met all this objectives and after that, I am going to tell about some limitations and improvements for the new system. All Objectives: a. The system must be computerized. I have met this objective by creating the system by using relational database system rather than manual based system. As I have used different features of the database such as tables, report, queries, etc. this shows that the system is more computerised. b. The system should have password to protect it. I have met this objective by using a security password. It controls unauthorised access into the system without the password. Although, the system is protected by a password, all forms do not have password to protect it. ...read more.

Also it can able to make changes or correct the records of the customer by using the macros. d. Data entry should be quick. I have met this objective. As I have created 3 forms i.e. customers form, product form and order details form. it will be quicker for the end user to enter the data on the system through the form and I have created and added macro on all the forms so it will makes more easier and faster for the end user to enter data quicker. f.

Conclusion

I have met this objective. This system will able to create updated invoice of each customer whatever they have purchased so far and their past history of purchased in less than 30 seconds. Limitation of the database: When I go through my database then I found out limitations of the new system, a. In this database, customer will not able to buy 2 different products at the same time so they need to buy each one at different time. This may be limitation which takes longer time both for seller and customers while purchasing 2 different types of products. b. I don't have password for each form.. c. Limited validation checks- as my system couldn't ensure correct validation for 'E-mail' field. d. Less use of macros Future development for the system If I could have little more knowledge on database, I would have made the following improvements in my system. * More use of macros * More validation checks for 'E-mail', etc * Password protected on every form. * More command buttons to make my system more users friendly. ...read more.
