1.1

Introduction In the world of developing the information technology, most of people in Myanmar

are changing to use computerized system instead of manual system. Our project title is “Point of Sale System of construction material shop”. By using our software, users can analyze sales records, and figure out how well all the items in the shop sell. Also, they can maintain and review sales histories easily. We used Microsoft Visual Basic 2010 and Microsoft Access Database.

1.2

Objectives  To enhance the manual system to computerized system.  To service quickly and efficiently.  To reduce human work power and uses of paper.  To review sales histories easily and quickly at anytime without losing data records.

1.3

Current system problem In the current manual system, sales records, customer’s information and import histories are recorded and stored by using papers and files. So, it has many problems such as duplicating data, leaving off data in recording and calculation errors. As the manual system uses paper and files, they are unable to search or review such records of files easily and quickly. Also, there may be lost of data records. 6

1.4

Proposed system In the proposed system, we will able to:  Reduce unnecessary paper works.  Speed-up searching the data records.  Reduce errors and time.  Let the users know in hand stocks and buying prices within a short time.  Give essential reports to manager in time.

1.5

Feasibility

1.5.1 Economic feasibility As we are changing to the computerized system, we must consider about the commercial benefits and operational costs. So, the expense of developing the system should be less cost. We can also get intangible benefits. For example, we get the customer’s satisfaction for comfortable, quick and good customer services.

1.5.2 Operational Feasibility When changing to the computerized system, most of the staffs are not well trained in computers. So, we must provide paper training, explanation and user manual to understand and able to use the computerized system efficiently. This can make the staffs and manager more qualify and increase the standards of the work. 7

1.5.3 Technical Feasibility Our computerized system is easy to use for some staffs and managers who have experience and are expert. But we should train the staffs who can only work manually. In the manual system, duplicate data can’t be searched easily, but it can be easily found the desired information in our new system.
