DESIGN AND IMPLEMENTATION OF A COMPUTERIZED MARKET SURVEY REPORTING SYSTEM
CHAPTER ONE
1.0 INTRODUCTION
In order not to embrace hitch in the carrying out of any project, it is necessary to define the objective of the project. The process surveying enable us to map out the limitation and the delimitation of the project.In surveying, we set out the necessary steps and areas that considered to be useful and necessary to implement the objective. In this case, we identify the problem, it’s sources, causes and to identify solutions to the problem. In the case study of doing these, the objective must be certain.
- BACKGROUND OF THE STUDY
The Background of this study involves in-depth study of the system report of computerized market survey being designed to determine the input data to the report system and how system report objective can be realized.
Data collected or survey made determined the system output and input and grouped into various files (1) Equipment requirement.
EQUIPMENT REQUIREMENT: To use this report system in survey the following equipment may be needed.
- An IBM or its compatible
- Magnetic Diskette (3.25 x 5.25 or 35 x 3.5 inches)
- An IBM line printer or its compatible
- A printer interface cable.
Optional equipment: Hard Disk Properly Installed.
MEMORY REQUIREMENT: The design of this system was highly structured by breaking the program in module using Top-Down design technique and loding the program in GW BASIC. Each program after use call another program from the diskette and pass over the content of relevant variable over to the incoming program by using “COMMON” statement it minimizes effectively the size of primary memory required by the system.
TEST DATA
The whole system was tested by obtaining survey analysis of previous building project. Fed the cost of sub-element into the system and compare the output.
DOCUMENTATION
This system is documented in a way that any one who is not a computer scientist or market surveyor can use it effectively. The following types of a documentation are implemented.
- Design documentation
- Operational documentation
- Test documentation OBJECTIVE OF THE PROJECT AIM
Market survey report system has the following objectives
(i) To give client good value for money
(ii) To achieve the required balance of expenditure between the various parts of the building
(ii) To keep expenditure within the amount allowed by the client.
STATEMENT OF THE PROBLEM OR PURPOSE
Recent Researchers to a great extent have been directed towards finding means of efficiency, accuracy and speed of doing work and at the same time reducing man-hou. Required for each piece of work. The success of these Researchers have been attributed to the invention of modern computers.
But all these recent invention and discoveries not withstanding, the work of the market surveyor has largely remained a manual work. Hence the research problem is to explore the possibility of the market surveyor in Nigeria employing the technology of our days (computer) in the daily discharge of his duties. The use of computer in cost planning has the following advantages over the manual process.
SPEED – Computer are very fast in carrying out operations as compared to humans. E.g the production of survey plan may take five to 10 man – days. But with computers, it is a matter of seconds. This reduces the time of the market surveyor will spend on each job.
ACCURACY: Once the data have been entered correctly into the computer the need for further manipulation by means of humans is eliminated and possible errors reduced. Also when properly programmed, computers are unlikely to make computational errors.
1.4 JUSTIFICATION OF THE PROJECT TOPIC
It is justified that ever before the introduction of computers in survey system report process, there was no accurate and complete similar work related to such. Therefore, we advice that in the course of this research work if necessary any suggestions would be welcome.
