This system was constructed to offer pig farms the opportunity to manage the data coming from hog marketing. Through the records of the trade market and the slaughter and sale of pork, the manager of the pig farm could therefore better understand the procedures of hog marketing and the sale of pork. This system was developed by Microsoft VB.NET 2005 programming language connected with Microsoft Office Access databases. The system was divided into three parts in terms of code set up, data maintenance with report and statistical analysis. The items of data maintenance are concerned with pig transportation, the hog market, slaughter, carcass cutting, storage and sales. The manager of the pig farm could thus utilize data at different periods to perform statistical analysis to reflect immediate selling information from market and obtain the optimal trade market and sale income.
