Abstract:
The objective of this study is to develop the computer program used for collecting and storing data on database system in a petrochemical plant case study It has been found that the storage system is not working property since the system stores the document causing the delay in searching and the inaccuracy in controlling the references. The information technology department receives a computer delivery notification from a vendor in hard copy of fax format used as an evidence of delivering good to customers. The improvement is to design the new database system to store data more effectively on personal computer. Results indicate that the new database system use less time for processing the information. They spend only 45 minutes to complete the task, saving up to 47 hours and 15 minutes as compared to spending 2 days in case of using the previous database system. In addition, the accuracy of getting the right information increases up to 95%. More importantly, this improvement can avoid over 1,168,000.00 THB for the work delay penalty
