Database system is a collection of information that can be easily accessed managed and updated. With the rapid expansion of the Internet database overload is increasing rapidly. Large amount of data complexity of information and needs for quick responses had caused critical problems of database access. One of the techniques to optimize effectiveness of query is to use SQL tuning. The improved SQL could speed up database access and save the resources of computer. This article introduces a tool called ‘execution plan for SQL tuning’. In addition an example is also provided to check the processing of SQL command.

This research aims to develop a web-based instruction (WBI) applied in the computer technology course. The proposed WBI composed of the following components: lessons of the computer technology course pre-test and post-test exam: determining the effectiveness of the proposed work and user satisfaction questionnaires. It is also evaluated a study achievement and a usage satisfaction by using efficiency and effectiveness test of lessons and satisfaction test of users. In this work users are the second year students in major of Computer Technology Faculty of Science and Technology Rajamangala University of Technology PhraNakhon for 30 students. For experiments the results show that its efficiency is 80.13/83.67 which are met the standard criterion 80/80. In addition the study achievement scores of students who studied the proposed WBI are also higher than students who studied with ordinary courses at the statistical significant level 0.05. Furthermore an average of students’ satisfactions score is 4.20 which determines students satisfy with the proposed WBI at a high-level. Finally it can be concluded that the proposed WBI is effective.
