Defining the usability of query performance : an experimental approach / Aida Zuliana Abdul Wahab

Prior research on human ability to write database queries has concentrated on the
characteristics of query interfaces and the complexity of the query tasks. This paper
reports the results of a laboratory experiment that investigated the relationship between
user characteristics and query types on performance by using Ms Access and MySQL
database systems. This relationship is not investigated in earlier database research, while
controlling the query interface, data model, technology, and training. By using two types
of database systems in this research which is Ms Access and MySQL, is important to
compare which database system is easier, comfortable to use and meet the project
requirements of the users. This report also discuss about the effect of database query
types on task performance. Finally, task complexity was found to be the main
determinant of user confidence. The implications of this result for future research and
practice are discussed.
