It focuses on database learning activity in general education. By using saccess, students can study the basic concepts of relational operations of some tables, such as projection, selection, and join. Students can see the source table and result table of the operation. In this paper we will show the requirements of tools for database education in general education, explain the design and implementation of saccess and discuss the advantage of saccess through the experiments. Keywords: database education, general education in computer science, relational database, online tool for education 1. saccess POS 1 Okayama University, Okayama , Japan 2 Kobe High School of Science and Technology, Kobe, Hyogo , Japan 3 Osaka Electro-Communication University, Neyagawa, Osaka , Japan 4 Neyagawa High School, Neyagawa, Osaka , Japan a) b) c) d) [1] [2] saccess saccess 5 c 2014 Information Processing Society of Japan 2
