Correcting User Errors in SQL
International Journal of Man-Machine Studies
Previous human factors research on SQL has discovered many correctable errors made by users. An experiment was run, testing how seriously error correction would affect SQL user performance. In the study, 39 subjects used SQL without error correction and 40 subjects had specific categories of errors corrected. The main result was that error correction improved user performance by 26%.
