Research on the differing computer abilities of men and women has shown that women have fewer computer skills than do men, and women in general lack interest in computers compared to men, verifying the stereotype. However, the popularity of new computer technologies and the widespread use of the Internet have significantly influenced the differences in computer ability between men and women. This study focuses on the influence of gender for database self-efficacy and identity for I.M. departments and their influence on academic performance. This study collected 123 samples from master and undergraduate students. The findings showed that: (1) there are no significant differences regarding gender in database self-efficacy and identity in I.M. departments, and (2) students who have higher database self-efficacy have higher academic performance.
