Students said the course gave them a good understanding of database skil s and SQL. However, the course was very disorganized. The professor was often late and due dates were unclear. Students suggested the course would be improved by better organization, consistent due dates, and getting assignments back faster. Overall, students said the course teaches you about databases, but tends to be disorganized and takes a lot of work.

Students believed that the best aspects of this course included learning languages like QBE and SQL. They believed that the things they learned would be useful in real world situations and that they understood how to manipulate databases. Students disliked how long it took to get feedback on their work and believed that the workload was excessive. They also found that the lectures lacked depth and were tedious. Students suggested assigning smal er, more frequent homework assignments that could quickly be returned with feedback. Students also wanted more engagement in the lectures, such as class discussions or multimedia. Prospective students should be prepared for a chal enging and work-intensive course. They should know programming and be prepared to learn additional languages.

Students thought the best aspect of the class was the practical usefulness of the material taught in the class. Students thought that their least favorite aspect of the class was the lectures which they thought could have been more interactive. Students thought the course could have been improved by providing a larger number of smaller assignments that covered a larger variety of the topics taught in the class. Students thought it was useful for students thinking about enrol ing in this class that there was little reading to do for the class.
