Expertiza is a web application where students can submit and peer-review learning objects (articles, code, web sites, etc). It is used in select courses at NC State and by professors at several other colleges and universities.<ref>Expertiza on GitHub</ref>
Project Description
Currently when an Instructor logs into Expertiza,there a lot of select* from assignments queries being fired on database which would have an adverse effect on performance. We analyzed the source of this issue and made some changes, which reduced the number of select queries executed. The performance is high improved. The mission involved is tracing the source of the issue and modify the code to fix the issue.
