Before revision:  Based on our study, we make a number of observations and analyze their implications on the designof ORM frameworks and databases. Furthermore, we discuss new research topics in data management and software engineering that our study raises, and how OMAS can help in implementing them.
After revision:  Based on our study, we make a number of issues that lead to sub-optimal application performance, ranging from issuing queries, how result sets are used, and physical design. We suggest possible remedies for each issue, and highlight new research opportunities that arise from them.
