An Experimental Study of Object-Oriented Query Language and Relational Query Language for Novice Users

This study compares object-oriented query language (OQL) and relational query language (SQL) for novice users. The comparison focuses on the effects of different query languages on user performance for query writing task and query reading task in terms of time, confidence and accuracy. To accomplish this objective, a laboratory experiment was conducted. The results indicate that OQL subjects performed significantly better than SQL subjects for query writing in terms of time and accuracy and for query reading in terms of time, confidence and accuracy.
