Formatted abstract Using information systems to answer inherently complex questions requires formulating difficult queries, which sometimes cause users to make syntactic and semantic errors. The level of normalization of the data structure may increase the complexity of some queries and cause users to make even more syntax and semantic errors. This research investigates the effect of different levels of task complexity and normalization on syntactic and semantic errors. The results showed that users querying data structures normalized to the first normal form made significantly fewer errors of both types than users querying unnormalized data structures. Users of first normal form data structures also made fewer errors of both types than users of the third normal form data structures, however, the results were not statistically significant.
