- W90408768 abstract "End user computing (EUC) has become an essential component of successful knowledge management. To maintain their competitive advantage, organisations need to ensure that EUC is productive. Consequently, the problems encountered by end users in composing queries need to be minimised. In constructing queries, end users need to identify the columns, constraints, and aggregation level. They must then accurately translate these requirements into the appropriate constructs in the query language. The accurate translation of each requirement poses a challenge to end users due to the ontological gap between the representation of concepts in the real world and constructs available in the information system. This research examines the factors that influence end user performance in addressing SQL challenges. Ontology and cognitive psychology literature relating to memory schemas and semantic cues provide the theoretical basis for this research. A laboratory experiment was conducted with sixty-six students enrolled in introductory database subjects. The results demonstrate that end user familiarity with a particular SQL challenge has a positive relationship with query performance. The presence of semantic cues in the information request also has a substantial impact on query performance. These results provide assistance relative to improving end user training and designing query interfaces. Making these improvements will enhance both the efficiency and effectiveness of EUC." @default.
