Object-oriented database systems: How much SQL do they understand?,cepts of query languages, and analyse the query facilities of the systems. The analysis leads to a classification of query languages, precisely differentiating the capabilities. Further aspects concern the embedding and the style of query formulation. The comparison is based upon empirical evaluatio

On the optimal top-down evaluation of recursive queries,rmation” , we try to eliminate many of the expansion operations that have to be done by any other top-down strategy. Further, we speed up the evaluation for cyclic data by generating most answers to a query directly from the intermediate results and the relevant path information instead of evalu

A generalized semantic model for CSCW systems,based on both theoretical foundations as well as empiric principles. A three level model is proposed, a high level interaction model, a detailed elaboration of model constructs and behaviour based on state transitions.
