Semantic relativism in conceptual modeling,85], ), ) as a basic modeling construct is used. The presented results show how to deal exactly with so called semantic relativism, i.e how to express that two different semantic database models have the same expressive power. We show that it is easy to reach the property for many of well-known semantic database models.GRE 发表于 2025-3-26 00:29:53
,Information handling — A challenge for databases and expert systems,techniques to embed expert system functionality into each single step of the process of information handling. An integrated prototype, which is currently under development at GMD-IPSI, will be outlined at the end of this paper.血统 发表于 2025-3-26 07:48:53
Predict query processing cost in a distributed database system,different configurations based on experiments on a very limited number of configurations. Our experimental results indicate that the proposed methodology fairly accurately predicts the performances of new configurations.耐寒 发表于 2025-3-26 11:59:52
On temporal-fuzziness in temporal Fuzzy databases, can provide upper bounded, lower bounded, and approximate answers to queries. Then, the Temporal Fuzzy Data Model and a metadatabase are proposed. The concept of metadatabase allows the time-variant property of fuzzy meanings to be modeled. Since based on the relational model, our model has a unifo细胞学 发表于 2025-3-26 13:14:57
