The equivalence problem for relational database schemes,e set of dependencies allowed for defining schemes deal here as parameters. A comparison of the equivalences shows that there is only one natural kind of equivalence. For various cases we prove its decidability or undecidability. Besides we get a characterization of mappings expressible in the relat作者: 案發(fā)地點(diǎn) 時(shí)間: 2025-3-24 19:43 作者: Campaign 時(shí)間: 2025-3-25 02:01 作者: 無畏 時(shí)間: 2025-3-25 06:11
Designing alpha-acyclic BCNF-database schemes, First, it is shown by a sample relation scheme, that these three properties are not always obtainable. This result is independent of any design method. Secondly, the problem of using the BCNF-decomposition algorithm for designing database schemes, which are additionally α-acyclic, is investigated. 作者: propose 時(shí)間: 2025-3-25 09:10

Modal logic and incomplete information,Our purpose is to use modal logic for incomplete information processing..So we study some systems - K1 and IDB -, more adapted to our task than S4, but with a very strong use of CWA..Then we propose a more flexible approach: the "multiverse" approach, which gives, to our opinion, a good formalism for incomplete information.作者: 說笑 時(shí)間: 2025-3-25 18:45
