Consistency Enforcement in Databases,termined. The approach turns out to be well-founded since the GCS for such complex programs is effectively computable if we require loops to be bounded..Despite its theoretical merits the GCS approach is still too coarse. This leads to the problem of modifying the chosen specialization order and to 作者: biosphere 時間: 2025-3-22 03:33 作者: 推測 時間: 2025-3-22 06:08 作者: atrophy 時間: 2025-3-22 08:45 作者: HEED 時間: 2025-3-22 16:55

The particular approach used throughout is to consider ILC design in the iteration domain, rather than in the time domain. U作者: 我正派 時間: 2025-3-23 02:55 作者: STRIA 時間: 2025-3-23 09:21

Semantics in Databases,e. In computer linguistics or web research, semantics is a component of the language which associates words or components of a grammar with their meaning (linguistic content). In modeling and specification, semantics assigns set-theoretic denotations to formulas in order to characterize truth.

Characterization of Type Hierarchies with Open Specification,ork, such incomplete hierarchies are viewed as .; that is, descriptions which are sets of constraints. The actual hierarchy is then any structure satisfying these constraints. For such specifications, two forms of characterization are provided.

Semantic Classifications of Queries to Relational Databases,aic (hence, semantic) characterizations of equality of theories for databases, in . and in weaker logics. We introduce an abstract notion of . for databases, as equality in the theories for a given logic and we define different sub-classes of queries by requiring that the queries in a given sub-clas作者: 含糊其辭 時間: 2025-3-25 09:41

Characterizing and Computing Semantically Correct Answers from Databases with Annotated Logic and Aorder queries. Both the annotated logic and the logic programming approaches work for any set of universal and referential integrity constraints. Optimizations of the logic programs are also analyzed.作者: 不可知論 時間: 2025-3-25 17:58 作者: Flatus 時間: 2025-3-25 23:54 作者: Conflict 時間: 2025-3-26 04:03 作者: 比喻好 時間: 2025-3-26 07:07
Null Values in Relational Databases and Sure Information Answers, world semantics. The focus is on the . and the . interpretation of null values. A new semantics for the . interpretation of nulls is proposed taking into account a problem arising in connection with the closed world assumption.

Reasoning with . . is very efficient, and it can be used for performance reasons before . . is evaluated.
