QFD Matrix for Incremental Construction of a Warehouse via Data Martsue to the complexity of data stores, relationships, transformations, and the processing involved. In this paper we consider the problem of identifying the next data mart to construct and present a tool based on Quality Function Deployment for use in the planning stages.作者: LVAD360 時間: 2025-3-22 09:41 作者: 滑動 時間: 2025-3-22 13:16 作者: 滑動 時間: 2025-3-22 18:24 作者: Flat-Feet 時間: 2025-3-22 22:42

A Metamodeling Approach to Evolutionse. Within the domain of UML metamodeling, a refinement of the metamodel-level classification is proposed that includes bases for defining a metric of the evolution (in terms of distance between metamodels).作者: Semblance 時間: 2025-3-23 06:03
Advances in Science, Technology & Innovationly stable for the whole life-span of the object; the evolving behavior can be changed dynamically at runtime. In this paper, we present an extended specification framework for modeling evolving objects. Particularly, this framework provides the basis to explicitly specify behavior evolution.作者: 不合 時間: 2025-3-23 13:02
Reviving Sudan’s Ancient History and Tourismnal case study into the evolution of conceptual schemas. The main contribution of this paper is the realization that the measurement of conceptual schema stability is an essential step for understanding and improving current theories and best-practices for designing high-quality schemas that will stand the test of time.作者: FUSE 時間: 2025-3-23 16:21

Adaptive Specifications of Technical Information Systemsios are based on computer control, their software implementations also depend on previously established formal descriptions. Additionally, technical information systems such as production control facilities often have a long life span. Due to this fact, dynamic changes become increasingly likely.

Schema Evolution and Versioning: A Logical and Computational Characterisationwe present the formalisation of a general model for an object base with evolving schemata and define the semantics of the provided schema change operations. We will then sketch how the encoding of such a framework in a suitable Description Logic will allow the introduction and solution of interestin作者: 痛恨 時間: 2025-3-25 04:15 作者: AMITY 時間: 2025-3-25 09:09 作者: corpuscle 時間: 2025-3-25 12:32 作者: OCTO 時間: 2025-3-25 18:36 作者: START 時間: 2025-3-25 21:30 作者: prick-test 時間: 2025-3-26 03:38
Extending the Object Query Language for Transparent Metadata Accessed extensive queries over both application data as well as metadata. However queries over metadata via OQL, a de-facto standard for object query languages defined for the ODMG 2.0 Object Model, are tied to low-level implementation details of the underlying schema repository of the database system.

Schema Evolution in SQL-99 and Commercial (Object-)Relational DBMSA . denotes the description of the structure and behavior of a database. Straightforwardly, (database) . refers to changes of the database schema that occur during the lifetime of the corresponding database. It particularly refers to changes of schema elements already stored in the database.作者: Mendacious 時間: 2025-3-27 00:30 作者: ACTIN 時間: 2025-3-27 03:40 作者: 打包 時間: 2025-3-27 06:17

Under the current tightly-coupled database architecture, updating the object model is an extremely expensive undertaking for a database vendor both in terms of time and resources.

Conservation in Highly Fragmented Landscapesimple and semantically clean solution to the problem of schema mismatches that arise when the schema of a database is changed and some data no longer fits the schema.

For a more flexible consistency management we enrich this first proposal by an adequate meta-level, where constraints may be dynamically created, modified or deleted. Finally, we show how this proposal covers a large number of constraint sub
