Data Modeling Tool: SILVERRUN RDM Relational Data Modeler (Relational Data Modeller) supports logical and physical design of the business architecture on ecosystem, enterprise, application and database level.
Critical to the design of an historical database model is the representation of the Sexistence?of objects across the temporal dimension -- for exampleClifford, JamesCroker, AlbertJ. Clifford and, A. Croker, "The Historical Relational Data Model (HRDM) and Algebra Based on Lifespans", in ...
The operation of RDM depends on the distributed database software which performs decentralized control of the database using Codd's relational data model (CACM, 13(6), June 1970). First, the role of distributed processing in the evolution of database machines is presented. Then several sections...
1.This paper puts forward a new temporal relation data model, expounds concept of time filtration and relation algebra operation of temporal data based on the model, and provides illustrations.提出一种新的时态关系数据模型C TRDM和基于该模型的时间过滤操作,并结合时态数据关系代数运算实例,说明它是完备...
1.The Study of Rough Data Querying Based on RRDB;粗糙关系数据库的粗糙数据查询研究 2.Based on RRDM(Rough Relational Database Model), a querying theory of RRDB (Rough Relational Database) is analyzed through decomposition principle, projection principle, definability of RRDB and lower approximation ...
The Relationship Dissolution Model (RDM) was used to analyze what and why virtual possessions people retain or delete after a romantic relationship breakup. Participants ( N =406) completed online open-ended survey questions to understand their decision-making process for retaining or deleting relations...

This research paper presents related relational research works to multi-media(MM) data, systems, data bases, and data base management systems. It gives an up-to-date survey of relational research works using the existing capabilities of the Relational Data Model(RDM), as well as extending the ...
The relational database model (RDM), proposed by Codd, has been proven to be a very useful model in many applications. The inherent of the RDM is effective for precise and unambiguous data. However, real world applications often include imprecise and uncertain information. Therefore, Beaubouef ...
