Visualizing information across multidimensional post-genomic structured and textual databases

MOTIVATION Visualizing relationships among biological information to facilitate understanding is crucial to biological research during the post-genomic era. Although different systems have been developed to view gene-phenotype relationships for specific databases, very few have been designed specifically as a general flexible tool for visualizing multidimensional genotypic and phenotypic inform...

Incomplete Information in Relational Temporal Databases

For the conventional relational model there has been considerable research in the area of incomplete information. On the other hand, research in temporal databases has concentrated on models in which complete historical information is needed. However, the likelihood of missing information in temporal databases is greater because of the vast amount of information. Hence, a mechanism must be prov...

Comparison of Bibliographic Databases in Retrieving Information on Telemedicine

Background & Aims: Some of the main questions which can be of importance for those researchers who intend to perform a systematic review in a field of science are: ‘What databases should I use for my review?’; ‘Do all these databases have the same value?’; and ‘Which sourcesretrieved the highest of relevant references?’. The main aim of this work was the identification of the best database for ...

Issues in Visualizing Large Databases

In this paper, we describe our concepts to visualize very large amounts of data. Our visualization techniques which have been developed to support querying large scientific databases are designed to visualize as many data items as possible on current display devices. Even if we are able to use each pixel of the display device to visualize one data value, the number of data items that can be vis...

Using lattice-structured domains to represent imperfect information in databases

The relational model, as proposed by Codd, contained the concept of relations as tables composed of tuples of single valued attributes taken from a domain. In most of the early literature this domain was assumed to consist of elementary items such as simple (atomic) values, de ned complex data types or arbitrary length binary objects. Subsequently the nested relational or nonrst normal form mod...
