Balanced centralized and distributed database design in a clinical research environment.
Clinical research databases can meet both research and clinical needs, but this ideal is seldom achieved. Priorities often differ for those who collect and ultimately use the data and those who develop data systems. Traditional database designs also create logistical barriers that hamper communication. The Michigan Alzheimer's Disease Research Center has developed a secure, distributed data sys...
متن کاملVirtual Database Technology for Distributed Database in Ubiquitous Computing Environment
In this paper, our research objective is to develop a database virtualizat ion technique in order to let data analysts or other users who apply data mining methods to their jobs use all ubiquitous databases on the Internet as if they were recognized as a single database, thereby helping to reduce their workloads such as data collection from the Internet databases and data cleansing works. In th...
متن کاملVOXMEX Speech Database: Design of a Phonetically Balanced Corpus
We present a method for designing a phonetically balanced speech corpus. In this method, we used a phonotactic approach to design the phonetic content of VOXMEX: a phonetically balanced corpus for Mexican Spanish. The transcriptions of VOXMEX contain a complete coverage of phonemes and allophones of Mexican Spanish in every possible context. This corpus is designed for doing phonetic research a...
متن کاملA Comparison of Distributed Database Design Models
Although numerous database design models and solution algorithms have been developed, there has been little work that compares and evaluates these models. Lack of such work has left u s with several questions: Do the more comprehensive models actually result in better solutions than the simpler models? If so, what makes them better? Are they better under all conditions or only under certain con...
متن کاملDistributed Database Design – Top-Down Design
The design of distributed databases is an optimization problem requiring solutions to several interrelated problems: data fragmentation, allocation, and local optimization. Each problem can be solved with several different approaches thereby making the distributed database design a very difficult
