1. DDAN: A distributed directory for ambient networks / DDAN: A distributed directory for ambient networks
Ambient Networks (AN) were designed with the goal of establishing the interoperability between different types of networks. This interoperability aims to attend the services requested by users, independently of their current location, type of network and access technology. The Project is motivated by futuristic scenarios which make the technology more and mo

2. Managing the lifecycle of sensor data : from production to consumption / Gerenciamento do ciclo de vida de dados de sensores : da produção ao consumo
Sensing devices are becoming widely disseminated, being applied in several domains, noticeably in scientific research. However, the increase in their number and variety introduces problems on managing the produced data, such as how to provide sensor data at distinct rates or temporal resolutions for different applications, or how to pre-process or format the

3. Integração de fontes de dados heterogeneas baseadas no modelo de dados XML
Over the last few years, the Web (World Wide Web) has been used to publish databases, however the user must consider the features of such environment before to establish the database integration. This work proposes using the MDBS (Multidatabase System) architecture to integrate heterogeneous databases in flexible and dynamic environment, such as Web or ad ho

5. Managing the evolution of XML-based mediation queries
In recent years, the problem of integrating data from heterogeneous and autonomous data sources has received a great deal of attention from the database community research. This problem consists in providing a uniform view of these data sources (called mediation schema or global schema) and defining a set of queries which compute each object in the mediation

6. Uma metodologia para integração de sistemas legados e bancos de dados heterogeneos
Applications increasingly need to access different data sources to get information. Many of these sources are managed by legacy systems, and need to be integrated or migrated to become more flexible and manageable. This work proposes a methodology to help the integration of these heterogeneous data sources and which takes legacy data into account, considerin

7. Galaxy: A platform for interactive large-scale genome analysis
Accessing and analyzing the exponentially expanding genomic sequence and functional data pose a challenge for biomedical researchers. Here we describe an interactive system, Galaxy, that combines the power of existing genome annotation databases with a simple Web portal to enable users to search remote resources, combine data from independent queries, and vi

8. The UCSC Table Browser data retrieval tool
The University of California Santa Cruz (UCSC) Table Browser (http://genome.ucsc.edu/cgi-bin/hgText) provides text-based access to a large collection of genome assemblies and annotation data stored in the Genome Browser Database. A flexible alternative to the graphical-based Genome Browser, this tool offers an enhanced level of query support that includes re

9. EnsMart: A Generic System for Fast and Flexible Access to Biological Data
The EnsMart system (www.ensembl.org/EnsMart) provides a generic data warehousing solution for fast and flexible querying of large biological data sets and integration with third-party data and tools. The system consists of a query-optimized database and interactive, user-friendly interfaces. EnsMart has been applied to Ensembl, where it extends its genomic b

10. Generic data modeling for clinical repositories.
OBJECTIVE: To construct a large-scale clinical repository that accurately captures a detailed understanding of the data vital to the process of health care and that provides highly efficient access to patient information for the users of a clinical information system. DESIGN: Conventional approaches to data modeling encourage the development of a highly spec

11. Pseudomonas aeruginosa Genome Database and PseudoCAP: facilitating community-based, continually updated, genome annotation
Using the Pseudomonas aeruginosa Genome Project as a test case, we have developed a database and submission system to facilitate a community-based approach to continually updated genome annotation (http://www.pseudomonas.com). Researchers submit proposed annotation updates through one of three web-based form options which are then subjected to review, and if

12. FPC Web Tools for Rice, Maize, and Distribution1
Many clone-based physical maps have been built with the FingerPrinted Contig (FPC) software, which is written in C and runs locally for fast and flexible analysis. If the maps were viewable only from FPC, they would not be as useful to the whole community since FPC must be installed on the user machine and the database downloaded. Hence, we have created a se
