Navigational Plans for Data Integration
We consider the problem of building data integration systems when the data sources are webs of data, rather than sets of relations. Previous approaches to modeling data sources are inappropriate in this context because they do not capture the relationships between linked data and the need to navigate through paths in the data source in order to obtain the data. We describe a language for modeli...
متن کاملEfficiently Ordering Query Plans for Data Integration
The goal of a data integration system is to provide a uniform interface to a multitude of data sources. Given a user query formulated in this interface, the system translates it into a set of query plans. Each plan is a query formulated over the data sources, and specifies a way to access sources and combine data to answer the user query. In practice, when the number of sources is large, a data...
متن کاملEeciently Ordering Query Plans for Data Integration
We describe Streamer, the query-reformulation component of a data integration system. Given a utility measure and a user query, Streamer uses abstraction-based reenement planning and exploits information on plan independence to produce, in decreasing order of utility, a set of plans that access data sources to obtain answers to the query. We then focus on plan coverage as an important utility m...
متن کاملRecursive Query Plans for Data Integration
Generating query-answering plans for data integration systems requires to translate a user query, formulated in terms of a mediated schema, to a query that uses relations that are actually stored in data sources. Previous solutions to the translation problem produced sets of conjunctive plans, and were therefore limited in their ability to handle recursive queries and to exploit data sources wi...
متن کاملInformation Integration and Disaster Data Management (DisDM)
Recent disasters such as the 2003 SARS outbreak, the 2004 Asian tsunami, the 2005 Kashmir/Pakistan earthquake and 2005 hurricanes Katrina and Rita clearly identified the shortcomings of IT solutions for disaster rescue and recovery. Of particular note was the accompanying disaster of the lack of viable or deployed data management solutions, specifically information integration and information s...
