Querying Incomplete Information in Semistructured Data
Semistructured data occur in situations where information lacks a homogeneous structure and is incomplete. Yet, up to now the incompleteness of information has not been reflected by special features of query languages. Our goal is to investigate the principles of queries that allow for incomplete answers. We do not present, however, a concrete query language. Queries over classical structured d...
متن کاملQuerying Semistructured Heterogeneous Information
Semistructured data has no absolute schema xed in advance and its structure may be irregular or incomplete. Such data commonly arises in sources that do not impose a rigid structure (such as the World-Wide Web) and when data is combined from several heterogeneous sources. Data models and query languages designed for well structured data are inappropriate in such environments. Starting with a \l...
متن کاملQuerying Semistructured Temporal Data
In this paper we propose the GEM Language (GEL), a SQLlike query language, which is able to extract information from semistructured temporal databases represented according to the Graphical sEmistructured teMporal (GEM) data model.
متن کاملQuerying Linked Geospatial Data with Incomplete Information
Linked geospatial data has recently received attention, as researchers and practitioners have started tapping the wealth of geospatial information available on the Web. Incomplete geospatial information, although appearing often in the applications captured by such datasets, is not represented and queried properly due to the lack of appropriate data models and query languages. We discuss our re...
متن کاملRepresenting and Querying Changes in Semistructured Data
Semistructured data may be irregular and incomplete and does not necessarily conform to a fixed schema. As with structured data, it is often desirable to maintain a history of changes to data, and to query over both the data and the changes. Representing and querying changes in semistructured data is more difficult than in structured data due to the irregularity and lack of schema. We present a...
