Consistency of Spatial Database Query Results
نویسنده
چکیده
Numerous applications involve the use of a Geographical Information System (GIS). A working session consists of several spatial database orders. The scope of this paper is to provide a link between alphanumeric data and spatial representation of objects stored in a GIS database. The notions of Granule, Topology and Set_relationship are defined to guarantee a semantics to alphanumeric data parts associated to the results of spatial database queries.

Consistent Query Answering under Spatial Semantic Constraints
Consistent query answering is an inconsistency tolerant approach to obtaining semantically correct answers from a database that may be inconsistent with respect to its integrity constraints. In this work we formalize the notion of consistent query answer for spatial databases and spatial semantic integrity constraints. In order to do this, we first characterize conflicting spatial data, and nex...
متن کاملAnalysis of User query refinement behavior based on semantic features: user log analysis of Ganj database (IranDoc)
Background and Aim: Information systems cannot be well designed or developed without a clear understanding of needs of users, manner of their information seeking and evaluating. This research has been designed to analyze the Ganj (Iranian research institute of science and technology database) users’ query refinement behaviors via log analysis. Methods: The method of this research is log anal...
متن کاملPre - Processing Queries with Spatial Constraints
This paper discusses strategies for pre-processing spatial queries before executing them in a geographic database. A computational method has been devised, which is capable of assessing whether or not a spatial query is consistent, i.e., that its constraints are free of any selfcontradictions. If the query is inconsistent, it can be rejected immediately without a need to process it in the datab...
متن کاملI-SQE: A Query Engine for Answering Range Queries over Incomplete Spatial Databases
Spatial database systems built on top of distributed and heterogeneous spatial information sources such as conventional spatial databases underlying Geographical Information Systems (GIS), spatial data files and spatial information acquired or inferred from the Web, suffer from data integration and topological consistency problems. These issues make the globally-integrated spatial database inco...

Deductive Database systems are designed based on a logical data model. Data (as opposed to Relational Databases Management System (RDBMS) in which data stored in tables) are saved as facts in a Deductive Database system. Datalog Educational System (DES) is a Deductive Database system that Datalog mode is the default mode in this system. It can extract data to use outer joins with three query la...
