Schema-Mediated Exchange of Temporal XML Data
When web servers publish data formatted in XML, only the current state of the data is (generally) published. But data evolves over time as it is updated. Capturing that evolution is vital to recovering past versions, tracking changes, and evaluating temporal queries. This paper presents a system to build a temporal data collection, which records the history of each published datum rather than j...
متن کاملA Workbench for Prototyping XML Data Exchange
This paper describes a prototype software which is the outcome of a research carried at the Ca’ Foscari University of Venice in the framework of the project Data-X1. The software is a workbench for “data engineers”, integrating several tools which assist the user in all the tasks of integration and exchange of data with a standard format, for instance for application integration, generation of ...
متن کاملGIS data exchange problems, solutions
Publised in Periodica Polytechnika 1999 Abstract The present situation in Hungary is introduced in the field of GIS data exchange in this paper. Most of the data exchanges concentrate on map data (graphical data) without attributes. The new Hungarian standard DAT1 (MSz 7772-1) has changed the situation. It involves map, topology and attribute data as well. This is the official data exchange for...
متن کاملTemporal XML Data Warehouses: Challenges and Solutions
Increasing amounts of data is stored in XML. In order to facilitate more efficient querying on this data, and in particular on data from several sources (for example Web sites), data can be loaded into an XML data warehouse. Often, we want to query historical document versions, or query changes between document versions. This can be facilitated by a temporal XML data warehouse (XML-DW). In this...
متن کاملSolutions and query rewriting in data exchange
Data exchange is the problem of taking data structured under a source schema and creating an instance of a target schema. Given a source instance, there may be many solutions – target instances that satisfy the constraints of the data exchange problem. Previous work has identified two classes of desirable solutions: canonical universal solutions, and their cores. Query answering in data exchang...
