Formal transformation of spatiotemporal data from object-oriented database to XML
نویسندگان
چکیده
With the rapid development of the Internet, XML (Extensible Markup Language) is increasingly gaining acceptance as a medium for integrating and exchanging data. Meanwhile, object-oriented database has a strong ability to store data, XML can benefit greatly and specifically from database support and object-oriented database management system. Consequently, it is significant to exchange data from object-oriented database to XML. In particular, taking spatiotemporal information existing in many practical applications into consideration, we study the spatiotemporal data models and the problem of exchanging spatiotemporal data from object-oriented database to XML. In order to find an XML Schema which is the best description of the existing object-oriented database, we propose a comprehensive approach to focus on a set of mapping functions to accomplish the transformation of spatiotemporal data.

Apply Uncertainty in Document-Oriented Database (MongoDB) Using F-XML
As moving to big data world where data is increasing in unstructured way with high velocity, there is a need of data-store to store this bundle amount of data. Traditionally, relational databases are used which are now not compatible to handle this large amount of data, so it is needed to move on to non-relational data-stores. In the current study, we have proposed an extension of the Mongo...

متن کاملAn Integrated Approach for Extraction of Objects From XML and Transformation to Heterogeneous Object Oriented Databases
CERN’s (European Organization for Nuclear Research) WISDOM project uses XML for the replication of data between different data repositories in a heterogeneous operating system environment. For exchanging data from Web-resident databases, the data needs to be transformed into XML and back to the database format. Many different approaches are employed to do this transformation. This paper address...
متن کاملTwo-Way Mapping between Object-Oriented Databases and XML
This paper presents a novel approach for mapping an existing object-oriented database into XML and vice versa. The major motivation to carry out this study is the fact that it is necessary to facilitate platform independent exchange of the content of object oriented databases and the need to store XML in a structured database. There are more common features between the object-oriented model and...
متن کاملA Vision for Management of Complex Models
Many problems encountered when building applications of database systems involve the manipulation of models. By “model,” we mean a complex structure that represents a design artifact, such as a relational schema, object-oriented interface, UML model, XML DTD, web-site schema, semantic network, complex document, or software configuration. Many uses of models involve managing changes in models an...
