F. Özcan D. Chamberlin K. Kulkarni J.-E. Michels Relational database systems have dominated the database industry for a quarter century. However, the advent of the Web has led to requirements for storage of new kinds of information in which the order of information is important and data structure can vary over time and from one document to another. These evolving requirements have given rise to...

World Wide Web is the largest source of information. Most of the data on the web is dynamic and is in unstructured form. It is becoming difficult to get the relevant data from the web. Data Mining is the field of computer science which is used to extract knowledge from very large amount of data. Web mining is the application of data mining, which implements various techniques of data mining to ...

Commutative Replicated Data-Type (CRDT) is a new class of algorithms that ensure scalable consistency of replicated data. It has been successfully applied to collaborative editing of texts without complex concurrency control. In this paper, we present a CRDT to edit XML data. Compared to existing approaches for XML collaborative editing, our approach is more scalable and handles all the XML edi...

The Semantic Web is the next step of the current Web where information will become more machine-understandable to support effective data discovery and integration. Hierarchical schemas, either in the form of tree-like structures (e.g., DTDs, XML schemas), or in the form of hierarchies on a category/subcategory basis (e.g., thematic hierarchies of portal catalogs), play an important role in this...

Following the publication of the original article [1], it was brought to our attention that citation number 20 had been truncated. At current the reference reads as: ‘20. Freire SM, Sundvall E, Karlsson D, Lambrix P. Performance of XML Databases for Epidemiological Queries in Archetype-Based EHRs. 2012:51–57.’ However, it should instead read as: ‘20.
