The availability of data on the Web and new data extraction technologies have made it increasingly easy to reuse existing data to create new databases and provide value-added services. Meanwhile, database creators have been seeking legal protection for their data, such as the European Union’s Database Directive. The legislative development shows that there is significant difficulty in finding t...

This note outlines some of the key intellectual obstacles that stand in the way of creating a usable phylogenetic database. These challenges include the need to accommodate multiple taxonomic names and classifications, and the need for tools to query trees in biologically meaningful ways. Until these problems are addressed, and a taxonomically intelligent phylogenetic database created, much of ...

Different functional components focus on matching life science ontologies, detecting and keywords, readability and a short abstract on what the given text is about between database schemas and ontologies as well as between different. By creating connections between these two ontologies in a mapping ontology, the user defines Different templates can be created to access different database schema...

Database Switching includes execution of queries on same or different machines connected in LAN with different backend without rewriting any queries. Switching between the databases reduces the work of rewriting the queries for each of the database thus saving time. User just has to select the Source DBMS and Table from that DBMS and a switch file is created on a click of a button. Now this swi...

This paper presents an approach to maintaining consistency of object versions in multiversion database systems. In this approach a multiversion database is considered to be a set of logically independent and identifiable database versions. Each database version is composed of a version of each object stored in the system. However, identical object versions may be shared by many database version...
