PlantCFG:A comprehensive database with web tools for analyzing candidate flowering genes in multiple plants

Dear Editor,The transition from the vegetative to the reproductive phase of plant development,known as the floral transition,plays important roles in the plant life cycle.Flowering is a vulnerable but crucial phase for building crop yield,and proper timing of this period is therefore vital for obtaining optimal yields(Jung and Muller,2009).Analysis of flowering time is currently an important research topic in several fields,including plant molecular genetics,evolutionary biology,ecology,and crop breeding(Huang et al.,2011).

Rules-based object-relational databases ontology construction

To solve the problems of shaving and reusing information in the information system, a rules-based ontology constructing approach from object-relational databases is proposed. A 3-tuple ontology constructing model is proposed first. Then, four types of ontology constructing rules including class, property, property characteristics, and property restrictions ave formalized according to the model. Experiment results described in Web ontology language prove that our proposed approach is feasible for applying in the semantic objects project of semantic computing laboratory in UC Irvine. Our approach reduces about twenty percent constructing time compared with the ontology construction from relational databases.

New Trend of Database for the Internet Era ——Object database and its application

And also we introduce object database and its efficiency, which will be the new trend of the database. We use “Jasmine2000” as a concrete example of object database in business use, and are going to verify its efficiency with its applied cases. At the end, we will point the way of database's future.

An OWL-Based Specification of Database Management Systems

In the context of a proliferation of DatabaseManagement Systems(DBMSs),we have envisioned and produced an OWL 2 ontology able to provide a high-level machine-processable description of the DBMSs domain.This conceptualization aims to facilitate a proper execution of various software engineering processes and database-focused administration tasks.Also,it can be used to improve the decision-making process for determining/selecting the appropriate DBMS,subject to specific requirements.The proposed model describes the most important features and aspects regarding the DBMS domain,including the support for various paradigms(relational,graph-based,key-value,tree-like,etc.),query languages,platforms(servers),plus running environments(desktop,Web,cloud),specific contexts—i.e.,focusing on optimizing queries,redundancy,security,performance,schema vs.schema-less approaches,programming languages/paradigms,and others.The process of populating the ontology with significant individuals(actual DBMSs)benefits from the existing knowledge exposed by free and open machine-processable knowledge bases,by using structured data fromWikipedia and related sources.The pragmatic use of our ontology is demonstrated by two educational software solutions based on current practices in Web application development,proving support for learning and experimenting key features of the actual semantic Web technologies and tools.This approach is also an example of using multiple knowledge from database systems,semanticWeb technologies,and software engineering areas.
