Database Connectivity

DNA barcoding and metabarcoding methods have been invaluable in the study of interactions between host organisms and their symbiotic communities. Barcodes can help identify individual symbionts that are difficult to distinguish using morphological characters, and provide a way to classify undescribed species. Entire symbiont communities can be characterized rapidly using barcoding and especially metabarcoding methods, which is often crucial for isolating ecological signal from the substantial variation among individual hosts. Furthermore, barcodes allow the evolutionary histories of symbionts and their hosts to be assessed simultaneously and in reference to one another. Here, we describe three projects illustrating the utility of barcodes for studying symbiotic interactions: first, we consider communities of arthropods found in the ant-occupied domatia of the East African ant-plant Vachellia ( Acacia ) drepanolobium ; second, we examine communities of arthropod and protozoan inquilines in three species of Nepenthes pitcher plant in South East Asia; third, we investigate communities of gut bacteria of South American ants in the genus Cephalotes . Advances in sequencing and computation, and greater database connectivity, will continue to expand the utility of barcoding methods for the study of species interactions, especially if barcoding can be approached flexibly by making use of alternative genetic loci, metagenomes and whole-genome data. This article is part of the themed issue ‘From DNA barcodes to biomes’.

Relational Database Management Systems

This chapter describes the method to retrieve data from multiple heterogeneous distributed relational database management systems such as MySQL, PostgreSQL, MS SQL Server, MS Access, etc. into Oracle RDBMS using Oracle's Heterogeneous Gateway Services. The complete process starting from downloading and installation of required software, creation of data source names using open database connectivity, modification of system parameter files, checking connections, creation of synonyms for tables of remote databases into oracle, creation of database links and accessing data from non-oracle databases using database links is explained in great detail. Apart from this, data manipulation in remote databases from Oracle and execution of PL/SQL procedures to manipulate data residing on remote databases is discussed with examples. Troubleshooting common errors during this process is also discussed.

This paper describes various aspects of web information management with particular emphasis on its application to electronic commerce. We first provide a brief overview of the web. Then we discuss concepts for web database management, as database management is a key part of information management. These include data models and architectures, query processing, transaction management, metadata management, storage issues, and integrity and security. Then we discuss various web information management technologies such as multimedia, visualization, data mining and warehousing, and knowledge management. Then we discuss emerging standards such as Java Database Connectivity, Extended Markup Language (XML), and middleware standards such as Object Request Brokers (ORB) and Remote Method Invocation (RMI). Finally we discuss how web data management technologies can be applied to the important area of electronic commerce.
