Among various sharding implementations, Hibernate Shards is possibly the most popular in the world of Java technology. For some shops, sharding means being able to keep a trusted RDBMS in place without sacrificing data scalability or system performance. In this installment of the Java development 2.0 series, find out when sharding works, and when it doesn't, and then get your hands busy sharding a simple application capable of handling terabytes of data.

JDBC, or Java Database Connectivity, is one of the most frequently used packages in the entire JDK, and yet few Java developers use it to its fullest — or most up-to-date — capacity. This article offers an introduction to newer JDBC features.

Take a look at CouchDB from a PHP developer's point of view, and learn how CouchDB gives you a document-based, schema-free, ad-hoc database with a flat address space. Learn how you can add CouchDB to your technical toolboxes to create and delete databases, work with CouchDB views, and more.

Database security is the single biggest concern with today's Web-based applications. Without control, you risk exposing sensitive information about your company or, worse yet, your valuable customers. In this article, learn about security measures you can take to protect your PostgreSQL database. Be sure to download the sample code listings used in this article.

Tap into vast amounts of fielded information stored in a publicly accessible collection called DBpedia. With a little CGI scripting, build forms that drive a SPARQL query under the covers, with access to the semantic Web's largest database for people who've never heard of the semantic Web.

CouchDB is an open source document-oriented database-management system, accessible using a RESTful JavaScript Object Notation (JSON) API. CouchDB never claimed to be a replacement for relational databases, but it has become increasingly popular in Web applications, iPhone applications, and Facebook applications. See how CouchDB stores data in a semi-structured fashion, using a JavaScript-based view model
