Almost every application has to access data to do its work. Hades is an open source library that's built on top of JPA and Spring to aid the creation of DAOs by reducing the effort required.

The Hadoop Database (HBase) is well suited for creating a semantic Web and for extracting existing or computed knowledge. Learn how to represent RDF/XML assertions in an HBase database for scientific articles, and discover how HBase and Bigtable are promoting a new approach to storing and processing data.

There are a number of challenges that make the deployment task more difficult. Alex reviews the common techniques for deploying new databases and upgrading existing ones, and their flaws, and argues the advantages of an automated, incremental, script-based approach to deployments

This is part two of a series. In this installment, I explore the need for reliable builds in the database world.

Whereas the RDBMS uses SQL as its principal mechanism for finding and retrieving data, an OODBMS can use one of several different mechanisms. This second installment introduces a few of the options, including Query by Example and custom mechanisms unique to the OODBMS. As he explains, some of the alternatives can be easier to use than SQL itself.

HTML5 will reshape the web experience and line-of-business applications. With the offline capabilities and local persisted storage features, you can deliver the same rich user experiences online and offline that were previously available only in proprietary desktop application development frameworks. In this article, learn how to leverage HTML5 offline capabilities and local persisted storage features. An example application illustrates how to avoid common problems.

Although many of the important tasks a DBA has to perform should be done 'by hand', keying in commands or using SSMS, the canny DBA with a heavy workload will always have an eye to automating routine tasks wherever possible, or using a tool. Although the likely candidates for automation are often obvious, it is not always so. Time can often be saved in surprising ways.

People love Ajax applications so much that they are willing to use them instead of their desktop equivalents. The only problem occurs when they fail to have network access. This is when an offline feature is necessary. Apache Derby is a great option for enabling offline access to Ajax-powered applications. Learn how to use Apache Derby as a local data store that can be used to take your Ajax application offline.

As mobile developers, our applications will need to both aesthetically display the results of our data queries, as well as give users an intuitive interface to store and insert data. In this article by Jason Wei, author of Android Database Programming, we will focus on the former – on binding data to the user interface (UI) and will look specifically at various classes that will allow us to bind our data in the form of lists (the most common and intuitive way to display rows of data).

There aren't many frameworks for writing acceptance tests for databases, including SQL Server. FitNesse is an obvious choice since it is designed with a Wiki-style interface that, once it is configured and set up correctly, makes it very easy for a non-specialist to set up individual tests.
