mysql-diff is a commandline database structure comparator. It compares the structure of two databases. It currently works with MySQL. A database can be specified as an SQL script or as an URL to a running database. So the tool can compare two scripts, two live databases, or a database and a script. The tool outputs SQL DDL script that can be used to convert one schema to another.
The Generic Repository (grepo) is a framework for Java which allows you to access (database) repositories in a generic and consistent manner. Using grepo, it is generally no longer required to provide all the boilerplate code which is necessary in order to access (database) repositories from Java. All you have to do is write appropriate database code (queries, procedures, functions, etc.), an appropriately annotated Java interface, and very little Spring configuration.
once:radix is an integrated development environment (IDE) that operates entirely within a Web browser. once:radix supports two methods of connecting to the server. Most interest is focused on its Rich Internet Application (RIA) environment. This comes with a suite of five RIAs that perform specific roles: logging on or off, context-sensitive help, database administration, IDE, and client. In addition, the once:secureserver (oSS) can respond to commands from session-managed external Web servers.
BoneCP is a Java JDBC connection pool implementation that is tuned for high performance by minimizing lock contention to give greater throughput for your applications. It currently beats all known connection pools, including C3P0 and DBCP, as shown on the benchmark section on the site.
KeyAccess is a light-weight object-relational mapping (ORM) tool for Java, using existing databases as the starting point to generate a domain model. Its main goal is to reduce and sometimes eliminate manual updating between your domain object model and the underlying databases, while still being able to use arbitrarily complex SQL queries. In addition, KeyAccess doesn’t mandate a special architecture or framework – it will work in any application using JDBC.
CellarBoss provides a simple way to manage your wine cellar. It lets you easily update your database and includes printable reports. It uses an embedded Derby database so no separate database server is needed. The reports are created using Jasper Reports and can be printed and saved in many formats including PDF, HTML, Open Document, and XLS.
persistence4j is a small and lightweight Java object persister that uses JDBC to persist data into a relational database. The library frees you from writing the Data transfer objects - just create a POJO and simply save it. Transactional and non-transactional connections are supported and can be configured from the simple properties file.
