dao-zero is a tiny Java bean used to reduce the source of a persistence tier based on Spring's iBatis support. The usual way to use iBatis in Spring is to write code and invoke the iBatis API explicitly. dao-zero invokes the iBatis API for the developer automatically, without the need to write implementation code. It will implement DAO interfaces automatically and invoke iBatis SQL mapped statements for you. You can use it to replace your DAO bean class directly.
The OGSA-DAI Trigger component provides a mechanism to notify an OGSA-DAI server when a table in an SQL database has had its rows modified. It then executes a stored OGSA-DAI workflow to perform an action based on the notification. The trigger also provides the old and new values for the modified row which allows specific actions to be taken based on the exact database changes. These actions can use the full range of access, transformation, and delivery functionality available in OGSA-DAI.
Stab is a multi-paradigm, type-safe programming language. It will be familiar to Java and C# programmers. The compiler produces Java bytecode. Stab integrates features like lambda expressions, iterator blocks, language integrated queries, and more. It can directly use any existing Java libraries, and libraries written in Stab are directly usable from Java.
