- Full SQL usage (no OQL or SQL hiding. Whatever your DB/driver supports you can use).
- Stored procedure support
- No base class to extend. Works with JavaBeans, DynaBeans and our own BusinessClass base class.
- Ad hoc relationships between objects. This means that you can relate two or more objects together that you normally wouldn't. For example, in an order entry application you wan to see all the products and for each product all the customers that ordered it. Normally you wouldn't have a collection of Customer objects as a property of a Product object, but you can set this up as an ad hoc relationship and eQ! has an association object that wraps the results and it is all configured, not coded.
- Currently uss Excalibur's DataSource componet for internal connection pools with the option of using a DataSource via JNDI
- You can also get a transaction and connection directly from the persistence layer if you want.
You can see some more features and such at: http://www.browsersoft.com/eQ/technical/
There is also a free, unlimited eval license, demo you can download that is a Struts-based app with eQ!.

Hello
There's an Excalibur Datasource component, but I'm looking for a DAO manager and wondering if something already exists before I head out on my own.
Basically, looking for something like iBatis database layer (http://ibatis.com) which is essentially is a Factory + Transaction/Connection Wrapper and a Manager that puts it all together. The FortressServiceManager with the right Component Handler can be a factory, but I need something that could potentially work outside of Avalon too. Sort of a Avalon compatable DAO Manager.
I'm not sure if I'm being specific or clear enough, so if you want more details let me know. If something exists, then I'd love to use it. If not, then I may be heading over to SourceForge to create it (or if it fits within Avalon's scope, I'd donate it here).
