ETA is an ORM (object / relational mapper) built for .NET 2.0. It supports multiple storage devices (sql, xml, flat file, etc), using the provider pattern. It supports desktop or web applications. It doesn't require a table mapping file; uses only 1 line of configuration. Also supports tagging (think del.icio.us) out of the box. The syntax is simple and natural.

Not only that, unlike other systems that support html generation of admin pages, ETA comes with a desktop administration application for any entity types you can make.

The ETA system is a Middle Ware layer between your code and your storage mechanism. Reference it in your Business Logic Layer, and create your application on top of it.

I love this system because it's easy to use, totally dynamic, and flexible to change. In fact, it run's this website's back end. Each of my Blog Posts, Projects, etc are entities persisted by ETA.

Although I do love it, this system wouldn't be good for enterprise scale use. This is because in order to achieve the easy syntax that I wanted, every save/load operation consists of 2 layers of .NET Runtime Reflection and a hit to the database. If you have a high volume website or large application, this probably wouldn't be as performant as you need.

For version 2, I want to upgrade to .NET 3.0 and integrate with LINQ for my searching mechanism. Right now, it's all code based (very slow).
