.NET Data Access Objects

Categories: Object-relational mapping

Author: Evolve Software Technologies

Latest version: 1.3.1
Added 2004-11-02

Loosely coupled, extensible database access library written in C#.
It enables direct database access over a relational vendor-independent data layer as well as automated persistence through O/R mapping containers that work upon the data layers themselves.
Components:
- Relational data access layer: use this library to access specific data on relational databases over an abstract layer.
- Persistence Containers: an object-relational automation layer which operates upon the relational data access layer. Used to automate common data access tasks (Create, Update, Retrieve, Delete). The object-relational Mapping Unit used for automated mapping of relational data on object fields may be used standalone.
- Visual Studio Mapping Add-In: used to define mapping meta data needed by Mapping Unit / Persistence Containers. Stores metadata into XML files.
