| NHibernate is a port of Hibernate Core for Java to the .NET Framework. It handles persisting plain .NET objects to and from an underlying relational database. Given an XML description of your entities and relationships, NHibernate automatically generates SQL for loading and storing the objects. Optionally, you can describe your mapping metadata with attributes in your source code.
NHibernate supports transparent persistence, your object classes don't have to follow a restrictive programming model. Persistent classes do not need to implement any interface or inherit from a special base class. This makes it possible to design the business logic using plain .NET (CLR) objects and object-oriented idiom.
Being a port of Hibernate 2.1, the NHibernate API is very similar to that of Hibernate. All Hibernate knowledge and existing Hibernate documentation is therefore directly applicable to NHibernate. Take a look at the list of Differences between Hibernate and NHibernate for a detailed comparison of Hibernate for Java and .NET or browse the available NHibernate Documentation. |

| Bamboo.Prevalence is a .NET implementation of the object prevalence concept brought to life by Klaus Wuestefeld in Prevayler.
Bamboo.Prevalence aims to provide transparent object persistence and synchronization to deterministic systems targeting the CLI. No relational databases. No object-to-relational mapping goo. No SQL. Just you and your objects. |

| Open source Code generator, D4M is an OR Mapper.
It produces C# code from your Database. Each table could be mapped to an object and its fields in properties. D4Modelizer propose a mapping schema between the database structure and the object model. |

| ODX - Open Dataset eXtensions is a quite tiny but extremely powerful ORM tool. It utilizes all the power of ADO.NET and adds the natural ease of OOP.
Object layer features:
* Inheritance (both single table & multiple table patterns). Polymorphy.
* 1:N, N:N relationships. Integrity Control.
* Lazy loading.
* Client entity cache.
* Offline mode support. Multiple server connection support. Merging data sources.
* Flexible event model.
* Save points, Persistent snapshots.
* .NET Remoting support.
* On-the-fly proxy generation.
Data layer features:
* Transactions. Optimistic concurrency.
* XML data source. Concurent access to.

| ORM.NET is Object-Relational Mapping and Code Generation Tool for .NET.
ORM.NET is an development application that auto-generates a data layer object model based on your database schema. The generated run-time component exposes all tables as classes and columns as properties.
Using the built-in DataManager object, users can easily retrieve data from multiple tables based on complex criteria without using stored procedures or embedded SQL code. In addition, data updates, inserts, and deletes can be saved to the database with one call. |

| Paladin is a generic, feature-rich object persistent framework that is architectured for today's competitive rapid application development (RAD) environment. The Paladin RAD framework comprises of two key components - a core library and a suite of tools that developers can easily use to rapidly engineer the foundation of their applications. The core library provides the basic services that are required by most applications, from object-relational mapping and automating SQL generation in the data access layer to providing transaction and simple workflow services in the business services layer. The Paladin framework also provides a powerful code generator that helps developers to automate the task of building business entity objects that are immediately usable on the framework. |

| Castle ActiveRecord is an implementation of the ActiveRecord pattern for .Net. The ActiveRecord pattern consists on instance properties representing a record in the database, instance methods acting on that specific record and static methods acting on all records.
Castle ActiveRecord is built on top of NHibernate, but its attribute-based mapping free the developer of writing XML for database-to-object mapping, which is needed when using NHibernate directly. |

| SubSonic provides a set of tools which create your Data Access Layer (DAL) for you, either at run time or from a set of generated classes. |

| OR.NET is an open source O/R Mapper and Code Generator for the .NET 2.0 Framework.
OR.NET works by generating a comprehensive data access layer in stand-alone C# 2.0 after collecting all relevant information from an intuitive GUI. |
Go To OR.Net
| Base4 is a open source platform and API for extending and integrating existing legacy and 3rd party databases.
Base4 can wrap existing data silos for you so you can re-use them rather than creating a new silo and more headaches for the future. Base4 then exposes wrapped silos using very powerful object mapping techniques.
Base4 though, is much more than an OR mapper. |
Go To Base4
| Thycotic.Data, a data access layer for .NET that utilizes late binding and allows use of any ADO.NET provider (and database) without references. Perfect for ISVs who need their products to support multiple database platforms.
Features:
* Use the same code against any database.
* Avoid including unnecessary ADO.NET providers with your application.
* Avoid the need for references to your ADO.NET providers
* Write code that will still work with future unknown ADO.NET providers.

| Cooperator Framework is a base class library for high performance Object Relational Mapping (ORM), and a code generation tool that aids agile application development for Microsoft .Net Framework 2.0/3.0.
The main features are:
* Use business entities.
* Full typed Model (Data Layer and Entities)
* Maintain persistence across the layers by passing specific types( .net 2.0/3.0 generics)
* Business objects can bind to controls in Windows Forms and Web Forms taking advantage of data binding of Visual Studio 2005.
* Supports any Primary Key defined on tables, with no need to modify it or to create a unique field.
* Uses stored procedures for data access.
* Supports concurrency.
* Generates code both for stored procedures and projects in C# or Visual Basic.
* Maintains the model in a repository, which can be modified in any stage of the development cycle, regenerating the model on demand.
