NHibernate - Banco de dados Suportados pelo NHibernate

Atualmente os principais banco de dados suportados pelo NHibernate são:

Microsoft SQL Server 2008/2005/2000

Oracle

Microsoft Access

Firebird

PostgreSQL

DB2 UDB

MySQL

SQLite

Com base nisso segue uma tabela contendo o código para o arquivo de configuração do NHibernate usado para cada um destes bancos de dados.

O arquivo de configuração define as informações do provedor, dialeto, driver e string de conexão do banco de dados usado para persistência.

Lembrando que podemos realizar esta definição no arquivo de configuração da aplicação (app.config ou web.config) ou no arquivo

NHibernate.cfg.xml;

Obs: A sintaxe usada nas configurações referem-se a versão 2.1.2 do NHibernate e não devem ser usadas em versões anteriores.

Obs: Atente para o fato que você deverá alterar a string de conexão usada nos exemplos acima.

Recentemente foi lançado o NHibernate 3.1.0 veja detalhes em : http://nhforge.org/Default.aspx
