Usando Entity Framework com o Oracle

8. May 2009 08:07

Dois fornecedores já estão disponibilizando  providers que visam permitir o uso do modelo de mapeamento do Entity Framework com o banco de dados Oracle. Com essa integração você vai usar todo o poder do LINQ (Language Integrated Query) para criar consultas em cima dos objetos mapeados do banco de dados.

dotConnect for Oracle

Connect for ADO.NET Entity Framework provider for Oracle
http://www.datadirect.com/products/net/beta/index.ssp

A proposta do Entity Framework para você que está chegando agora é chegar no tão sonhado momento de suportar os principais bancos de dados do mercado sem precisar fazer alterações em todo o seu código.

Uma coisa legal que você precisa entender é que não vamos mais fazer querys usando o T-SQL e sim usaremos o LINQ e o mecanismo do Entity Framework em conjunto com o seu provider vai gerar o código necessário compatível com o banco de dados.

Realmente o Linq é muito interessante...

Não tinha tido um grande contato aida com a tecnologia,  mas agora no meu novo emprego iremos utilizá-la e estou bastante empolgado com a idéia!!!

Já dei uma lida, assisti uns webcasts e a tecnologia realmente é muito legal.

Até mais.

Espero realmente que o Entity Framework em sua nova versão no .Net Framework 4.0 venha com mais funcionalidades incorporadas e quem sabe com um acesso nativo ao Oracle. Smile

Eu comprei o dotconnect for oracle e estou muito satisfeito com a ferramenta.
Minha aplicação é ASP.NET MVC e LINQ to Oracle. O problema é a memória vai aumentando até usar o máximo do servidor 4GB.
A pergunta é, eu devo ou não chamar o dispose() do datacontext? Já vi gente falando que sim, já gente falando que não. Não sei se esse é o meu problema.

Modern understanding of the art of many cultures tends to be distorted by the modern privileging of fine art media over others, as well as the very different survival rates of works in different media. Works in metal, above all in precious metals, are liable to be "recycled" as soon as they fall from fashion, and were often used by owners as repositories of wealth, to be melted down when extra money was needed. Illuminated manuscripts have a much higher survival rate, especially in the hands of the church, as there was little value in the materials and they were easy to store.

Oops this is odd that my comment got eaten. However I want to tell that it's good to realize that someone else also told this as I had trouble locating the exact info elsewhere. Also, interesting submission. A big part of readers don't think that every sites should have comments section. On the other hand I believe that user comments characterize a blog. So thanks a lot for permitting us posting on this well designed page. Sincerely yours.
