Fénix Framework is described as 'A framework to develop enterprise applications that need transactions, persistence, and a rich domain model' and is an app in the Development category. There are three alternatives to Fénix Framework for Windows, Linux and Mac. The best alternative is Hibernate, which is both free and Open Source. Other great apps like Fénix Framework are NHibernate .NET (Free) and JDBI (Free).
JDBI is a SQL convenience library for Java. It attempts to expose relational database access in idiommatic Java, using collections, beans, and so on, while maintaining the same level of detail as JDBC.
