It is intended to be useful to both developers using one of these databases for the first time as well as for those who regularly interaction with multiple databases.

Opinions about ORMs vary widely. Some see it as an essential tool for simplifying data access while others claim it greatly increases complexity while robbing applications of much needed performance. Sam Saffron and Rob Conery have found a middle ground in what’s known as a Micro ORM.
Lance Ball presents DataMapper, a Ruby ORM library, along with Infinispan, Hibernate Search, Lucene, all running on JBoss AS7 and accessed through TorqueBox, a JRuby application server.
Burt Beckwith discusses potential performance problems using mapped collections and Hibernate 2nd-level cache in GORM, along with strategies for avoiding such performance penalties.

In this interview, Jimmy focuses on LINQ to SQL and ORM. Jimmy has tried to create a similar technology to LINQ to SQL in the past, but without similar results. While LINQ to SQL is a step in the right direction, .NET still lags behind other programming languages in object-relational mapping capabilities.
