Squeryl = SQL-like DSL for Scala

Advantages of Squeryl over EOF:

• Concurrent
  • Spawns multiple database connections
  • Issues database transactions concurrently
• Scala Actor compatible
• Immutable object model/graph
• Strongly-typed
  • Better suited for business "logic".
           E.g: Exploiting the compiler and IDE to catch exceptions at compile time rather than at run-time.
• Uses Scala (functional) collection classes

Migrating EOF -> Squeryl

In keeping with the strong-typed philosophy of Scala, Squeryl has no dynamic component like EOF (i.e an EO model file).

EOF though has the ability to generate classes in Java (and in Objective-C prior to WebObjects 4.5) enforcing type as has become customary in enterprise environments. We may exploit this feature of EOF to generate a Squeryl schema.

Create a .eogen file for your EO model as normal. Only set the File Names extension
