3 Advantages of Squeryl over EOF:
4
5 * Concurrent
6 ** Spawns multiple database connections
7 ** Issues database transactions concurrently
8 * Scala Actor compatible
9 * Immutable object model/graph
10 * Strongly-typed
11 ** Better suited for business "logic".
12 E.g: Exploiting the compiler and IDE to catch exceptions at compile time rather than at run-time.
13 * Uses Scala (functional) collection classes

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

19 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.
