Enterprise Objects

■ It improves back-end portability. Database vendors have different ways of

implementing logic. If you have to support more than one database and you’re

using WebObjects, you don’t have to implement the logic multiple times and

thus suffer maintenance problems.

■ Java is a good development language. With WebObjects, you program in Java,

an industrial-strength language designed from the ground up to be

object-oriented. The programmable variants of SQL usually have some

object-oriented features, but are basically procedural languages.
