Class DBCreator

java.lang.Object

net.as_development.asdk.db_service.impl.backend.creator.DBCreator

public class DBCreator
extends Object

Provides more comfort around creating and updating DB schema. It uses the interface IDBSchema of a IDB instance. It's implemented there because there exists all needed meta information and the needed access to the back end. Here we implement some stuff around that as e.g. command line interface, flexible API and more.
