I was looking for a tool like this for some time. I'm primairely interested in the conversions between rdbms types, e.g. creating Oracle and informix ddl scripts from a SQL2000 DB. Unfortunately i have a fieldtype which is used very often and it's not correctly converted by MYdbPAL, so a lot of manual work needs to be done to correct this. I am not sure if this unavoidable problem was anticipated somewhere in MYdbPAL like i saw in an other program, where additional parameters could fix this.
Furthermore, there is a lot to do about the interface, which is onorthodox, however i find it very easy to use once you understand the setup. To sum it up :A truely interesting program.
