Re: Difference between DTO and entity

DTO should not inherit from TSQLRecord, since they should be uncoupled for all persistence details.

Idea is to define custom DTO types as records or as TSynAutoCreateFields classes.

Re: Difference between DTO and entity

I just use TSQLRecord-descendants, it feels handy, simple and no over-abstraction, and so far I don't see any drawbacks.

I know people must use DDD/DTO for a reason, but so far I feel it's a little over-abstraction for my own purpose, I might be wrong
