Delphi has already Multi-Tier / Layered architecture available since early versions. You were never limited to RAD components.

DataSnap is certainly the de-facto standard version of building such applications. See e.g. this article from Embarcadero.

Other Service-Based frameworks written on Delphi are available (DataAbstract, RemObjects, KBMMw, Midware, WST, Synopse, Spring).

ORM framework are a good way of creating multi-tier separated applications (e.g. InstantObjects, DObject, tiOPF, GFramewok, Bold, Synopse, hcOPF, DelphiORM..). Some of them even allow to build Services above ORM. See for instance our Open source framework.

There are others available as well, like hcOPF
