I guess I need to understand what you mean by "native".

I know your question was to Mark Lazarus, but "native" means jobs & threads that run under the native virtual machine as opposed to the Java virtual machine, or the Unix virtual machine (PASE). And as opposed to deploying applications that run in a separate interpreted environment - like PHP.

Native has traditionally meant a transparent interface between workstations and database tables - where workstation I/O and database I/O share the same I/O buffers - or at least appear that way.


Most folks these days divide applications into separate components, running in separate virtual machines (perhaps even on separate physical platforms), using separate address spaces, communicating over sockets, and saving/restoring session data across client requests. But that kind of development is the antithesis of what a "native" developer would do.

Running entire applications in the same address space offers performance, reliability, deployment, and workload management advantages over distributed architectures. Not that people give a hoot for those things. They'd rather go merrily along, doing what most other people do.
