Oracle TopLink supports access to any
data store accessible through standard JDBC using standard
SQL. Additionally TopLink offers database platforms
that allow for specific functionality to be exposed
such as native SQL, sequencing, out-join syntax, custom
date/timestamp operators and formats, and schema import
and generation with the mapping editors.
Note: The platforms and configurations listed
as certified are tested and recommended but in no way
limit the functionality of TopLink's core Object-Relational
functionality or support.
The following platforms are
provided in the installed product for both runtime and
development time use (Mapping Editors). Although these
platforms are not certified on each release their use
is still supported.
