More Adapters on the Way

In addition to the DBKit adapters bundled in NEXTSTEP or currently shipping from third parties (see the sidebar, "Vying for Pole Position"), developers are opening the door to other leading database systems. If you need to connect with a database that is not listed, you can contact NeXT and request its monthly publication, the NeXT Database Kit Adapter Availability Guide, which is a current list of all known adapters available and under development.

If you cannot get an adapter for a database that's currently in use, you have two choices: develop your own (or pay for a third party to develop an adapter for you), or migrate to another database.
