Presently, you can work in iOS with the following databases: PostgreSQL (direct),
MySQL (direct), SQLite (the SQLite3 library required, included in iOS by default).
You need UniDAC Professional Edition with source code to develop applications for iOS.
Connection to Oracle is not supported for the time being. We will implement Oracle support as soon as Embarcadero release their compiler for iOS (For the moment, XCode and FPC are used).
Möglicherweise auch per
ODBC, wenn der Treiber im Source vorliegt und portierbar ist.
