Objective-C: Database support

How can I connect to an Oracle database and SQL Server 20开发者_高级运维05-2008 database with Objective-C?

There seem to be few Objective-C libraries, probably because you can simply use the already available C libraries in Objective-C.

You can:

• look at MacSQL Framework (commercial)
• use any of the usual C APIs (and possibly wrap them nicely)
• use any of the C++ abstractions via Objective-C++
