This isn't related to Tiger, but we don't have a development forum, however any Tiger users in this forum must be developers, so... I'm attempting to port an app across from VB.net. It currently stores all its data in an .mdb file. Basically, I'm looking for an equivalent way to use a database (any format) in Xcode - just something simple where I can execute SQL queries and process the results. I'd preferably like to end up using a cross-platform format, so that I can update the Windows version later, to use the same data format as the Mac version. Edit: I forgot to mention that I'm new to Xcode. This is my first "real" Mac app (I've made a few little dumb apps just for learning), but I've been developing for Windows for years (mainly VB but some Pascal/Delphi and C++).
