iphone storage problem about sqlite on unity

Do you know, how can we storage game datas (database or anything) ? we dont want use userprefs because we need any database or any webstorage

last time we used to monosqlite for iphone game but it has bugs when u try to run game on xcode...

i got 2 error about this with monosqlite:

first error has come when run to game on xcode after we select build ios option on unity the error is: (IN XCODE)

Undefined symbols for architecture armv7: "__ExecuteVoidQuery", referenced from: __Z19RegisterMonoModulesv in RegisterMonoModules.o "__ExecuteFreeQuery", referenced from: __Z19RegisterMonoModulesv in RegisterMonoModules.o ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation)

secont error has come when clict to build option on unity after select non ios build in monosqlite menu and error is: (IN UNITY3D)

system.data.dll not found system.configure.dll not found sqlite3.dll s not found

any idea what can we do for this? what can we use for storage data ? TX...
