ipad - How to develop iphone app with database? -

-

i want develop crm iphone app. think there 2 methods deal data store, 1 using sqlite(but can not share datas others ?), other method using webservice(let app curd data 1 web application), want know better?

i think question not having 1 or other, have both: webservices expose central server somewhere common data stored , local sqlite database copy of data stored. allows fast search etc. instead of contacting remote server may or may not on-line.
