I need to make a program, which will have about 1000 articles in it. Articles are grouped by categories, one article can be under more than one category. Users can browse through articles through categories (iphone tables will be used here) or through full text search. There will be hyperlinks in articles too, they will lead to another article. What would be a good way to store all this data on iphone? Haven't worked with sqlite or core data yet, only have experience with mysql, but that's absent on iphone. Any advice?
