I wouldn't call writing a parser easy. Unless the data is very simple (such as a CSV file), a parser can be a very complex exercise. Even the simplest tree based data structure can take hours to code for. Depending on the language it could be a real pain (try woking with a binary tree in SQL...)

Creating a good data model can also be difficult, but that depends on the scale of the data you're dealing with. You can create a relatively simple data structure in XML and have that data available to other apps in hours - and bypass the whole mess of worring about whether your other apps can parse your data format (as long as you have an API handy).
