Getting data is probably the thing you'll do most once you start coding anything with JAS. There are roughly 6 different ways of doing this, each having their pros and cons. Depending on what data you want to get one way might be better than the other. Here's a quick overview of the various methods:

• Item, get an individual item based on its ID
• List, get a list of items for a certain category
• All, get all items or filter on specific (combinations of) columns
• Filter, advanced filtering with nested values and "deep" references filtering
• Tree, get a tree of items (categories and their sub categories)
• Search, text searches
