store? 1 Sep 2012, 7:06 PM I'm new to ExtJS. I wonder what the
difference between model and store is. When to use model, and
when to use store? I thought the model is the schema, and the
store is the data itself. But it seems not a right concept...
Using SQL terminology: A model is like a schema. An instance of
a model (record) is like a row. A store is like a table. 2 Sep

model contains: associations - allowing you to associate other
data stores with this model proxy - to get your data to-from
localstorage or server Can be used without a store for instance
to load and save a form with a single record. A store contains:
sorters - to sort your data filters - to sort your data group-
ers - to group your data Used for grids, XTemplate generated
views, charts and other vis
