possible merge the two sections in one with a title "Creating a Store" and rephrase to:
"To create a store, invoke DataManager store factory method, passing along a StoreConfig object, with the type set to either StoreTypes.MEMORY for an in-memory backed store, or StoreTypes.SQL for an sqlite backed store. A  name should be also provided to distinquish between different stores that this DataManager can hold.

<code snippet for memory> 
Note: A Memory store will go away when the application is removed from memory and is best suited for short term caching.

<code snippet for sqlite>
Note: for an SQLStore you will need to make sure that 'open' has been called before you can access it.
