The store provides pattern-wide key/value storage
</Example>

The store provides key-value storage that is shared across your pattern.

If you have some information in one part that you want to make available
outside that part (in another part) you can save it to the store.

A **Store** object holds a simple key/value store with methods for storing and retrieving information.  


## Note


A store is typically used to share information between parts. For example
the length of the neck opening in one part can be used to calculate the
length for the collar in another part.
All patterns have access to
