Scope (large -> small) : Repository > Store > Factory > Others

Class Name	Read	Write	Comment
store	Y	Y	Provide cache machanism. imply signlton pattern
repository	Y	Y	the same as store, but repository have more features rather than the read/write data, e.g, update/delete data, provide metadata to archive some business goal, e,g. latest update time, sorting the items based on some rules.
source	Y	N	get the results when calling it
provider	Y	N	provide the real implementation, we use it when we try to inject the dependencies(eliminate it)
factory	Y	N	imply Factory pattern, reduce the complexity of creating objects
