I have just enabled the below caches in web config file, now how to see the cache is storing in particular location or not ? If so which file or database table i have to check ?

<setting name="Caching.Enabled" value="true" /><setting name="Caching.ItemCachingEnabled" value="true"/>

and

<databases><database id="web"><cacheSizes role:require="ContentDelivery or Standalone"><data>500MB</data><items>500MB</items></cacheSizes></database></databases>
