Review comment:
       Why is this variable static? Wouldnt we have an issue if multiple queries were being processed at a time?

Review comment:
       a) I think we should call this method isDbRemote() or isDatabaseRemote() instead of getIsRemoteType()
   b) this should be either a protected method so its only used by its sub-classes? being doesnt make much sense given the return value is specific to a database but it doesnt take any arguments. Or if we want to make it static, we can add a isDatabaseRemote(Database db) method to a utils function.

Review comment:
       if we make it an instance method, we will not need the classname to invoke it.
