Storing data in ses_externaldata

Data that is stored in the ses_externaldata table must be either a simple datatype: int, float, bool or a Field Type.

Field Type data is stored in the database in serialized form by using the toHash() method. Simple data types (int, float, bool) are stored in serialized form.
