TSQLObjectData is used in TBufferSQL2 class in reading procedure.
Keeps the data requested from the SQL server for an object.
It contains data, request from database table for one specifc object for one specific class. For instance, when data for class TH1 required, requests will be done to TH1_ver4 and TH1_raw4 tables and result of these requests will be kept in single TSQLObjectData instance.
