This is hierarhical structure, which is created when data is written by TBufferSQL2.

It contains data all structurual information such: version of written class, data memeber types of that class, value for each data memeber and so on. Such structure in some sense similar to XML node and subnodes structure Once it created, it converted to SQL statements, which are submitted to database server.
