Dudes let me give a clarity of what he is asking.
His question is not about designing objects in object designer.
He wants to know how the object designer is designed, means how the objects are grouped,how they are maintained all those . to be more clear if we suppose object designer as Main Table , Our Main Table that is Object designer which is having fields namely Type,ID,Name,modified,Version List,date ,time,BLOB Size etc…,all these tables,Forms,reports,pages,codeunits etc… as records.
like wise he wants to know the whether we can see the design of object designer table as we see the design of item table,customer table blah blah…
