MDT is modified data tag.
MDT is one bit of the attribute character.
MDT is off(0), it indicates that this field has not been
modified by the terminal operator.
MDT is on(1), it indicates that this field by the
terminatal operator.
FSET is field set. MDT will be set on(set to 1) regardless
of whether the terminal operator modified the data or not.

Answer / saths

Suppose you display a map and consider the function of that map is to update.To update ,first u fetch a particular record with some id(primary key) . Suppose there are 3 field name ,mark 1, mark2 and you
Just updating mark1 alone.Then
Mdt for name = 0
Mark1 = 1
Mark2 = 0
, So that only mark1 get updated . Name and mark2 will be null.
In order to avoid that we go for fset
Fset will set mdt value for all feild as 1
So ur update will processed perfectly.So, ur name and mark2 will be same as pervious value.
Frset is used to set mdset = 0 for all feild.
