After saving in the first table, execute an 'insert' command to add a new record in the second table with value of 'did'. Then use 'update' command, for the user values, on the particular record, by using value of 'did' in the 'where clause'.

I think you best use a stored proedure like:

create proc p_Insert
(
	@dna <type>,
	@ddef <type>,
 	@dsymp <type>,
	@dcompl <type>,
	@synam <type>
)
as
declare @did int
declare @syid int
insert into t1 (dna,ddef,dsymp,dc) values(@dna,@ddef,@dsymp,@dc)
set @did = scope_identity()
insert into t2 (did, synam) values(@did @synam)
set @syid = scope_identity()

select did = @did, syid= @syid

The last select query will return the new id's to your program.
