1)
Relationship between base data(workno, gertile,medium,artlast..) and reference fields are fully functional
dependent. Based on two or more attributes we can fetch other fields.
Now this table in 1st normal form. We need to conform to BCNF or 4th normal form.
---------------------------------------------------------------------------------------------------------------------------------------
2) Work no cannot use as primar key since it is unique oer record.
We need to add new column id which should be unique and it serves as primary key.
--------------------------------------------------------------------------------------------------------------------------------------
3)
Here is new tables which will be in BCNF.
Workers(ID (PK), workno,ex_date,ex_no)
kkdata6(ID (PK & FK), ex_place,ex_iilust,refs_publication .. so on)
Here id as separate attribute which will serve as primary key. Sp, two tables are connected with each
other will our unique key ID and it will be shared by both tables.

5) Yes
Work, exhibition place,exhibition data -> exhibition number
exhibition_date, place, number -> workno
These all fields are fully functional dependency.
But now with our new tables there will not be any functional dependencies.
----------------------------------------------------------------------------------------------------------------------------------------------------
6)
In both tables, ID attribute will play role as primary key, in kkdata6 table ID will play role as foreign key too..
