Normalization is the process of reorganizing data to reduce redundancy. See here[^] for more details on Normalization.

What you are trying to do here is actually a JOIN. You are joining two tables (with menuid acting as the foerign key).
For eg, to get multiple submenus for menu id 4, your query will look like
select * from A, B where A.menuid = B.menuid and menuod = 4
