Normal form is the basic procedure to aquire in order to remove anomalies in the database so as to make the well structure of your data and well difined in norm form there most three basic kind of norm which are 1NF, 2NF and 3NF.

The main motto of Normal form is to free from anomalies So the anomalies can be prevented through Normal form.

I think referential integrity constraints also can be used to prevent modification anomalies.

Normalisation is a technique which is used to design the best DATA BASE. It arranges the Data in the database in such a way that each database is redundant free, anomaly free & achieved data independence using different normal forms.

Different normal forms are 1nf, 2nf, 3nf & BCNF. Every database used 3nf. It is the best normal form. Because provides best decomposed relation having fully lossless join & dependency preservation.

What about referential integrity constraints. Constraints are set of rules for deciding what data is going to be stored into the database or retrieve from the database. So while considering that point I think constraints can be used to prevent modification.

Normal form used for remove the independence for data in the relation and normal form remove the duplication attribute from table.
