It can be done onany relational database, where data is stored in tables that are linked to each other. This means that normalization in a DBMS (Database Management System) can be done in Oracle, Microsoft SQL
Advantages and Disadvantages of NormalizationAdvantages Eliminate modification anomalies Reduce duplicated data Eliminate data integrity problems Save file space Single table queries will run faster Disadvantages More complicated SQL required for multiple subqueries and joins Extra work for DBMS can mean ...

A well-designed DBMS reduces data redundancy through normalization and enforces data integrity through constraints and rules. Many types of databases work for different needs of the users. They also have many Servers like Microsoft SQL servers, Oracle databases, PL/SQL Language, PostgreSQL, and ...
