Normalization is the technique of dividing the data into multiple tables to reduce data redundancy and inconsistency and to achieve data integrity. ... In contrast, denormalization reduces the number of tables and join. Disk space is wasted in denormalization because same data is stored in different places. 19) What are DB constraints a.
