Normalization, which is the key part of the OLTP databases logical design process, is a design requirement for OLTP databases. Normalization refers to a process used to design relational database tables. Its objectives include minimizing the duplication of information within OLTP databases, as well as reducing the overall size of databases and making databases more efficient.
Checkout my article here, in which I discussed the basic guidelines for normalizing database tables to the third normal form (3NF), which helps you to meet design goals. Finally, I outlined key points that will help you decide when it is appropriate to denormalized database tables.
