What is the normalization process in a database?
Normalization is the process of organizing data in a database. This includes creating tables and establishing relationships between those tables according to rules designed both to protect the data and to make the database more flexible by eliminating redundancy and inconsistent dependency.

What is the purpose of normalization in OLTP?
Normalization helps in grouping like or related data under the same schema, thereby resulting in the better grouping of data. Normalization improves searching faster as indexes can be created faster. Hence, the normalized database or table is used for OLTP (Online Transaction Processing).
How are functional dependencies used in normalization process?
Functional dependencies are a very important component of the normalize data process Most database systems are normalized database up to the third normal forms. A primary key uniquely identifies are record in a Table and cannot be null A foreign key helps connect table and references a primary key
