The advantages of data normalization can be very large in terms of storage space as well increased efficiency with which data can be updated & maintained the rules of normalization or normal forms define exactly what kind of information can placed in each table and how this information relates to the fields. There are many advantages of performing a database normalization some of the advantages include faster index searching, data commands are faster with less indexes and a more compact database with less null data. Normalization is a systematic way of ensuring that a database structure is suitable for general-purpose querying and free of certain undesirable characteristics—insertion, update, and deletion anomalies—that could lead to a loss of data integrity.
The benefits of normalization include: searching, sorting, and creating indexes is faster, since tables are narrower, and more rows fit on a data page you usually have more tables you can have more clustered indexes (one per table), so you get more flexibility in tuning queries. Database normalization is the process of organizing data within a database in the most efficient manner possible for example, you likely do not want a username stored in several different tables within your database when you could store it in a single location and point to that user via an id instead. When mixing normalization and denormalization, focus on denormalizing tables that are read intensive, while tables that are write intensive keep them normalized ovaistariq ovais is a storage architect with keen focus on reliability, efficiency and performance of oltp databases, more specifically mysql. When using a relational database, normalization can help keep the data free of errors and can also help ensure that the size of the database doesn't grow large with duplicated data.
