Normalization and its importance- Study Guides and Notes

Data in databases are usually stored in large volumes. And if we do not organize them correctly, it will be a tedious task to retrieve specific data from them. This is where normalization comes in. That means, with the help of normalization, we can reduce data redundancy and organize data more efficiently. Thus, normalization is a database design process used for database creation or data modelling. This is where we can decompose and systematically form tables to reduce data redundancy and data dependency to add, delete, and efficiently update the data. Simply put, it is a process of organizing the data in the database. For instance, we can see that an undefined table is decomposed to reduce data redundancies and data dependencies to be added, deleted, and updated efficiently.
