What is the purpose of using joins in database is normalization the only purpose of it?
The purpose of using Normalization is to avoid the data redundancy in tables. The normalized schema is much faster in performance so you can get a quick response from the database.
OLTP database designers follow the Normalization rules but the tables in Data warehousing(OLAP) data bases are in the De normalized form, they won't follow the Normalization technique. For this reason we are using more complex queries in Data warehouses which uses more system resources.
Some one might explain you better way.........
Thanks

A database is a collection of tables that is used for some purpose (typically an application of some sort).

What is normalisation in GIS?
Normalization in GIS refers to the process of standardizing data values within a specific range or scale. This is done to minimize the impact of different measurement units or scales when analyzing or comparing data from heterogeneous sources. Normalization helps ensure that data sets are comparable and can be used effectively in spatial analysis and modeling.
