Without normalising your data, you are effectively using an excel spreadsheet-esque design to store all of your data contiguously.
This introduces update / delete / insert user errors a critical design flaw, in that if say, an order needed an item adding / deleting / updating then all data tied to that order must be altered as well.
You will also generate a great deal of redundant data, which can consume space rapidly in a large database. In the above example you would have to repeat all the order and customer details for every item on each line over and over.
Data in a flat format will also be highly difficult to query for statistics, in part due to the layout of the data itself and in part because of user error, for example if you wanted to count the number of times your polish customer had placed an order (Mr Zbigniew Dmartchyzk), in a flat database your 100 data in-putters are probably going to fail at spelling that correctly every time, so you could end up with a hundred or so different spellings and no method of querying the data correctly.
If you start to separate the data into separate tables in any way, you have already begun the process of normalisation.

Normalization form in details in points and examples?
Normalization is a process to reduce redundancy. By using normalization we can easily remove duplicate entries..
Is The process of normalization is reversable?
Yes, the process of normalization is reversible. Normalization is a database design technique that organizes data in a relational database to reduce redundancy and improve data integrity. You can always revert the normalization process by denormalizing the database if needed.
What is normalization and objective of normalization?
Normalization is the process of organizing data in a database to reduce redundancy and dependency. The objective of normalization is to minimize data redundancy, ensure data integrity, and improve database efficiency by structuring data in a logical and organized manner.
What is the purposed normalization in database?
The purpose of normalization is to reduce the chances for anomalies to occur in a database. The Normalization also forces you to use a database in a Object orientated manner. (This is good of course.)

Why normalisation necessary during database design?
Database normalization, or data normalization, is a technique to organize the contents of the tables for transactional databases and data warehouses. Normalization is part of successful database design; without normalization, database systems can be inaccurate, slow, and inefficient, and they might not produce the data you expect.
Describe database normalization?
Database Normalization is the process of organizing the fields and tables of a relational database to minimize redundancy and dependency
