Database Normalization



What is normalization?

Normalization is very important database design ingredient, we should not assume that the highest level of normalization is always the most desirable and remember that these are worthy goals as they reduce the amount of space a database consumes and ensure that data is logically stored. A database from a local network or internet store locally on an individual computer. You need to hosting and upload on the website to create an online database. It simply means that you database is accessible over the internet. Database helps you organized information about your customers and the clients. Database helps you to work easily and to saves time. Using database, job can make easier and faster improvements than manual. Database is one of the great technologies that a business can offer. It helps employees work easily and those who work. A database is run on and accessed over the internet rather than locally. The business can choose to have it hosted on the websites so that all its departments can access and update.

Eliminating redundant (useless) data, Ensuring data dependencies make sense for example; data is logically stored is one of the advantages of database normalizations. Database has its benefits but it comes with disadvantages, One for example is complexity. Common of these things are viruses and spams. Lastly would be compatibility, There is a risk that a database might not be compatible with a client's operational requirements making it hard for the user.
Generally the higher the normal form, the more relational join in operation required to produce a specified output and the more resources required by the database system to respond to end-user queries. A successful design must also consider end-user demand for fast performance. 

Normalization has a series of stages called normal forms. The first three stage are described as the first normal form (1NF) and second is (2NF) which is called second normal form, and the third normal form is (3NF). Occasionally, it becomes necessary to stray from them to meet practical business requirements. However, when variations take place, it's extremely important to evaluate any possible ramifications they could have on your system and account for possible inconsistencies.

How do we use normalization?

When you newly create a table in a database tool, MS Access, SQL Server, MySQL, or Oracle. Oracle is the messaging solution and it is secured the Queue level access control., you won’t need all the steps that been given. The mentioned tools will help you to overcome the first normal form (1NF) already. The second normal form (2NF) will happens when the primary key is a combined attributes. And the mostly used normal form in database is the third normal form (3NF), because it will remove all transitive dependency. The database application designed that managed and accessed through the internet. Website operators are also manage this collection of data and present analytical results based on the data in web database application. Online database is a computer application that is delivered from the internet that stores and organize to make it accessible the user.
