One of the unique facilities of this model is the implementation of application across the numerous servers. This is the main reason for the cloud creating technology to be busy in the market. It has attracted the organization where they find hard to balance their business and to integrate them after its diversification.This model offers certain standardized application.

Cloud data base model provides more advantages than the relational database model. Open source application is more practiced source in most of the application where it opens rarely in relational model. Open source is better than the Windows Azure and Google application. But most of the business people prefer cloud model as they have the capability of supporting most of the application that helps during the critical business application.

Dynamics schemes are easy to share through the cloud computing technology as this application helps the employees to continue their work without any delay or troubles during the process. Cloud format is mostly preferred by the people as it provides full support with the algorithm format.  However they also face certain troubles while transferring the cloud from an RDBMS which is a run application.

Data base normalization

database normalization

It is a serious used to obtain the database designs where it allows the consistent storage and the efficient access of the data in relational database. On the other side it is called as the process of organizing data efficiently in a database. Steps involved in the data process are as follows elimination of redundant data (storing similar data in many table), ensuring the data dependencies that make sense. It reduces the data redundancy and as a chances of occurring the data inconsistency.

We have certain number guidelines set to ensure whether the database is normalization. It is refer ed to normal forms and are numbered from 1 to 5. Most of the commonly used application is 1NF, 2NF and the 3NF and occasionally 4NF and the 5th one is seen rarely.

In case of 1NF it sets a basic rule for the organized database – eliminates the duplicative column from the similar table, creates separate table for each and every related data and helps to identify the each row with its column.
