Well every one have the question while joining the data warehousing training institute, the following article may help you understand why?
Following are the some of the benefits of the data warehousing in Industry.
Before the data is loaded into the database it has to be cleansed, in effect this involves identifying and resolving all the dirty/inconsistent data. By doing this before the data is loaded into the database the actions of reporting and analyzing data are greatly simplified.
Once it has been loaded into the data warehouse the information is under the control of the user. This allows for the information in the warehouse to be stored safely for extended periods of time, even if the source system data is purged over time,
Another great advantage of using a data warehouse is that they are separate from any operational systems. This means that they can perform retrieval of data operation without interfering with any operational requirement of the system.
Data warehouses is also able to work in conjunction with, and by doing so enhance the value of, operational business applications, the most notable of which being customer relationship management (CRM) systems.
Data warehouses are generally used to facilitate applications associated within the decision support system. These applications will deal with reports concerning trends, for example what was item had the best sales in what area over the last year, exception reports, and reports that show actual performance versus goals.
The ability of data warehousing to compile, analyze and report information from different sources to give valuable information quickly rather than trawl through information from different sources in different formats is priceless in this age of instant decision making.
Some of the applications data warehousing can be used for are:
* Decision support
* Trend analysis
* Financial forecasting
* Churn Prediction for Telecom subscribers, Credit Card users etc.
* Insurance fraud analysis
* Call record analysis
* Logistics and Inventory management
The only thing that you have to do while joining any training institute is that always makes a background check on that training institute.
As I'm also a student, I think the best way to choose is to list out the different institute in Bangalore and from that you extract the best you thing and attained 1 class for each institute.
And decide which you think is the best for you and one more important thing always ask the students from the different institutes that how they fell the class.
This worked for me I guess it will also work for you. ! ! !
