Lets move on chapter 8..what we will find here is all about DATA WAREHOUSE..
Data warehouse is the place where we keep all the information...it needs to go through several process before the data keep it..
Data warehouse will work simultaneously and continually.....before this, I admit that my knowledge about IT is very poor, however, after I learn about this chapter now I have found that there is DATA WAREHOUSE to keep the information..if before this, I only know pen drive, disk, and also CD..but now, my knowledge about Data Warehouse is improved..However, there is a lot of technology that I have to study more...
There is a internal databases and external databases before the process of extraction, transformation and loading..This databases then will keep in Data Warehouse...
If we want to find the data, we can use DATA MINING, through analysis, you also can have a specific data..
If the information is wrong or there is a misstatement, we can use INFORMATION CLEANSING @ SCRUBBING to discards or weeds out...
While, Business Intelligence is to support decision making efforts..It include of TECHNOLOGY, PEOPLE, and CULTURE...
In company, if they need a high quality of information, they have to invest a lot of money in order to get it..
That's all my comment...See again...:-)
