Data Mart, Data Mining and Data Warehouse?
Hi.
I am a newly grad of BS Information Technology.
Unfortunate, in our school, we only studied DATABASES. And I loved it. When I got in to my internship, I encountered DATA MART, DATA MINING and DATA WAREHOUSE. I tried to make a research of these within that company, but its too difficult because they are talking in a much higher level. I mean they are being too technical (though my boss there tried to teach me about those things, and Im thankful with that). Now, I am so interested with those things. Can somebody give me some good sites where I can easily study those things? And also, can somebody tell me how these things differ from each other or what are there main functions?
Thanks...
Well, there is a lot about data marts, data mining and data warehouse. It can be read through websites. I guess you have researched enough to read it on the website. So, its time to read a book on data warehousing. Find out the integration method your company is using. If its a bottom-up integration then you use the Kimball method. and if its to-down integration then its Inmon method.
Data marts are objects pertaining to a certain subject area like sales, finance. Data warehouse is the collection of these data marts. Data mining is the analysis of the data which helps in making a business decision...I guess u already know it by this time.
Well, I suggest you read the Book called Data warehousing by Ralph Kimball. He is the best.
I'm sure that by reading this book, your life becomes a lot easier at work. I am a professional working in this field for 5 yrs now and I love it.
