Interview Question in Data Mining


 

Interview Question :: How data mining is differnt from sql ? please give a detail description


Data mining can be done from the web through a spider. For example, what Google does to obtain matches to its queries is a form of data mining. So is what I do when I get historical data for thousands of stocks through my own spider and analyze them for current highs. You can use a DB to store and retrieve the data you mined, and you can mine it further through queries to the DB, which are usually made through SQL, which stands for "Structured Query Language." Data mining is a process; SQL is a language that may or may not be used in that process.

RE: How data mining is differnt from sql ? please give a detail description?

Data mining is the process of finding and analyzing data that is stored in databases.



SQL is a language used to communicate with databases, telling them which data to retrieve or insert.



You normally have to use tools to do data warehousing, at the very least ETL (extract, transform & load) tools.
