Data: Information processed or stored by a computer system
Database: A systematic collection of data. An electronic system that allows data to be easily accessed, manipulated and updated
Data warehouse: A structure place to store data designed to optimise for various functions. It is a relational database designed for query and analysis
A data warehouse is a type of database but designed for optimised analysis.
Data mart: Is a subset of a data warehouse meaning it focuses on one task. Purpose is to isolate and partition a smaller set of data from a data warehouse so there is easier access for the end user.
Data mining: The process of analysing hidden patterns of data according to different point of views for categorisation into useful information. Collected in data warehouses for efficient analysis. It allows us to analyse trends in data usually for commerce related reasons. There is so much data that they are needed for organisation and finding trends. EXTRACT - STORE - PROVIDE - PRESENT
A data warehouse extracts data and data mining takes this data and uses it for finding trends

I thought I was dumb when I didn’t know what data mining was. Now I feel even dumber that I still don’t know what it means.

Prof. Kudyba is one of the best professor in NJIT. I have learnt many techniques in data mining from him.

This is a very nice video and useful information regarding data mining, the most challenging thing is actually applying it to organizational decision making process, , , it is indeed a lot of work to actually successfully data mine. I must confess that building the database is really easy and straight forward but data mining is wow, hard work.

From my understanding you pull data from tables that give you the info you are looking for. Need to know what is your most popular selling item? Pull the sales tables and see which item has the most transactions. Had a hard time understanding this because my work has its own database for dummies where you just have to fill in lines with what you want. A data miner would know what queries to write to pull the data without such a system in place.

What is the difference between Data Mining, hacking, and sharing of private information

[agstechnicalsupport]

A good definition of data mining. Thank you !

Data mining is taking the supermassive amounts of data of any kind and utilizing mathematical methods in order to identify trends.

Will data mining be automated in the no too distant future? Is the industry due for disruption?

[NoahBurkes]

What database software do you recommend for large scale production?

Artificial intelligence is soon going to replace data mining

So basically this video is about how data mining is important not what it is -_-

What about use for education, and even employment, education direct to the desktop and compile your Ph.D. as you go.
