In a short span of time this data becomes so huge making it necessary to have a system that can store and use it. The solution that came into existence was Database Management System. Journey started from Simple Text file to RDBMS to ORDBMS.

What separate a Big data from a huge data? I have seen the abuse of Big Data being adopted by the database and BI vendors. It lacks the spirit. Merely calculating faster or storing more should not qualify for a Big Data thinking. It is purely technological breakthrough - just like having a faster CPU. Will you call an intel CPU i7 a change of era from i5? Here are my observations and principles to be Big Data:
1. Collect the impossible
With the emergence of e-government, more…Continue
In recent years, I proposed three new kinds of data structure to represent itemsets. They are Node-list , N-list , and Nodeset . They use prefix-tree nodes to represent itemsets instead of the set of tranaction ids.
Since prefix-tree is usually high compressed, Node-list , N-list , and Nodeset  are much shorten than Tidset or diffset, which are two classical vertical representatnion of itemsets. Therefore, for frequent itemset mining, the algorithms based on Node-list,…

Here is an excerpt from a TDWI article - "The Year in BI and Data Warehousing" - that was published in December 2013.
"One of the things that ailed BI in 1993 and 2003 is the same thing that ails BI today: i.e., anemic adoption. This is in spite of the fact that today's BI tools incorporate a staggering array of "self-service" features, along with (often…Continue
