What is the difference between Big Data and Hadoop? Online Training Hyderabad

Big data Hadoop training in Hyderabad

Big data is a marketing term, not a technical term. Everything is big data these days. My USB stick is a "personal cloud" now, and my harddrive is big data. Seriously. This is a totally unspecific term that is largely defined by what the marketing departments of various very optimistic companies can sell - and the C*Os of major companies buy, in order to make magic happen.

Actually, data mining was just as overused... it could mean anything such as

collecting data (think NSA)
storing data
machine learning / AI (which predates the term data mining)
non-ML data mining (as in "knowledge discovery", where the term data mining was actually coined; but where the focus is on new knowledge, not on learning of existing knowledge)
business rules and analytics
visualization
anything involving data you want to sell for truckloads of money

It's just that marketing needed a new term. "Business intelligence", "business analytics", ... they still keep on selling the same stuff, it's just rebranded as "big data" now.

Data quality suffers with size

Many of the marketing promises of big data will not hold. Twitter produces much less insights for most companies than advertised (unless you are a teenie rockstar, that is); and the Twitter user base isheavily biased. Correcting for such a bias is hard, and needs highly experienced statisticians.

While preparing to help THEM prepare, We created this quick list of 14 tips, tricks and advice -- We hope you find it useful! 1.) Exam Format: This is a timed, multiple choice exam. There are 60 questions you must answer within a 90-minute window. Some questions have one answer, some have multiple correct answers (and you must select all of them correctly). The advantage of a multiple choice format is that all of the information is in front of you. The disadvantage is that additional information is also given to you, designed to confuse you. Some people excel at this format and never have to study. I’m not one of those people. I need to study hard, write down the information, and review / recall it often. 2.) Exam Environment: Salesforce certification exams are taken on a computer and monitored by a proxy. The exam softw
