(Hurwitz et al) Data Mining for Big Data. Data mining involves exploring and analyzing large amounts of data to find patterns for big data. The techniques came out of the fields of statistics and artificial intelligence (AI), with a bit of database management thrown into the mix. Generally, the goal of the data mining is either classification or prediction. In classification, the idea is to sort data into groups. For example, a marketer might be interested in the characteristics of those who responded versus who didn’t respond to a promotion.
These are two classes. Typical algorithms used in data mining include the following: Classification trees: A popular data-mining technique that is used to classify a dependent categorical variable based on measurements of one or more predictor variables. Here's a classification tree example. Of course, you can find many more attributes than this.

Growth of and Digitization of Global Information Storage Capacity Source Big data is a broad term for data sets so large or complex that traditional data processing applications are inadequate. Challenges include analysis, capture, curation, search, sharing, storage, transfer, visualization, and information privacy.
The term often refers simply to the use of predictive analytics or other certain advanced methods to extract value from data, and seldom to a particular size of data set. Analysis of data sets can find new correlations, to "spot business trends, prevent diseases, combat crime and so on. Work with big data is necessarily uncommon; most analysis is of "PC size" data, on a desktop PC or notebook[11] that can handle the available data set.

Big Data Hot on the heels of Web 2.0 and cloud computing , Big Data may well be the Next Big Thing in the IT world.
Whereas Web 2.0 links people and things online, and cloud computing is about the transition to an online computing infrastructure, Big Data generates value from the storage and processing of very large quantities of digital information that cannot be analyzed with traditional computing techniques. By the end of 2015, Cisco estimate that global Internet traffic will reach 4.8 zettabytes a year . That's 4.8 billion terabytes, and signals both the Big Data challenge and the Big Data opportunity on the horizon. This page provides an overview of Big Data characteristics, technologies and opportunities. The quantity of computer data being generated on Planet Earth is growing exponentially for a number of related reasons. Volume is Big Data's greatest challenge and as well as its greatest opportunity. Big data velocity also raises a number of key issues. Investopedia - Big Data Definition. ☝️ BD Dummies.

The reams of data available to companies are only as useful as the people working with them. By Ethan Rouen, contributor FORTUNE -- "Oh, people can come up with statistics to prove anything. Fourteen percent of people know that.
" – Homer Simpson The era of big data is here, the nerds proclaim. Computers are powerful enough to gather and synthesize terabytes of information to answer questions ranging from how best to compensate employees to how risky is that mortgage-backed security. But while the numbers don't lie, how people use them is extremely subjective. "Making the decision at the end of the day can be aided by data, but the thought that computers will make all the important decisions is just not true," says Shvetank Shah, executive director of the Corporate Executive Board (CEB), which recently published a study titled Overcoming the Insight Deficit: Big Judgment in an Era of Big Data.

Big data means the amount of data you’re working with today will look trivial within five years.Huge amounts of data will be kept longer and have way more value than today’s archived data.Business people will covet a new breed of alpha geeks. You will need new skills around data science, new types of programming, more math and statistics skills and data hackers…lots of data hackers.You are going to have to develop new techniques to access, secure, move, analyze, process, visualize and enhance data; in near real time.You will be minimizing data movement wherever possible by moving function to the data instead of data to function.
You will be leveraging or inventing specialized capabilities to do certain types of processing- e.g. early recognition of images or content types – so you can do some processing close to the head.The cloud will become the compute and storage platform for big data which will be populated by mobile devices and social networks.

Interpreting the Data: Parallel Analysis with Sawzall Rob Pike, Sean Dorward, Robert Griesemer, Sean Quinlan Abstract Very large data sets often have a flat but regular structure and span multiple disks and machines. Examples include telephone call records, network logs, and web document repositories.
These large data sets are not amenable to study using traditional database techniques, if only because they can be too large to fit in a single relational database. We present a system for automating such analyses. Published in:Scientific Programming Journal Special Issue on Grids and Worldwide Computing Programming Models and Infrastructure 13:4, pp. 227-298.

For fast, interactive Hadoop queries, Drill may be the answer — Cloud Computing News. Kafka. Prior releases: 0.7.x, 0.8.0. 1. Getting Started 1.1 Introduction Kafka is a distributed, partitioned, replicated commit log service. It provides the functionality of a messaging system, but with a unique design. What does all that mean? First let's review some basic messaging terminology: Kafka maintains feeds of messages in categories called topics. Communication between the clients and the servers is done with a simple, high-performance, language agnostic TCP protocol.
Topics and Logs Let's first dive into the high-level abstraction Kafka provides—the topic. A topic is a category or feed name to which messages are published. Each partition is an ordered, immutable sequence of messages that is continually appended to—a commit log. The Kafka cluster retains all published messages—whether or not they have been consumed—for a configurable period of time.
In fact the only metadata retained on a per-consumer basis is the position of the consumer in in the log, called the "offset". Distribution. Storm, distributed and fault-tolerant realtime computation. BigQuery - Google BigQuery.
