I'm getting a lot of questions from audiences about Big Data - what is it? Hadoop - what is this? and more importantly why do i need to understand this now? will it be needed for my organization?. Bottom line is that the user community is completely befuddled with the whole Big Data and Hadoop messages. Let us take a step back and clear the slate.

What is Big Data? in a true sense, data that has been used to make decisions with respect to your business - transactional, spreadsheets, emails, campaigns, sales-force, call center, competitive intelligence, analytics, legal contracts, manuals, web data, consumer forums, content management systems and more form the foundation for Big Data. Another dimension to view this is data that lies outside of transactional and EDW systems, that influence your business decisions and provide you insights into the consumer and product behavior is also called Big Data, as it has no defined structure or storage mechanism. Big Data is big in terms of size, volume and complexity independent of Time.

Now let us come to Hadoop, it is a software solution framework, distributed by Apache foundation. The architecture of Hadoop lends to distributed and parallel computing techniques, by which you can manage massive volumes of data and process it to harness the underlying value in a relatively manageable time. Hadoop is an ecosystem as it is a community developed project and has continued contributions from the community of developers.

Is Big Data worth pursuing for any organization? very much yes. But like any other solution you need a strong business case to implement this type of program. You need a very strong governance model to analyze the type of data you want and what business value will it bring to the organization. It is a maturity journey, and it is not a turnkey solution to switch on a technology from any vendor and declare victory.

Do I need to use Hadoop and learn everything it has as a framework? well if you have to yet start the Big Data journey, all RDBMS and DW Appliance vendors are working on a race against time to bring Hadoop integration via your favorite DB platform. But even after that integration is complete from the given vendor, you still need to understand how Hadoop works and what type of problems will it solve, you will need to understand TextualETL and how you can write business rules in English to process text data of any type and much more. But the silver lining in this cloud of complexity is, all these technologies are evolving and will mature by the time you are ready to adopt them. They are all GUI driven and self managing, they all address problems that your current RDBMS or EDW platforms cannot resolve.

Two words of advise, Learn everything you can about these topics, sort out Blather and Real Information on these topics.

Remember not every business is Facebook or Twitter or FourSquare, but every business will evolve in the future to adopt similar models to emerge Customer Centric. As you start this journey, remember it is a Continuum and has multiple stages of maturity.
