big data basics and courses

Welcome to the Big World of Data

The recent fad in IT is ‘Big Data’. It is famous and commands money & respect, so everyone wants to be ‘in’ it in the IT world. But to those who are not yet engulfed by this trend, this gives a primer to what it is in basic terms.

Lets start with the scenario

For a large global company, the data generated by its systems is unbelievably massive – from tens of Terabytes to Petabytes. It could be detailed sales data, transactions, instrument readings, website access & usage, customers, social media, search engine data etc.

The systems at the company keep accumulating more and more data over time. Over a period, it starts becoming huge, and keeps growing bigger and bigger and massive. The data could come in torrents and in disparate formats like text, images and videos, not just structured RDBMS type data.

This information is valuable. Companies need to analyse this data to understand their performance and make ‘learned’ strategic decisions for future.

If they ignore, their strategy becomes skewed, ‘base-less’ (because it is not based on data research), and hence risky. They can ignore this only at the cost of loosing out to competition. And this is a continuous process because they need to keep making course corrections at regular intervals to align with the actual performance(vs expected) and market movements.

Traditional Methods

But traditional technologies and database servers cannot handle and process such data with respect to the combination of huge size, great variety and high speed.

So Big Data technologies bring in capabilities to

  • Take-in massive amounts of disparate data at high speed
  • Hold in a distributed environment (distributed storage)
  • Process it by horizontally distributing the load across clusters (distributed processing) and,
  • Be continuously scalable (scale-out), available anytime (least downtime), robust, responsive, affordable and secure.

Traditional ‘scaling-up’ means adding more resources (memory, storage, processing) to a single node in a system, to which there are obvious limitations.

‘Scaling-out’ means to add more nodes, like adding more servers and distribute storage and processing. The advantage is that logically, it can be expanded to a limitless extent.

Big Data Solutions

Hadoop is one such Big Data solution. It is an Apache open source framework written in java. Hadoop is designed to scale up from a single server to thousands of machines, each offering local computation and storage.

Opportunities

Big Data has its own challenges and complexities, so it may not be suited unless the requirements have reached or are expected to reach those proportions of size, variety and speed.

The transition from the Enterprise Data Warehouse centric architecture to the Big Data Management System – on Premise, on the Cloud, or in hybrid Cloud systems – is going to revolutionise any company’s information management architecture.

The demand for Big Data professionals is rising significantly. To learn Hadoop and become a developer, knowledge of Java basics is crucial. Plus knowledge of basic Linux is helpful. Existing System Administrators, DBAs, BI/DW analysts, ETL architects etc have a good scope to move their career path.

why does everyone need continuous training ?

 What is continuous learning

We need to consciously identify areas to improve our hard skills (related to the technical and functional aspect of work we do) and soft skills (behavior, personality, communication, responding to scenarios, social integration, problem solving, managerial etc), and work constantly towards improving our skills and knowledge in such areas. There is no end to it. There is no point where we can claim that this level of knowledge, skill and capability is enough.

We need to keep sharpening our saw all the time. Continuous learning of new technologies or skills is the only solution for a long, growing and successful career. Remember that a rolling stone gathers no moss.

This applies not just to students and professionals, but to each and every one in every imaginable field. The most successful people are the ones who are most agile and nimble when it comes to applying themselves to handle any type of change and challenge. Know more about what training you an choose to take up.

improve knowledge

The knowledge that we gain in our education system is hardly sufficient to excel in our jobs. Most of us rarely find a direct correlation between our study and work.

That means what we have studied during our education years does not convert into delivering quality work output.

Globally, industry leaders have complained about lack of direct employability in our university graduates.  Not only in terms of the technical knowledge and skills, but also in terms of the right personality, professional behaviors, presentation and communications skills needed. They see a need to invest heavily in training before putting people on the job.

Importance of Continuous Learning & Training

Continuous Learning & Training tends to bridge this gap and puts us ahead of competition, given that our uncontrolled population growth only adds to uncontrolled competition. Organisations which are learning oriented and continuously make investments in training (Corporate Training) have seen considerable improvement in productivity and reduction in overall costs.

Some of the world’s best sportsmen have sustained such long careers because they never stopped training and learning new techniques, as hard as when they started their careers.

Including superstars like Sachin. The day they think they don’t need to learn anymore, they cannot sustain success. Similar is the need in all professions through it does not show up so apparently to people around.

Don’t be a “somebody” – stand out from the crowd

We have seen many people just go to work and do it very mechanically, doing the same thing in the same way everyday, just waiting to go home. But if you are choosing to be among the ones who want to grow to the peaks of your career and differentiate yourself through fair means, then learning new jobs, skills and techniques is mandatory.

If time is a shortage, pick the range of online and elearning courses available these days in several fields.

Start today – learn a better skill

Start this endeavour by proactively finding the right Mentors, Tutors or trainers or coaches. A mentor is a senior & respected person who can help you identify your shortcomings, your goals and choose the best career options. They usually do not impart training. Tutors, Trainers and coaches actually help you improve on the skill that you want to gain.

Plant the seeds for a better life and career through by enhancing your knowledge and skills, and be ready for better opportunities.

training courses for a better career

When, what, where and how of learning

Once we decide we want to take up training to build or enhance our career, we are also beset with a question around what to learn, and in what sequence. A student coming fresh out of college faces an uphill task of trying to figure out what is the hottest and quickest skill to learn to enhance chances of a good job. For a working professional, it is about switching career or trying to grow at work.

what to learn, when, where and how to learn for career path

Select the right skills to learn for a top career

Nothing wrong in this. After all, everyone wants to earn and grow and build a successful career. But to avoid a waste of time and money, you should take prudent decisions about learning choices. There are many who take a course after course as they fail to get a job each time. To choose the right training, your education background, the marketability of the skill, your analytical skills and your attitude are key.

positive attitude

Take the course that compliments your strengths. Be honest about your analytical skills, comprehension skills, communication skills, and your attitude towards working in teams.

Formal Studies – as long as you can

Also, before going ahead to take a plunge into training and looking for a job, study university education as much as you can. You don’t want to repent later in our life that we should have gone for Masters or higher degree when you were young and sharp at mind.

A career in Entrepreneurship

If you have an excellent idea for an industry, do also consider training in the technical areas that can help enrich and implement the idea. These days, it is worth trying to setup a startup with low capital and pursue, if it clicks, nothing like it. It doesn’t matter much whether you are young or old, except in terms of maturity in handling money & people around.

poor education results in poor skills

Opportunities and challenges

The recent and emerging industries like IT, Finance, Banks, eCommerce, Internet based ones  etc are the ones which give the best opportunity for an early job, that too at the top cities. These careers also give better paychecks and flexibility. Of course, working hours are more and stress levels are high. And job security, don’t ask!

The more the competition and money, the more the stress – basic principle. It is like equity vs bonds. The other industries like manufacturing have a more even and consistent sort of intake and life with less of ups and downs. Jobs in Government & PSU sectors have increasing competition year on year. The high end civil services careers are still much sought after by the cream of students. The spikes and troughs in the emerging industries are inciting a significant lot of students to prefer Government, PSU, Civils  etc jobs back again.

work smart not just hard

Getting to work in the intended industries most often needs you to do a lot of unlearn and learn. And the farther you are with respect to your background, the more learning effort you have to put to close the skill gap to avoid being frustrated later. For e.g. you would find people from every branch of engineering and other degrees in IT-Software jobs, although unrelated to their field of study. Industry experts also want to join as Business Analysts into IT. If you like travel, have a skill of easily getting along with people and being able to convince them, a marketing career is a good option.

Learn-From-Our-Mistakes

Continuous learning and skill development

Hence there is no doubt continuous learning and re-skilling is necessary for a long and successful career. Right Training in the right mode solves the problem. One important point here- If you need knowledge about a new skill from scratch, don’t just get plainly swayed by the brand of the training provider. Rather pick the one where the trainer is approachable, understands your strengths and weaknesses and teaches to a limited size class, as in the earlier article about different modes of learning. Otherwise you are lost out and end up without any benefit. Like this…

uninterested class

Importance of Soft Skills

But one set of skills that are necessary for success in all corporate jobs but ignored commonly are soft skills like good communication, articulation and presentation!!! And most of us Indians are naturally low in them because of the style of our education, which focuses only on maths and science at schools or the core subject at college. Soft skills are unfortunately left out. This leaves us with less armory as compared to others who are good at these globally. You feel like you are attacked with guns while you are only equipped with spears and arrows. Our education is like in this cartoon.

our education system

When you grow higher and higher up in the ladder, these skills become more and more important. At the lowest level, it is about 80% of technical and 20% soft skills. But it just reverses at the highest levels. So don’t complain if you are not able to grow in your jobs. One key reason could be that you underestimated these strengths that you were supposed to have!!!

Conclusion

Hope this guides you into identifying areas that you need to up-skill. Further, get inputs and guidance from experts, not just by randomly asking people around you. The Counslr Career Guidance System at www.AddMyLearning.com is one such tool to get good quality guidance from people who are really knowledgeable.
