What Is Big Data?
Big data refers to a complex set of data from numerous sources. The traditional data processing methods are no longer recommended to process them. In the first place, these traditional methods might not even be powerful enough to come up with adequate results.
Oracle further defines big data as having these three qualities:
- Volume. Big data entails having high volumes of unstructured data to process, as seen with Twitter data and website clicks.
- Velocity. This refers to the rate at which we receive data. Some data, such as post engagement on social media, are generated in real-time.
- Variety. Big data is a collection of unstructured and varied types of data. A data set, for instance, may include different types such as text, audio, video, and more.
What Jobs Use Big Data?
So many disciplines use big data technologies especially those that use large amounts of data daily. Artificial intelligence, for instance, uses big data because of the massive calculations that it needs to prove theories and conduct experiments. Retail industries also use big data for predictive analytics, which helps them understand and respond to consumer needs.
Jobs related to computer and information research earn an average of $122,840 per year, according to the US Bureau of Labor Statistics. The job outlook is even better at a foreseeable 15 percent rise in the next decade. This is much faster than the average growth rate across all occupations.
Nowadays, various jobs use big data skills, such as:
- Big Data Engineer. These professionals are responsible for managing the big data archives of the company. This means expertly yielding results out of huge amounts of data. Computing knowledge is a must for data processing and analysis.
- Data Architect. A data architect develops the database resources of the company. Part of his/her job includes ensuring that a solid information system is in place. This is important for big corporations with lots of data coming in every day.
- Database Manager. With the massive volume of unstructured big data coming their way, database managers develop applications to organize these data. They maintain order by establishing standards and controls and troubleshooting when necessary.
- Business Intelligence Analyst. With the rivers of data collected daily, analysts lead the careful selection of relevant data. They are the ones who review and validate these data to ensure that a correct analysis will be drawn from them.
- Data Scientist. A data scientist collects and interprets data, after which s/he recommends an actionable insight to relevant stakeholders. Such insights help a company formulate plans for improvement. Programming skills help process these big data.
Steps to Learn Big Data
It takes a serious commitment to study and learn big data. This does not simply involve collecting data and figuring out what to do with them. You need to have certain skills related to data science and machine learning to really excel at it.
Below are some steps that you can consider learning big data. The steps you will take will depend on whether you have already learned how to become a data analyst or not.
Step 1: Live With Data Daily
Venturing into big data analytics means living with data daily. Doing so will help you gain insights into whatever information your company needs. It means having various sources of data to examine and select from every day.
Make sure to only read analyses from reliable sources. This will help you see techniques and strategies that can help you in presenting accurate data. Remember that maintaining credibility in your work is important when utilizing big data.
Step 2: Decide Which Software to Master
Big data software programs and tools are necessary to ensure correct data processing. You are not obliged to learn how to use all of these software programs, but knowing more enhances your versatility. The software programs either come for free or with a fee.
These programs use computing scripts like Java, HTML, and more. If you want to be an expert on these tools, a background in programming is essential. Choosing to master specific software is enough of a first step to learning big data.
Step 3: Take on Personal Projects
Taking on personal projects will help you understand big data on a practical level. You learn to apply these on different topics and discussions. You also get to hone your skills in processing data and extracting analyses from them.
Personal projects may include commissioned ones from students who need research assistance. You can also opt to work on your own if you’re aiming to get an article published in a journal.
Step 4: Learn How to Extract and Communicate Insights
Big data is meaningless if it can’t be read or understood. Visual storytelling plays a huge part in communicating your findings from datasets. Not all executives in a company can keep up with the jargon of big data.
So, make sure that your target audience understands your insights. Visual aids, such as graphs and bars, and analysis tools such as data flows can help you achieve this.
