Gaining coding experience in a single programming language might not be of good help with newer job roles that are coming up in the competitive market.

Skill #3: Data Warehousing
Expertise in a relational and non-relational database system is crucial for a big data analyst. You must be skilled in relational databases like Oracle, DB2, and MySQL. The non-relational database includes NoSQL, Cassandra, HBase, and Redis.
Skill #4: Multiple Technologies
Programming is no doubt an essential skill that a data analyst needs to learn. Besides this, having skills in multiple technologies will help you prosper in your big data career.
Technologies are not at all limited to programming. There are a wide range of technologies a data analyst professional needs to be familiar with – from hardware to software tools. For instance, SQL, R, MATLAB, SPSS, Cognos are equally important as Python, R, and Java.
However, technologies will vary based on the environment, company, and the kind of project you’ll be working upon.
The more technologies you’re familiar with more credible you will be.
Skill #5: Computational Frameworks
Exceptional understanding in computational frameworks such as Apache Storm, Apache Samza, Apache Spark, MapReduce, and Hadoop is essential for a big data analyst. These technologies come in use during big data processing.
Skill #6: Understanding Business
The big data and analytics field is useless if it cannot be applied to a business setting. Data analysts should have a broad understanding of the business and the domain they’re working in. Expert professionals in this field have the expertise of identifying business opportunities and threats if any.
Domain expertise gives them the advantage to deal with stakeholders and other business leaders.
Becoming a big data analyst requires mastery of the skills mentioned above. If you’re looking for a way to stay at the competitive edge, data analyst certification is a great option to start with.
Industries are buzzing about big data, earning a credible certification today simply means better job opportunities and a future proof career.
