Data science is one of the “sexiest jobs,” which is considered as a buzz on the internet. Data science is a field which is continuously growing and hot right now. We’ll require lots of data scientists than there are currently available.
However, there are a wide range of various jobs and roles under the data science tree to choose from. Here is a complete list:
A data analysts job is to handle various tasks involving data wrangling, visualization, and processing of large amounts of data. They make use of data for companies to make wise business decisions and also perform queries on the databases continuously. This is because they need to modify and create algorithms that can be used to obtain information from large databases without changing the data.
SAS, R, SQL, and Python are some of the requirements for data analysis. Whereas, doing certification in the mentioned fields can improve the skills for your job applications. You need to be good at areas of problem-solving.
Data engineers are responsible for building enormous reservoirs for big data. They construct, develop, test and also maintain architectures such as large-scale data processing systems and databases. Data engineers also update the current systems with enhanced versions of the existing technologies to boost the performance of the databases.
If you are curious about knowing which skills are required to become a data engineer, here are some of those which include NoSQL, Matlab, C++, Ruby, and Hive. It would be better to work on some of the popular ETL tools and data APIs, etc.
