A data engineer is the one who designs the platform and the structure which gathers and stores all the data from the users such as what item they are buying from an online store and what are the contents of their cart currently as well as on their list. Data engineers ensure that all the data are stored efficiently and are easily retrievable.

Data engineers are adept at working with a range of sources and framing ETL queries to collect data from them quickly. They then organise all the data in databases for the companies and individuals or others to use it from there.
You will need to acquire knowledge of various languages such as Java, Python, C++, SQL, Hadoop, Spark, Ruby, etc. on top of data analytics certification. It should be noted however that there is no need to learn all these languages as the requirement varies from company-to-company.
Being a data engineer provides you with the rare opportunity to work as both a software engineer and a data analyst.

Data Analyst

There is direct involvement of data analysts in everyday business activities. A data analyst or business analyst is expected to perform a significant amount of ad hoc analysis every day.

A good understanding of business, statistics and data manipulation is thus required in a data analyst.

Data Scientist
