Data engineering vs Data Science


Data science vs. data engineering is an age old debate. Both of these are separate software engineering fields, even if data as a whole is a vast field. Among the most important things in data engineering is large data optimization. Big data refers to the procedures used to manage very complicated or huge collections of data. It is a subset of data engineering.


But according to research conducted in 2017 by the technology-focused firm Gartner, between 60% and 85% of big data projects fail.  The main cause of this is untrustworthy data structures. Good data engineering is more crucial than ever in light of the impending digital revolution that many modern businesses see as inevitable. 


Regretfully, there was little knowledge of data engineering in the early days of big data management. Consequently, the role of data engineers was assumed by data science teams. But it wasn’t quite effective. This is so because the majority of what data scientists are trained in is exploratory data analysis. 


Interpreting data is the responsibility of data scientists. The initial step of modeling data for interpretation is not well understood by data scientists. However, in order to accurately assess an analytics database, they make use of mathematical, statistical, and even machine learning techniques. Data engineers ensure that this data is initially prepared for data science teams. Data engineers are therefore designed to evaluate the quality of data. 


They then purify the data to improve the quality when it isn’t up to grade. It is for this reason that a large portion of the work involves database design. It should be noted that machine learning engineers are capable of performing data scientist and data engineer duties. Sometimes advanced data engineers take on the responsibilities of machine learning engineers.
