A data engineer creates, assembles, tests, and maintains architectures like databases and massively parallel processing systems. On the other side, a data scientist is a person who organizes, cleans, and manipulates (huge) data. Data engineers work with unprocessed data that has an instrument, machine, and human error. Unformatted and perhaps containing system-specific codes, the data may not have been vetted and contain questionable records. Most of the time, data scientists will already have data that has undergone a preliminary round of cleaning and manipulation, which they can use to feed to sophisticated analytics software, machine learning algorithms, and statistical techniques to prepare data for use in predictive and prescriptive modeling. It goes without saying that in order to construct models, researchers must examine industry and business-related issues, and they must make use of vast amounts of data from both internal and external sources to meet business requirements. In order to discover hidden patterns, sometimes also entails researching and examining data.
