At present, organizations are hunting for data as well as data experts to analyze the market requirements, explore the meaningful insights, predict the behavior and making careful decisions from data. Data Engineers and Data Scientists work as a team, who transform the raw data in ways that provides their organization with a competitive edge. But the data engineers and scientists have different roles and responsibilities, academic background, key skills and pay scales.
Now, if we compare Data Engineer vs. Data Scientist, we need to consider the following points:
- Roles and Responsibilities
- Academic Background
- Technical Skills
- Jobs Prospects and Salary Trends
- Top Recruiters
Roles and Responsibilities
A Data Engineer is involved in different tasks such as data preparing and processing, model development; generate tests to validate & maintaining the complete architecture. They focus on creating a full-stack for data collection, storage, processing in real-time or in batches. They usually employ software tools and programming languages to build API’s for processing of data from real-time and large databases.
A Data Scientist is involved in data pre-processing, hidden pattern finding, organizing the large datasets to answer the business queries, analyzes and interpret complex data. Besides this, Data Scientists perform descriptive statistics and automate the model accordingly to fulfill the organizational and customer need. They also utilize artificial intelligence and machine learning models for better prediction, classification, and clustering.
|Data Engineer||Data Scientist|
|To explore data acquisition opportunities.||To develop reliable operational models.|
|To develop, deploy, test & maintain data architectures for real and large systems.||Conduct research to answer the organization and business queries.|
|Use different Software tools and scripting languages to combine systems together.||To find out the hidden pattern from huge data.|
|Explore new approaches for data acquisition, and build new applications for existing data.||Carry out data analytics and optimization using Artificial intelligence & machine learning.|
|To build pipelines for different ETL operations.||Deployment of more sophisticated analytics programs, and executing machine learning, and statistical methods.|
|Monitoring data collection, storage, as well as data retrieval process.||Performs descriptive statistics and automate the model accordingly.|
|Ensures data accuracy and flexibility.||To make a bridge between the stakeholders and customer.|
Data Engineers are required to be a graduate in Computer Science concepts with a strong academic and analytical background. Data Scientists are supposed to be a graduate in engineering sciences viz. computer, social, and physical along with good control over statistics. However the people with higher educational background like M.Tech or Ph.D are preferred at higher levels in industry. Apart from these basic academic qualifications, certifications in the area of Data Science give strength to the candidate profile.
A Data Scientist’s skills are more analytics oriented in comparison to Data Engineer. Data Scientist should have a strong Statistics and Mathematics background. The desired programming languages are R Programming, MATLAB, SAS, Python programming, Julia, SCALA and so on. They should have strong hands-on Hadoop based analytics, Statistical analysis, data mining and Machine Learning approaches.
