During the tender years of our upbringing, we observed our mothers spending hours in the realm of the kitchen cooking aromatic foods. In tandem with our mothers’ culinary mastery, we strongly admire our fathers’ role in bringing home bags of fresh vegetables, groceries enabling our mothers to create magic in the kitchen. Subsequently, I assisted my mom in arranging the delicious dishes on the dining table, ensuring that everyone was served, and took pleasure in creating an atmosphere where we all relished the delightful meal together.

The same scenario can help us to grasp the small yet noticeable distinction between Data Engineer, Data Scientist and Machine Learning Engineer showcasing how these disciplines contribute uniquely. While the father takes on the role of Data Engineer, our mother excels as a Data Scientist and me outperformed as Machine Learning Engineer. :) :)

Bringing the data into a proper and usable form comes under the father’s responsibility, while in kitchen mother adds a pinch of this and a dash of that, just like the job of a Data Scientist who enhances and refines the data. I ensured a proper serving of the food like delivering the project so that everyone can enjoy these mixed efforts. This comparison illuminates the distinct yet complementary roles that family members and data professionals play in transforming raw ingredients into valuable insights.

In technical terms,
Data Science is the discipline that deals with analyzing, interpreting, and drawing insights from vast amounts of data to make informed decisions and solve complex problems.

Skills:

  • Programming: Python/R, SQL
  • Statistics & Math: Probability, Linear Algebra, Calculus
  • Data Analysis & Visualization: Pandas, NumPy, Matplotlib, Seaborn
  • Machine Learning: Supervised & Unsupervised Learning, Deep Learning (TensorFlow, PyTorch)

In contrast, Data Engineering is the practice of developing, constructing, and managing data architecture, systems, and pipelines to ensure the efficient and reliable flow of data from various sources, facilitating data analysis and decision-making processes.

Skills:

  • Programming: Python, SQL
  • Big Data: Hadoop, Spark
  • ETL Tools: Apache Airflow
  • Cloud Platforms: AWS, GCP

Machine learning Engineering focus on taking the machine learning models developed by data scientists and making them operational in a production environment ensuring that the models can handle real-world data, scale effectively, and integrate seamlessly with software systems.

Now, your inclination towards either bringing the groceries (data engineering) or preparing the skills (data science) or delivering effectively (Machine Learning Engineer) can guide you in choosing a suitable stream in the realm of data-related professions.

Skills

  • Programming: Python
  • Machine Learning Frameworks: TensorFlow, PyTorch
  • Model Deployment: Docker, Kubernetes
  • Cloud Platforms: AWS, GCP, Azure

In this blog I detailed the invaluable contributions of various data professionals (Data Engineer, Data Analyst, Data Scientist, Machine Learning Engineer, Business Analyst) within the context of a real-time data-related project, particularly focusing on an e-commerce scenario. Each professional’s unique skills and responsibilities are highlighted to illustrate how their collaborative efforts contribute to the seamless execution of the project.

All the best for your future….
