They analyze data, create documentation, and serve as a communication bridge between business and technical teams. Business Analysts evaluate solutions, manage projects, and focus on continuous improvement to enhance organizational efficiency and meet business objectives.As for the difference between a Business Analyst, and a Data Analyst, the Business Analyst focuses on improving overall business processes and strategies, utilizing data analysis as part of their toolkit. On the other hand, a Data Analyst concentrates on working directly with data to extract insights that inform specific decisions within an organization. While there may be some overlap, the primary emphasis and objectives of these roles differ.
  • Tools Business Analyst Use: Microsoft Excel, Microsoft Power BI, Tableau, Qlik
  • Languages Business Analyst Use: SQL, Python (basic)

 

5. Data Scientist:

  • Responsibilities and Scope:   A Data Scientist uses statistical, mathematical, and programming skills to extract insights from data. They define objectives, collect and clean data, conduct exploratory analysis, and apply statistical modelling and machine learning.The roles of Data Scientist and Data Analyst share similarities but differ in their primary focus, depth of analysis, and overall objectives. In essence, while both roles involve working with data, a Data Scientist typically deals with more complex analyses, machine learning, and predictive modeling to uncover deeper insights, whereas a Data Analyst focuses on extracting actionable information from data to support day-to-day decision-making in a more targeted and specific manner.
  • Tools Data Scientist Use: Jupyter Notebook, TensorFlow, Scikit-learn, Databricks
  • Languages Data Scientist Use: Python, R, SQL

6. Machine Learning Engineer:

  • Responsibilities and Scope: A Machine Learning Engineer specializes in developing and deploying machine learning models to address business problems. Responsibilities include defining problems, collecting and preprocessing data, engineering features, selecting and optimizing algorithms, and validating model performance. They deploy models into production, ensuring scalability and collaborating with cross-functional teams.While Machine Learning Engineers (MLEs) and Data Scientists (DSs) share some similarities, they differ in their primary focus, objectives, and skill sets. In essence, MLEs are more engineering-focused, with a goal of deploying machine learning models at scale, while DSs have a broader focus on exploring data, generating insights, and informing strategic decisions within an organization.
  • Tools used by Machine Learning Engineers: TensorFlow, PyTorch, Keras, Databricks
  • Languages used by Machine Learning Engineers: Python, Java, C++

7. Data Product Manager:
