Machine Learning: Building predictive models to make data-driven forecasts.
Data Visualization: Presenting data in a visually understandable format.
Example: In retail, Data Scientists analyze consumer purchase histories to predict trends and recommend products.
What is Software Engineering?
Software Engineering is the systematic approach to designing, developing, testing, and maintaining software applications. Software Engineers apply engineering principles to create reliable and efficient software solutions.
Core Components of Software Engineering
Software Development Life Cycle (SDLC): A structured process involving planning, design, development, testing, and maintenance of software.
Programming and Coding: Writing code to build applications.
Testing and Debugging: Ensuring the software functions as intended.
Deployment and Maintenance: Releasing software and regularly updating it to fix bugs or improve performance.
Example: In banking, Software Engineers create secure mobile apps for customers to manage their accounts.
