PYTHON | SESSION 3 - Part 1 | JOINING, RELATIONSHIP AND DATA MODELING

Master Python data model designing and joining relationships, a critical skill for data scientists and DBMS developers to structure and massage data before modeling. This tutorial covers vertical joins (appending) and horizontal joins (merging), providing a hands-on guide to using the Pandas concat function across multiple real-world scenarios. Learn to resolve complex issues such as mismatched column names through renaming, handling different field counts that result in NaN values, and managing data type mismatches that convert numeric fields to object strings. We also demonstrate advanced techniques for appending multiple datasets simultaneously and removing duplicates to ensure a unique, clean final output. By the end of this session, you will be able to perform sophisticated data massaging and design robust data models for any industrial application. Stop fearing the future. Start building it.
