In this video, we cover Grade 11 ICT Unit 3.3.5, focusing on Selecting Data from Multiple Tables.
A real database rarely stores everything in one place; data is split into different tables. This lesson teaches you how to bring that data back together using Queries.
We explain in Amharic how to use Relationships to link tables and view combined information.
Topics Covered in this Lesson:
Why use Multiple Tables? (Understanding Relational Databases).
Prerequisites: Ensuring tables have Relationships (Primary Key vs. Foreign Key).
The Design View: Adding more than one table to the query grid.
The Join Line: Verifying that tables are connected correctly.
Selecting Fields: Picking specific columns from Table A and Table B.
Running the Query: Viewing the merged result.
This is a key skill for understanding how professional databases work!
