changed the title

I just pushed it because I had already started locally but will not be working on it now. |
- moved nosql, m2m relations and aggregate functions to week 2
… with sqlite - made focus on creating a DB (provided) - CRUD SQL - working with relations - adding new columns and tables
…o the point - add vscode extension - fixed link to json file
- include venn diagrams of sql joins
…syntax on examples
|
Locally, prettier is fine, but it's complaining on CI. |
| ## EXERCISE 4: Design and implement a database for existing data | ||
|
|
||
| Design an ER model and implement the respective database for the data in [this file](session-materials/articles_example.json). | ||
|
|
||
| Remember: | ||
|
|
||
| - Don't worry if you can't do every step perfectly. | ||
| - The important thing is to understand the main ideas. | ||
| - Take your time and ask questions if you're confused. | ||
|
|
||
| ### Steps | ||
|
|
||
| 1. Analyze the JSON structure | ||
| 2. Identify entities and relationships | ||
| 3. Create an ERD | ||
| 4. Translate to CREATE TABLE statements | ||
| 5. Insert sample data | ||
| 6. Write queries to retrieve information |

If there's not enough time for this exercise or it's too much for this class, this could be used as an assignment for week 2.
They did that for week2/3 the last time

I had to run npm install again, and that fixed it for me. Let me know if that doesn't help. |

Make explicit how the session should be organised e.g. what the mentor should run on their machine/screen, and what the trainees will do on their own machine.
