CST363: Introduction to Database, Week 8

Briefly summarize the what you consider to be the three (3) most important things you learned in this course.

The three most important things I took away from this course were how to design databases, write SQL queries, and understand the differences between MySQL and MongoDB.

First, I learned how much thought goes into designing a database that actually works well. Things like normalization, relationships between tables, and setting up primary and foreign keys all matter for keeping data clean and organized. It made me appreciate how planning on the front end saves a lot of problems later.

Second, working with SQL taught me how powerful and precise it can be when you know what you’re doing. Writing queries to pull, join, and filter data helped me understand how everything connects behind the scenes. I feel a lot more confident using it now.

Lastly, comparing relational databases like MySQL with NoSQL systems like MongoDB showed me how different approaches work for different needs. MySQL makes sense for structured data and clear relationships, while MongoDB is great for flexibility and projects that change quickly.

Overall, this class gave me a stronger foundation in how data really works and how to choose the right tools for the job.
