Note: Scheduling and grading procedures were indicated as a problem at PCHS. AI can resolve this problem.
What's the Problem?
- Redundant Data: scheduling and grading procedure. This wastes space and if the address changes, you have to change it everywhere!
- Inconsistent Data: Maybe sometimes you write "Street" and other times "St." That's confusing!
- Difficult Updates: If you need to change a piece of information, you might miss some spots, leading to errors.
What's the Solution?
Data normalization is a process that organizes data to:
- Reduce redundancy (no repeated information).
- Ensure data consistency (everything is written the same way).
- Make it easier to update and manage data.
Think of it like this:
- Instead of writing a student's address every time, you create a separate "Addresses" table. Then, in the "Students" table, you just put a link to the correct address.
- You set rules for how information is written (e.g., always use "Street").
Why is it important?
- Saves Space: Less repeated data means you need less storage.
- Improves Accuracy: Consistent data means fewer errors.
- Makes Things Faster: Databases work more efficiently when data is organized.
- Easier to maintain: when data is normalized, it becomes much easier to update, and change information.
In simpler terms:
Data normalization is like tidying up your data so it's clean, organized, and easy to use. It helps prevent messes and makes sure everything is in its right place.
