Pull request overview
This PR enhances the database documentation in taichi112.works by adding structured visual learning aids (tables, Mermaid diagrams, and cross-page “Knowledge Links”) to turn isolated concept pages into a connected learning path.
Changes:
- Replaced several bulleted concept sections with concise summary tables for faster scanning.
- Added Mermaid diagrams (ERD + flowcharts) to visually reinforce schema, reliability, and performance concepts.
- Introduced cross-links and a “Project Tracker” scenario + knowledge map to connect concepts across modules.

| | **Entity / Table** | A real-world object you need to store. | `User`, `Project` | | ||
| | **Row** | A single distinct record. | "Alice's User Profile" | |
| A user wants to track projects and the tasks within them. As we build this, we encounter every major database concept: | ||
| - We identify the core objects we need to store (User, Project, Task). | ||
| - We design how they connect (a User owns Projects, a Project contains Tasks). | ||
| - We enforce rules (Tasks must have titles, Projects belong to a valid User). |

| Reliable relational databases (like PostgreSQL) guarantee **ACID** properties: | ||
| - **Atomicity**: An operation (transaction) is "all or nothing." If a user buys an item, money is deducted AND the inventory drops. If one fails, both fail. | ||
| - **Consistency**: The database only moves from one valid state to another valid state, enforcing all constraints. | ||
| - **Isolation**: Concurrent transactions don't interfere with each other. | ||
| - **Durability**: Once data is saved, it remains saved, even if the power goes out immediately after. | ||
| This ensures that database transactions are processed reliably. |
