ACID, CAP Theorem

### Giai đoạn: Nền Tảng & Khái Niệm Cốt Lõi **ACID, CAP Theorem** ACID describes the guarantees a database transaction provides: atomicity, consistency, isolation, and durability, ensuring reliable operations even under failure. The CAP theorem states that a distributed system can only guarantee two of three properties at once: consistency, availability, and partition tolerance. Architects use both concepts to reason about the trade offs involved in choosing databases and designing distributed systems. ### Khái niệm cốt lõi: 1. **Nắm vững khái niệm cơ bản** 2. **Áp dụng vào kiến trúc thực tế** 3. **Tối ưu hóa và kiểm thử** ### Tài liệu tham khảo chính thống: - [What is CAP Theorem?](https://www.bmc.com/blogs/cap-theorem/) (article) - [CAP Theorem - Wikipedia](https://en.wikipedia.org/wiki/CAP_theorem) (article) - [An Illustrated Proof of the CAP Theorem](https://mwhittaker.github.io/blog/an_illustrated_proof_of_the_cap_theorem/) (article)
