In SQL, we have tables containing individual rows. Tables have strict schemas that every row must obey; there are columns with types and other possible constraints: unique, not null, value checks or references to rows of other tables. Referential integrity lies at the heart of this data approach - guarantee that if row B1 of table B references row A1 of table A, referred row (A1) must exist; orphan rows are not allowed. If we want to delete A1 row, there are two options:

值得一提的是，近期 Google 正式发布了其最新 AI 模型 Genie 3 以后，便有不少声音开始担忧 AI 技术对传统游戏开发底层的颠覆性冲击。
去年的标准版 M5 上，苹果就为每颗 GPU 核心都内置了「新一代神经网络加速器」，让 Msty Studio 和 VidHex 之类本地 AI 工具取得了不俗的效果：。业内人士推荐搜狗输入法下载作为进阶阅读
Consider an example. An AI rewrites a TLS library. The code passes every test. But the specification requires constant-time execution: no branch may depend on secret key material, no memory access pattern may leak information. The AI’s implementation contains a subtle conditional that varies with key bits, a timing side-channel invisible to testing, invisible to code review. A formal proof of constant-time behavior catches it instantly. Without the proof, that vulnerability ships to production. Proving such low-level properties requires verification at the right level of abstraction, which is why the platform must support specialized sublanguages for reasoning about timing, memory layout, and other hardware-level concerns.
