The Untold History of China's Database Industry: 50 Years of Struggle, Innovation, and Consistency

"Database Past Stories" is a fictional yet historically anchored saga that follows a generation of Chinese engineers as they confront foreign technology embargoes, build indigenous database systems, and ultimately redefine the meaning of consistency in software architecture.

Background : In the 1990s the Chinese database market was dominated by overseas giants, with enterprise licenses costing millions and priced per CPU core. Lacking bargaining power, local firms were forced to “build on someone else’s foundation.” The narrative begins with a basement in 1999 where Lin Yuru (宇睿) writes the first line of domestic database code, setting off a thirty‑year struggle against ever‑lengthening U.S. export control lists and the 301 investigation.

Key Figures and Their Roles :

Lin Yuru – The protagonist who studies at Berkeley, contributes to PostgreSQL under Stonebraker, returns to China, and later writes the "Consistency and Concurrency" monograph, advocating that database value lies in determinism rather than speed.

Chen Yifei – A prolific author of database kernel textbooks, whose "15‑day reboot" incident exposed hidden long‑running defects.

Wan Gang – Leader of SkyDB, which achieved the world‑first TPC‑C record in 2025, turning the industry’s spotlight onto Chinese databases.

Jiang Shen – A security official who manipulates policy frameworks, illustrating how political power can dictate technical outcomes.

Chen Qiming – An academic who links database research to national data‑sovereignty policy, presenting four strategic fronts: core system replacement, open‑source export, AI‑driven redesign, and theoretical innovation.

Four Volumes Structure :

Volume 1 – Early underground development (1990s) and the first choice to write code independently of foreign foundations.

Volume 2 – The “battlefield” era, covering quality crises at Huasheng, the TPC‑C world record, the 301 investigation series, and the "code has nationality" emails that forced engineers to confront geopolitics.

Volume 3 – The “road” phase, where Yuru joins BitQuiet, sees the absurdity of large‑scale commercial databases, and witnesses the rise of multi‑modal fusion at Shushun Technology.

Volume 4 – The final synthesis, presenting four core propositions: dignity, framework, determinism, and critical thinking.

Four Core Propositions :

Dignity – A single line of Chinese‑written database code can be worth a nation’s thirty‑year gamble.

Framework – The same code behaves differently under government‑funded versus market‑driven frameworks; quality and execution are merely "attachments".

Determinism – The ultimate value of a database is not performance but the guarantee that data will not lie when systems fail.

Critical Thinking – Consistency evolves from a technical protocol to a philosophical question about human and societal alignment.

The story repeatedly emphasizes that consistency is both an architectural constraint and a bridge between the physical world (what is) and the logical world (what should be). It shows how engineers turned abstract consistency concepts into concrete frameworks, influencing national policy discussions in Zhongnanhai.

Stylistically, the novel uses a three‑act structure for each chapter, inserts cliff‑hanger hooks every 800–1000 words, and weaves recurring imagery (rain, wind, roots, chairs) to bind the four decades into a single breathing narrative. Multiple points of view intersect: Jiang Shen at the negotiation table, Dong Hao in the basement, and Yuru in the lab, allowing readers to see the hidden “cards” of each stakeholder.

In the concluding section, the author argues that the future of Chinese databases will depend not on chasing speed records but on pursuing uncharted theoretical paths, echoing the mantra “write the code well first, everything else later.”
