Chinese Database History: From Banking Systems to the Railway Ticket OLTP Challenge

The Tencent Cloud TVP series "China Database Past and Present" documents the fifty‑year development of database technology in China, featuring interviews with experts who witnessed the rise of databases from the early 1990s to the present.

1. Beginnings with Banking Deposit‑Withdrawal Systems – In the late 1980s and early 1990s, Chinese enterprises and government agencies began adopting computer systems. Banking applications such as “通存通兑” (deposit‑withdrawal) were among the first large‑scale uses, laying the groundwork for later database adoption despite limited hardware and network infrastructure.

2. A Global OLTP Challenge – the Railway Ticket System – The Chinese railway ticketing system of the 1990s became one of the world’s most demanding online transaction processing (OLTP) workloads. Handling billions of ticket requests during peak travel periods required a highly reliable, high‑throughput database solution, and the project became a flagship case for Sybase and other vendors.

3. Industry Landscape and Major Vendors – The 1990s saw the entry of international database vendors into China, including Oracle, Sybase, Microsoft SQL Server, IBM DB2, Informix, and Teradata. Each pursued distinct market strategies: Oracle leveraged strong R&D and certification programs; Sybase promoted its client/server architecture; SQL Server targeted small‑to‑medium businesses with low cost; DB2 emphasized performance for large enterprises; Informix and Teradata focused on data‑warehouse solutions.

4. Summary – The rapid growth of China’s database market in the 1990s was driven by foreign technology, large‑scale national projects (banking, tax, telecom, railway, water‑conservation), and the emerging demand for high‑performance OLTP and data‑warehouse systems. The series looks ahead to the 2000s, where internet expansion and big‑data technologies will bring new opportunities and challenges for Chinese databases.
