This article examines the compatibility landscape of major Chinese database products, comparing their support for Oracle, MySQL, PostgreSQL and other standards, and outlines the available assessment and migration tools to help users choose the right solution for heterogeneous environments.
This article surveys the compatibility of major Chinese database products with Oracle, MySQL, PostgreSQL and other systems, covering compatibility targets, levels, assessment methods, migration tools, and specific feature support such as protocols, data types, character sets, SQL syntax, procedural languages, built‑in functions, system views, optimizer capabilities and security features.
During the early 2000s, the database industry faced Y2K-driven robustness upgrades, intensified global rivalry among Oracle, IBM, Sybase and Informix, while Chinese university‑originated systems like Kingbase and DaMeng leveraged government backing and venture capital to begin challenging foreign dominance.
This article reviews five decades of Chinese database development, from the 1980s pioneering efforts and early hardships to the rise of domestic products, market perceptions, and the recent documentary series that chronicles the industry's milestones and future challenges.
Chinese domestic database vendors have surged from 27.1% to 55.4% market share between 2018 and 2022, but this growth raises questions about technical parity, global competitiveness, branding, and the need for honest, innovation‑driven strategies to sustain long‑term success.
The article examines whether establishing national standards for Chinese domestic databases can foster industry development, weighing the risks of over‑regulation against the benefits of standardized observability, data‑dictionary, cloud‑integration, and programming interfaces, while sharing real‑world migration experiences.
The June 2020 DB-Engines ranking shows a stable top‑10 worldwide while Chinese domestic databases surge in popularity, driven by pandemic control, new‑infrastructure policies, and strong performance in cloud and financial sectors, with notable gains from openGauss, PolarDB, and OceanBase.
