Oracle, as a leader in the enterprise-level database market, has long occupied a dominant position in the industry by virtue of its powerful functions, extensive market influence, and comprehensive technical support and promotion system. However, in recent years, PostgreSQL has become a highly regarded open-source database software due to its outstanding performance and flexibility. IvorySQL is developed based on PostgreSQL with added compatibility features for Oracle databases, aiming to combine the advantages of open source with enterprise-level requirements.

To promote the ecological development of IvorySQL, the IvorySQL 2025 Ecological Conference and PostgreSQL Summit was grandly held recently. This conference brought together core PostgreSQL developers worldwide, leaders of international open-source communities, and top domestic technical experts, forming a strong lineup.

During the conference, with the full support of various industry experts, the IvorySQL open-source community established the Expert Advisory Committee, aiming to learn from the successful experience of enterprise-level databases and further improve product features and ecological construction.
