1. What is the Halo Database​

The Halo database is a database product meticulously crafted through independent research and development, leveraging world-leading database technologies combined with practical experience from core production business systems. The Halo database features advanced multi-model database technology and is highly compatible with multiple mainstream databases, thereby greatly reducing system migration costs and risks. Actual production system practice shows that it can reduce code modifications by at least 95%. At the same time, the Halo database is 100% compatible with PostgreSQL, and any system based on PostgreSQL can be seamlessly migrated to Halo.
