It’s not very sophisticated. 4D pushes data to PostgreSQL, or retrieves data from PostgreSQL, based on either user-triggered actions or periodic task execution. At no point does the Rails/PostgreSQL system access 4D. The fact that 4D uses SQL to access the PostgreSQL database has specific disadvantages, such as updates involving schema changes needing to have coordinated release.
