-- ============================================
|

-- 数据分析实时大屏 - 基础业务表结构（创建版 / Create-only）
|
||
-- ============================================
|
||
-- 用途：创建业务核心表（orders, users, user_sessions, products, merchants 等）
|
||
-- 特点：
|
||
-- 1. 不做 DROP/DELETE/TRUNCATE（不清空数据）
|
||
-- 2. 通过 IF NOT EXISTS + 系统表判断，实现可重复执行
|
||
-- 3. 与 analytics_* 表（ANALYTICS_DB_SCHEMA.sql）配套使用
