-- 1. 存储模块定义（例如：AI 决定创建一个“线索管理”模块，它的字段定义存这里） |
|
CREATE TABLE sys_entities ( |
|
id UUID PRIMARY KEY DEFAULT gen_random_uuid(), |
|
entity_code VARCHAR(50) UNIQUE NOT NULL, -- 模块标识，如 'crm_lead' |
|
entity_name VARCHAR(100) NOT NULL, -- 模块名称，如 '销售线索' |
|
schema_definition JSONB NOT NULL, -- 核心：存储字段定义的 JSON (类型、标签、校验) |
|
created_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP, |
|
updated_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP |
|
); |
|

|
-- 2. 存储动态业务数据（所有的业务数据都进这一张表，靠 entity_id 区分） |
|
CREATE TABLE sys_dynamic_data ( |
|
id UUID PRIMARY KEY DEFAULT gen_random_uuid(), |
|
entity_id UUID REFERENCES sys_entities(id), |
|
data JSONB NOT NULL, -- 核心：存储具体的业务字段数据 |
|
created_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP, |
|
creator_id VARCHAR(50) -- 预留租户或用户 ID |
|
); |

|
-- 3. 存储 AI 会话记忆（LangChain4j 自动持久化对话用） |
|
CREATE TABLE chat_memory ( |
|
id SERIAL PRIMARY KEY, |
|
chat_session_id VARCHAR(255) NOT NULL, |
|
content TEXT NOT NULL, -- 存储对话内容 |
|
created_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP |
|
); |
|
|
|
-- 为 JSONB 字段创建 GIN 索引，保证以后千万级数据的查询速度 |
|
CREATE INDEX idx_entity_data ON sys_dynamic_data USING GIN (data);
