# FMS 新系统核心表结构设计

## 1. 说明

本文档给出 FMS 新系统核心平台表的 SQL Server 建表语句，范围包括元数据、动态表单、配置版本、Schema 迁移、权限、技术日志、登录日志与业务审计。

约定如下：

- 所有表名以 `s_` 开头，字段名以 `b_` 开头。
- 表名、字段名、索引名和约束名统一使用 `snake_case`。
- 不创建物理外键，关联字段只作为逻辑外键使用。
- 逻辑外键必须创建必要的普通索引或唯一索引。
- 一个租户使用一个独立业务数据库，普通业务表不重复保存 `b_tenant_id` 或 `b_org_id`；集中技术日志和登录日志允许使用 `b_org_id` 标识日志来源。
- 内部主键统一使用 `bigint identity(1, 1)`，跨环境标识使用稳定的 `b_*_key`。
- 同库内的逻辑关联 ID（例如 `b_form_id`、`b_release_id`）统一使用 `bigint`，不使用 `uniqueidentifier`。
- 业务编号（例如 `b_change_set_no`、`b_release_no`）使用 `bigint`，由应用或数据库序列生成，不声明为 `identity`。
- 时间点统一使用 `datetime2(3)`，应用层按 UTC 写入。
- 稳定业务标识统一使用 `b_*_key`，跨环境导入导出不得依赖内部 `b_id`。
- 扩展内容统一使用 `nvarchar(max)` 普通文本保存，由应用层按业务约定解析和校验，不使用 JSON 字段类型。
- 原布尔语义字段统一使用 `tinyint`，取值约定为 `0`（否）或 `1`（是）。
- 下面的 `b_*_id`、`b_*_key` 关联均为逻辑外键，由应用服务负责校验一致性。

本文档只定义平台核心表。海运订舱、集装箱、发票等业务实体表由 Schema Compiler 根据 `s_meta_entity`、`s_meta_field` 和 `s_meta_relation` 生成。

## 2. 元数据中心

    on dbo.s_meta_dictionary_item (b_dictionary_id, b_enabled, b_sort_no);
```

### 2.6 注册查询资源

```sql

    on dbo.s_meta_query_source (b_module_key, b_enabled);
```

### 2.7 页面与菜单

页面是可访问的业务入口，负责把运行时视图、表单或特殊 Vue 组件绑定到稳定路由和页面权限。菜单是页面和模块的导航表现，可以配置目录、页面和外链，但不能替代页面访问权限判断。

```sql
create table dbo.s_meta_page (
    b_id bigint identity(1, 1) not null,
    b_page_key nvarchar(192) not null,
    b_revision_no int not null,
    b_module_key nvarchar(128) not null,
    b_name_key nvarchar(256) not null,
    b_page_type nvarchar(32) not null,
    b_route nvarchar(256) not null,
    b_component_key nvarchar(192) null,
    b_view_key nvarchar(192) null,
    b_form_key nvarchar(192) null,
    b_permission_key nvarchar(192) not null,
    b_visible tinyint not null
        constraint df_s_meta_page_visible default 1,
    b_enabled tinyint not null
        constraint df_s_meta_page_enabled default 1,
    b_protected tinyint not null
        constraint df_s_meta_page_protected default 0,
    b_config_text nvarchar(max) null,
    b_created_at datetime2(3) not null
        constraint df_s_meta_page_created_at default sysutcdatetime(),
    b_created_by nvarchar(128) not null,
    constraint pk_s_meta_page primary key (b_id),
    constraint ux_s_meta_page_key_revision unique (b_page_key, b_revision_no)
);

create index ix_s_meta_page_module_key
    on dbo.s_meta_page (b_module_key, b_enabled);

create index ix_s_meta_page_route
    on dbo.s_meta_page (b_route, b_enabled);

create table dbo.s_meta_menu (
    b_id bigint identity(1, 1) not null,
    b_menu_key nvarchar(192) not null,
    b_revision_no int not null,
    b_module_key nvarchar(128) not null,
    b_parent_menu_key nvarchar(192) null,
    b_name_key nvarchar(256) not null,
    b_menu_type nvarchar(32) not null,
    b_page_key nvarchar(192) null,
    b_route nvarchar(256) null,
    b_permission_key nvarchar(192) null,
    b_icon_key nvarchar(128) null,
    b_sort_no int not null
        constraint df_s_meta_menu_sort_no default 0,
    b_visible tinyint not null
        constraint df_s_meta_menu_visible default 1,
    b_enabled tinyint not null
        constraint df_s_meta_menu_enabled default 1,
    b_config_text nvarchar(max) null,
    b_created_at datetime2(3) not null
        constraint df_s_meta_menu_created_at default sysutcdatetime(),
    b_created_by nvarchar(128) not null,
    constraint pk_s_meta_menu primary key (b_id),
    constraint ux_s_meta_menu_key_revision unique (b_menu_key, b_revision_no)
);

create index ix_s_meta_menu_parent_key
    on dbo.s_meta_menu (b_parent_menu_key, b_sort_no, b_enabled);

create index ix_s_meta_menu_page_key
    on dbo.s_meta_menu (b_page_key, b_enabled);
```

约束由元数据校验器执行：`directory` 菜单不能绑定页面或路由，`page` 菜单必须绑定 `b_page_key`，`external` 菜单必须填写 `b_route` 和 `b_permission_key`；内部页面菜单的路由必须从页面资源解析，不能单独维护第二份内部路由，权限默认继承所绑定页面的 `b_permission_key`。目录仅在至少存在一个可访问子页面时显示。

### 2.8 列表与详情视图

```sql
create table dbo.s_meta_view (
    b_id bigint identity(1, 1) not null,
    b_view_key nvarchar(192) not null,

## 6. 逻辑外键清单

以下关联不创建物理外键，由服务层、发布校验器和 Schema Compiler 负责检查：

| 表 | 字段 | 逻辑目标 |
| --- | --- | --- |
| `s_meta_entity` | `b_module_key` | `s_meta_module.b_module_key` |

逻辑外键写入时应执行以下校验：

```text
稳定 key 是否存在
-> 目标资源是否属于当前 release
-> 目标资源是否启用
-> 模块依赖是否合法
-> 字段、关系和页面类型是否匹配
-> 删除或停用前是否仍被其他资源引用
```

## 7. 实施建议

建议按以下顺序创建和启用这些表：

```text
元数据基础表
-> 页面和菜单表
-> 视图和动态表单表
-> 配置 release 表
-> Schema 迁移表
-> 权限表
-> 日志与审计表
```

正式执行前还应补充：

- 根据实际 SQL Server 2022 环境确认过滤索引和 `datetime2` 支持情况。
- 根据现有用户表确定 `b_user_key`、`b_created_by` 和 `b_updated_by` 的实际数据类型。
- 根据最终稳定 key 长度评估唯一索引的键长度。
- 为高数据量审计表制定归档及清理策略。
- 用独立测试数据库执行完整建表脚本，并验证重复安装、初始化 release 和回滚流程。
