 ## 模块定位
 
-`dbms` 是 `system-ops` 下的数据库监控模块，当前先提供数据库监控菜单对应的后端基础入口。
+`dbms` 是 `system-ops` 下的数据库运维模块，当前支持 Oracle、MySQL 两类数据库运维能力，其中 Oracle 支持 `DATA_PUMP`、`JDBC_EXPORT`，MySQL 当前支持 `JDBC_EXPORT`。
 
 ## 当前接口
 
 - `GET /database/overview`
-  - 查询数据库监控基础信息。
+  - 查询数据库运维概览信息。
+- `POST /database/connections/list`
+  - 查询数据库连接配置。
+- `POST /database/connections/add`
+  - 新增 Oracle 数据库连接配置。
+- `POST /database/connections/update`
+  - 修改 Oracle 数据库连接配置。
+- `POST /database/connections/delete`
+  - 删除数据库连接配置。
+- `POST /database/connections/test`
+  - 测试 Oracle 数据库连接。
+- `POST /database/connections/tables`
+  - 查询 Oracle 表列表。
+- `POST /database/backups/create`
+  - 创建备份任务，默认使用 `DATA_PUMP`，可选 `JDBC_EXPORT`。
+- `POST /database/backups/tasks/list`
+  - 查询备份任务列表。
+- `GET /database/backups/tasks/status`
+  - 查询任务状态。
+- `POST /database/backups/files/list`
+  - 查询备份文件记录。
+- `POST /database/restores/create`
+  - 创建恢复任务。
+- `GET /database/restores/tasks/status`
+  - 查询恢复任务状态。
+- `POST /database/delete/backup-file`
+  - 删除备份文件，要求 `confirmText=确认删除`。
+- `POST /database/delete/task`
+  - 删除任务记录，要求 `confirmText=确认删除`。
+
+## 数据脚本
+
+- `src/main/resources/sql/system-ops/system-ops-init.sql`
+  - 系统运维菜单初始化脚本。
+- `src/main/resources/sql/system-ops/dbms-database-ops-init.sql`
+  - 数据库运维连接、任务、备份文件和恢复记录表结构。
+
+## 配置项
+
+建议通过环境配置覆盖：
+
+```yaml
+dbms:
+  backup:
+    storage-path: D:/dbms-backup
+    default-max-file-size-mb: 512
+    mysql-fetch-size: 1000
+  tools:
+    expdp-path:
+    impdp-path:
+```
+
+说明：
+
+- `backup.storage-path`
+  - `JDBC_EXPORT` 生成的 CSV 和元数据 JSON 的受管根目录。
+- `backup.default-max-file-size-mb`
+  - MySQL `JDBC_EXPORT` 默认分片大小，前端可通过 `maxFileSizeMb` 覆盖，默认 512MB。
+- `backup.mysql-fetch-size`
+  - MySQL `JDBC_EXPORT` 流式读取批量大小，默认 1000。
+- `tools.expdp-path`、`tools.impdp-path`
+  - Oracle Data Pump 工具路径；为空时尝试走系统 `PATH`。
+
+## 当前行为
+
+- 当前能力矩阵如下：
+
+| 数据库类型 | 连接测试 | 表列表 | JDBC_EXPORT | DATA_PUMP |
+| --- | --- | --- | --- | --- |
+| ORACLE | 支持 | 支持 | 支持 | 支持 |
+| MYSQL | 支持 | 支持 | 支持 | 不支持 |
+- 备份和恢复只允许基于已保存且连接可用的连接配置发起。
+- 新增连接前的测试接口仍可传 `temporaryPassword` 做临时连通性测试。
+- 备份任务异步执行，只有实际文件生成成功后才会写入 `dbms_backup_file` 记录。
+- `JDBC_EXPORT` 当前会生成两类文件：
+- MySQL `JDBC_EXPORT` 会按任务号创建独立备份目录，每张表独立 CSV，默认按 512MB 分片：
+  - 数据分片文件：`<table>_part001_yyyyMMdd_<taskNo>.csv`
+  - 元数据文件：`mysql_jdbc_export_metadata_yyyyMMdd_<taskNo>.json`
+- 备份任务支持停止和重新开始：
+  - `POST /database/backups/tasks/stop`
+  - `POST /database/backups/tasks/restart`
+- `JDBC_EXPORT` 恢复依赖元数据文件，不再允许缺少元数据直接发起恢复。
+- 删除备份文件时，会校验目标路径必须位于受管备份目录下，避免误删非备份文件。
 
 ## 当前限制
 
-- 当前只完成后端基础入口，不包含真实数据库连接状态、容量或性能指标探测逻辑。
+- `DATA_PUMP` 仍依赖部署机器可执行 `expdp`、`impdp`，并且 Oracle 侧已准备好 `directory` 对象和权限。
+- 当前代码要求 `DATA_PUMP` 连接配置里补齐可管理的 `directoryPath`，否则虽然 Oracle 端可能已导出成功，后端无法安全管理文件记录与删除。
+- `JDBC_EXPORT` 恢复当前仅覆盖表数据，不承诺恢复索引、约束、触发器、序列、存储过程、权限等数据库对象。
+- `TIME_RANGE` 模式当前只在 `JDBC_EXPORT` 场景真正参与查询过滤；`DATA_PUMP` 尚未接入 Oracle `QUERY` 参数。
+- MySQL `JDBC_EXPORT` 已实现按大小分片；Oracle `JDBC_EXPORT` 仍沿用原单文件导出路径。
+- 本轮仅完成代码路径和文档收口，未执行 `mvn` 编译、测试或真实库联调。
