-Database 节点名只支持中英文字符、数字、下划线、英文句号和反引号的组合，如果想设置为纯数字或者包含下划线和英文句号，需要用反引号(` `` `)把
database 名称引起来。其中` `` `内，两个反引号表示一个反引号，例如 ` ```` ` 表示`` ` ``。
+Database 节点名命名规则:
+1. 节点名可由**中英文字符、数字、下划线（\_）、英文句号（.）、反引号（\`）** 组成
+2. 若节点名为以下情况，则必须用**反引号（\`）** 将整个名称包裹。
+ - 纯数字（如 12345）
+ - 含有特殊字符（如 . 或 \_）并可能引发歧义的名称（如 db.01、\_temp）
+3. 反引号的特殊处理：
+若节点名本身需要包含反引号（\`），则需用**两个反引号（\`\`）** 表示一个反引号。例如：命名为\`db123\`\`（本身包含一个反引号），需写为
\`db123\`\`\`。
+
还需注意，如果在 Windows 系统上部署，database 名是大小写不敏感的。例如同时创建`root.ln` 和 `root.LN` 是不被允许的。
