Question: The following sql statement is used for dedecms system upgrade, and I often encounter dede_.
Excuse me, what does dede_ mean? Like a mess.

以下为引用的内容：
REPLACE INTO `dede_sysconfig` VALUES(744, 'cfg_replace_num', '文档内容同一关键词替换次数(0为全部替换)',  7, 'number', '2');
REPLACE INTO `dede_sysconfig` VALUES(745, 'cfg_uplitpic_cut', '上传缩略图后是否马上弹出裁剪框', 3, 'bool', 'N');

The following is the quoted content:

REPLACE INTO `dede_

sysconfig` VALUES(744 , 'cfg_replace_num', 'Number of times to replace the same keyword in the document content (0 means all replacements)', 7, 'number', '2');

REPLACE INTO `dede_sysconfig` VALUES(745 , 'cfg_uplitpic_cut', 'Whether the cropping box pops up immediately after uploading the thumbnail', 3, 'bool', 'N');
