想请问mimic数据库这个chartevents是怎么做到又分成了chartevents1/2/3...这些亚组的
我从官网下载的就只有整个的chartevents,这样的话我每次搜索都在整个组里搜索,每次都花好几分钟,特别慢
还有有没有mimic交流群呀,想一起交流🎤
提供参考实例:mimic数据库查询加速教程,链接:https://cdn.modb.pro/db/480922
MIMIC 数据库将 chartevents 划分为多个亚组是为了提高搜索的效率。这样可以在单独的亚组内进行搜索,而不是在整个 chartevents 表中搜索。这样可以大大减少搜索所花费的时间。
可以使用 SQL 语句来查询每个亚组中的数据:
SELECT * FROM chartevents1 WHERE itemid = 50850;
这样就可以在 chartevents1 表中快速搜索 itemid 为 50850 的数据了。
仅供参考,望采纳,谢谢。
One way to group the data in the MIMIC database chartevents table is to use the "itemid" column, which specifies the type of data being recorded. For example, you could group all vital sign data together, all medication data together, and all lab test data together. Another way to group the data is to use the "subject_id" column, which identifies the patient the data belongs to. This would allow you to group the data by individual patient. Alternatively, you could use the "charttime" column to group the data by time periods, such as by day or by hour.
