MongoDB uses Flexgrid's simple data to present this example. This example uses the commonly used: User, post, comment as the basic model to implement a simple Demo of MongoDB's combination of Flexgrid data presentation. Due to time limitations, the function only provides common query operations (paging, sorting, and query) for

MongoDB is a popular nosql software. It has released versions on Windows Linux Mac platform. After testing, the efficiency is still very good, but the memory consumption is very high because mapviewoffile is used, that is, the hard disk data is mapped directly to the memory, so the entire memory needs to be loaded (http://www.cnblogs.com/daizhj/archive/2011/04/25/mongos_mmap_source_code.html ).
