Park so long time, also should write something, recently in using node to write things, oneself is not very familiar with, how to set up the environment simply say, for reference only.I was developed under the Win7 environment.1.

Install the mongo,http://www.mongodb.org/downloads and configure it to boot from the service, see other blog posts.3. Install git, http:
The previous five comparisons have received positive feedback from everyone, as well as individual experts who have written me the code I write.I wrote the query method of the performance problems, I think, if MONGO is not delayed loading, then my query is really a problem, it became a query out all the data and then two times to filter.Maybe this is also the habitual use of the Entity Framework framework. Today hurriedly carried out a bit of code, no
Write to the second one has to say that I made a small mistake before, in fact, the implementation of the sub-table storage is very simple, first of all I want to achieve what kind of effect itIs that the user table has a score field, the score field is a child tableActually realizes this function is also very simple, uses the object-oriented thought to understand very well, the child table is an object field or the collection field of the user table, so I think the development of C #
Today, the main test of the query function, of course, is mainly to let the query and we usually use the entity object associated with, and those bsondocument and collection we operate is not too convenientOr first define a user class, notice that this class needs to match the field of the object in the MONGO exactly, including the case, otherwise the field cannot match the error when the query occurs Public class User { publicgetset;}

Some conceptsFor MONGO in data disaster recovery, the recommended pattern is to use replica set mode, which has an external primary server primary, and N replica server secondary (n>=1, when n=1, need to have an arbiter server arbiter when n> 1 o'clock does not require arbiter), they were previously synchronized through the internal mechanism, and when primary hung, it will be through the internal heartbeat mechanism, the election of a secondary to be
