本节主要来说说如何将数据插入到mongodb集合中。所有存储在集合中的数据都是BSON各式的。BSON是一种以二进制存储的json格式。当数据插入时，使用的驱动程序会将数据转成BSON格式，然后插入集合中。数据库解析BSON，检查是否包含”_id”键，并且集合文档不得超过4MB，除此之外，不做任何其他的检查。如果要对插入的文档进行检查，可以在启动服务时候使用–objcheck参数，这样会在插入前先进行文档结构的有效性检测，当然啦，性能方面会有所降低的。定义一个文档：
> use ttlsa_comswitched to db ttlsa_com> document=({"user_id" : "ABCDBWN","password" :"ABCDBWN" ,"date_of_join" : "15/10/2010" ,... "education" :"B.C.A." , "profession" : "DEVELOPER","interest" : "MUSIC",... "community_name" :["MODERN MUSIC", "CLASSICAL MUSIC","WESTERN MUSIC"],... "community_moder_id" : ["MR. BBB","MR. JJJ","MR MMM"],... "community_members" : [500,200,1500],"friends_id" : ["MMM123","NNN123","OOO123"],... "ban_friends_id" :["BAN123","BAN456","BAN789"]});{ "user_id" : "ABCDBWN", "password" : "ABCDBWN", "date_of_join" : "15/10/2010", "education" : "B.C.A.", "profession" : "DEVELOPER", "interest" : "MUSIC", "community_name" : [ "MODERN MUSIC", "CLASSICAL MUSIC", "WESTERN MUSIC" ], "community_moder_id" : [ "MR. BBB", "MR. JJJ", "MR MMM" ], "community_members" : [ 500, 200, 1500 ], "friends_id" : [ "MMM123", "NNN123", "OOO123" ], "ban_friends_id" : [ "BAN123", "BAN456", "BAN789" ]}
输入集合中：
> db.test_ttlsa_com.insert(document)
该操作会给文档自动添加一个”_id”键，然后将其保存到mongodb中。也可以不预先定义文档直接插入：
> db.test_ttlsa_com.insert({"user_id" : "ABCDBWN","password" :"ABCDBWN" ,"date_of_join" : "15/10/2010" ,"education" :"B.C.A." , "profession" : "DEVELOPER","interest" : "MUSIC","community_name" :["MODERN MUSIC", "CLASSICAL MUSIC","WESTERN MUSIC"],"community_moder_id" : ["MR. BBB","MR. JJJ","MR MMM"],"community_members" : [500,200,1500],"friends_id" : ["MMM123","NNN123","OOO123"],"ban_friends_id" : ["BAN121113","BAN456aaa"]})
查看数据：
