只要是數(shù)據(jù)庫那么就絕對(duì)離不開最為核心的功能：CRUD，所以在MongoDB里面對(duì)于數(shù)據(jù)的操作也是支持的，但是需要提醒的是，除了增加之外，其它的都很麻煩。

1、數(shù)據(jù)增加
使用“db.集合.insert()”可以實(shí)現(xiàn)數(shù)據(jù)的增加操作。
范例：增加一個(gè)簡單數(shù)據(jù)
> use hr
switched to db hr
> db.info.insert({"url":"www.stone.com"});
WriteResult({ "nInserted" : 1 })
> db.info.find();
{ "_id" : ObjectId("5990f8ea3268c8e84253ba3b"), "url" : "www.stone.com" }

范例：保存數(shù)組
> db.info.insert([{"url":"www.stone.com"},{"url":"www.stonedb.com"}])
BulkWriteResult({
        "writeErrors" : [ ],
        "writeConcernErrors" : [ ],
        "nInserted" : 2,
        "nUpserted" : 0,
        "nMatched" : 0,
        "nModified" : 0,
        "nRemoved" : 0,
        "upserted" : [ ]
> db.info.find();
{ "_id" : ObjectId("5990f8ea3268c8e84253ba3b"), "url" : "www.stone.com" }
{ "_id" : ObjectId("5990f97d3268c8e84253ba3c"), "url" : "www.stone.com" }
{ "_id" : ObjectId("5990f97d3268c8e84253ba3d"), "url" : "www.stonedb.com" }
如果想要保存多個(gè)數(shù)據(jù)，那么就使用數(shù)組。

范例：保存1000個(gè)數(shù)據(jù)
> for(var x=0;x<1000;x++){db.info.insert({"url":"stone_"+x});}
WriteResult({ "nInserted" : 1 })
> db.info.find();
{ "_id" : ObjectId("5990f8ea3268c8e84253ba3b"), "url" : "www.stone.com" }
{ "_id" : ObjectId("5990f97d3268c8e84253ba3c"), "url" : "www.stone.com" }
{ "_id" : ObjectId("5990f97d3268c8e84253ba3d"), "url" : "www.stonedb.com" }
{ "_id" : ObjectId("5990faea3268c8e84253ba3e"), "url" : "stone_0" }
{ "_id" : ObjectId("5990faea3268c8e84253ba3f"), "url" : "stone_1" }
{ "_id" : ObjectId("5990faea3268c8e84253ba40"), "url" : "stone_2" }
{ "_id" : ObjectId("5990faea3268c8e84253ba41"), "url" : "stone_3" }
{ "_id" : ObjectId("5990faea3268c8e84253ba42"), "url" : "stone_4" }
{ "_id" : ObjectId("5990faea3268c8e84253ba43"), "url" : "stone_5" }
{ "_id" : ObjectId("5990faea3268c8e84253ba44"), "url" : "stone_6" }
{ "_id" : ObjectId("5990faea3268c8e84253ba45"), "url" : "stone_7" }
{ "_id" : ObjectId("5990faea3268c8e84253ba46"), "url" : "stone_8" }
{ "_id" : ObjectId("5990faea3268c8e84253ba47"), "url" : "stone_9" }
{ "_id" : ObjectId("5990faea3268c8e84253ba48"), "url" : "stone_10" }
{ "_id" : ObjectId("5990faea3268c8e84253ba49"), "url" : "stone_11" }
{ "_id" : ObjectId("5990faea3268c8e84253ba4a"), "url" : "stone_12" }
{ "_id" : ObjectId("5990faea3268c8e84253ba4b"), "url" : "stone_13" }
{ "_id" : ObjectId("5990faea3268c8e84253ba4c"), "url" : "stone_14" }
{ "_id" : ObjectId("5990faea3268c8e84253ba4d"), "url" : "stone_15" }
{ "_id" : ObjectId("5990faea3268c8e84253ba4e"), "url" : "stone_16" }
Type "it" for more
> it
{ "_id" : ObjectId("5990faea3268c8e84253ba4f"), "url" : "stone_17" }
{ "_id" : ObjectId("5990faea3268c8e84253ba50"), "url" : "stone_18" }
