微对象的初入（2）
（一）存储选择：微型对象数据库
这里是随笔，不会详述内容，下面都是用实验样例来解释说明。
1。微型对象数据库
例：
{ "食指"：{ "对象名":"食指" "左右手":"左手" "属性":[ {"重量":"0.1公斤"}, {"肤色":"黄"}, {"皮肤面积":"0.05平米"}, {"血":"0.001公斤"}, {"骨":"0.002公斤"}, {"皮":"0.001公斤"}, {"肉":"0.005公斤"}, {"指甲":{...}}, 。。。 ] "行为":[ {"掌":""}, {"拳":""}, {"1":"手势"}, {"指示方向":"手势"}, {"勾勾手":"手势，来我这儿"}, 。。。 ] } }
1.1 NOSQL库实现
1.1.1 对象类型
