ArcGIS10的GDB文件解析（初步）

早就应该写一写关于esri的一些改变

参考http://resources.arcgis.com/zh-cn/help/main/10.1/index.html#//006z000000tr000000

版本10.0以上，测试环境10.2

新建一空mdb格式的GDB文件，access打开，会发现跟9.x完全不一样，参考esri提供的帮助，可以大概知道，主要是为了顺应xml格式的趋势而做出了改动，

可在我看来，这些改动，把原来简单的事情变复杂了~^_^

新建dataset-新建featureClass，发现原本关于字段别名的定义不见了~

查看GDB_Items表的字段Definition可以发现，原来把table格式的定义换成了xml定义，复制出来，看一究竟
