ArcGIS10的GDB文件解析（初步）

早就應該寫一寫關於esri的一些改變

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

版本10.0以上，測試環境10.2

新建一空mdb格式的GDB文件，access打開，會發現跟9.x徹底不同，參考esri提供的幫助，能夠大概知道，主要是爲了順應xml格式的趨勢而作出了改動，

可在我看來，這些改動，把原來簡單的事情變複雜了~^_^

新建dataset-新建featureClass，發現本來關於字段別名的定義不見了~

查看GDB_Items表的字段Definition能夠發現，原來把table格式的定義換成了xml定義，複製出來，看一究竟
