de是Spatial Database Engine简写，中文全称：空间数据库引擎。
SDE是一种客户/服务器软件，可使空间数据在工业标准的数据库管理系统中存储、管理和快速查询检索。把GIS数据放在RDBMS中，但是一般的RDBMS都没有提供GIS的数据类型（如点、线、多边形、以及这些feature之间的拓扑关系和投影坐标等相关信息），RDBMS只提供了少量的数据类型支持：int，float，double，Blob，Long ，char等，一般都是数字，字符串和二进制数据几种。并且RDBMS不仅没有提取对GIS数据类型的存储，也没有提供对这些基础类型的操作（如：判断包含关系，相邻、相交、求差、距离、最短路径等）
JAVA对sde操作，首先需要下载sde支持的jar包。jpe92_sdk.jar和jsde92_sdk.jar两个包，这两个包可以从安装的目录下找到。
下面是java获的sde的链接代码：
[java]
/**
* 连接sde服务
* @return
*/
public SeConnection getConnection () {
SeConnection conn = null ;
try {
conn = new SeConnection(SDE_SERVER_IP, SDE_PROT, SDE_DATEBASE_SID, SDE_USERNAME, SDE_PASSWORD);
} catch (SeException e) {
return null;
}
return conn;
}
/**

*/
public SeConnection getConnection () {
SeConnection conn = null ;
try {
conn = new SeConnection(SDE_SERVER_IP, SDE_PROT, SDE_DATEBASE_SID, SDE_USERNAME, SDE_PASSWORD);
} catch (SeException e) {
return null;
}
return conn;
}
