摘要
在Shapefiles空间数据序列化的基础上,讨论了怎样在SQLServer上建立含有二进制大对象(BLOB)类型数据的数据表,介绍了利用ADO.NET技术在内存中建立对应数据表(DataTable)的方法;通过连接(SqlConnection)对象、命令(SqlCommand)对象和数据适配器(SqlDataAdapter)对象等实现了在两个数据表间存取空间数据和属性数据,进而可以高效地进行GIS应用开发。
On the basis of the serialization of spatial data in Shapefiles, the method for creating data table with BLOB data type in SQL Server was discussed. The scheme of creating corresponding DataTable in memory by ADO. NET technology was also introduced. By the utility of SqlConnection, SqlCommand, SqlDataAdapter and etc, the accessing of spatial data and attribute data between two data tables was realized, which could make the development of GIS application more efficient.
