The paper introduced the binary large objects technology in database,and studied the Read-Write method based on the SDE for the spatial data.Then it advanced a kind of project based on the binary large objects for managing the spatial data,and implemented it by a demo data.It was proved that the project resolved a problem at a certain extent,that it is troublesome to make use of ArcEngine reading and writing the notes,and improved the efficiency of searching the spatial data.
