| Abstract: | Data access of Large Object(LOB)is a key technique of data permanence in Object Oriented software develop- ment.Firstly,the basic kind and access mode of LOB are introduced,and common algorithm of data access of LOB based on JD- BC is probed into.Then,it is presented that application instance of data access of BLOB in network electron document manage system based on Oracle,DB2 and MySQL etc.Lastly,the new characteristic of LOB in JDBC 4.0 is pointed out. |
