Syncml defines a synchronization protocol that uses xml messages for add , remove , and modification of the data units Syncml定义了一个同步协议,使用xml消息来添加、删除和修改数据单元。
On these basis , we analyse its protocol data unit and how to create a ldap database , operate this database 在此基础上详细分析它的协议数据单元,以及如何建立ldap数据库、操作ldap数据库。
For two - way replication , we also need a mapping scheme to identify corresponding units of data between the databases 对于双向复制,还需要一个能够标识数据库之间对应数据单元的映射方案。
A delimiter , a character that separates units of data in storage or transmission , ( “ a file separator ” , “ a field separator ” ) 一种定界符,即在存储和传输中分隔数据单元的一种字符(文件分隔符、字段分隔符) 。
The exception that is thrown when a unit of data is read from or written to an address that is not a multiple of the data size 在从不是数据大小倍数的地址读取数据单元或将数据单元写入此类地址时引发的异常。
In the case of relational databases , you can use additional fields to record the data unit s state and a timestamp of the state change 在关系数据库中,可以用附加字段来记录数据单元的状态和状态变化的时间戳。
For example , a routine in your application attempts to copy a sequence of bytes from one location to another in 64 - bit units 例如,应用程序的某一例程尝试以64位数据单元的形式将字节序列从一个位置复制到另一个位置。
1 . the transact - sql statement used to return data to an application or another transact - sql statement , or to populate a cursor 1 .在text 、 ntext和image数据中,数据块指在应用程序与sql server实例之间一次传输的数据单元。
The result of simulation approve that our approaches can reduce the delay of the transmission of msdu , improve the performance of the network 通过仿真分析,证实了此方法的可行性,并且能够有效减小数据单元的发送时间。
