Data management apparatus that controls a data storage apparatus by transmitting command of structured document format

摘要

A data management apparatus connected to a data storage apparatus via a network manages the data storage apparatus by transmitting a command of structured document format such as the extensible markup language format and receiving the information related to the executed command as response data of the structured document format. Since the information included in the command is expressed using the structured document format, the data storage apparatus can flexibly interpret the command by ignoring missing and excess information included in the command, and vice versa.
