The classification methods for structural data and non-structural data;

The concept of information dynamic route based on information organization model was put forward,and the structural or the semi-structural data query was completed using the information route from host.

Starting from the object\|oriented ideas, and interrelations of product drawings, the paper presents the united managment method of structural and non\|structural data related to product drawings.

It changed from structured data management to non-structured data management.

This information system solves the integrated application of structured data and unstructured data, and integrates some important enterprise applications.

With the ever-increasing development of Internet, today抯 data-centric applications require storage platforms not only to possess some properties including high capacity and high scalability, but also to support structured data directly, which is beyond the abilities of current file systems and DBMS.

BPL Pulse Positioning Modulation and Data Transmission;

The Design and Implementation of Data Transmission Module of Configuration Management in UEP;

Utilizing microcomputer parallel print port, data transmission that has quick transfer speed and simple system can be realized.

The application of universal interface USB OTG technology in data transfer;

This paper proposes Control-Splitted Data Transfer(CSDT),a novel method for processing data transfer requests between client devices of a transparent system.

Application results show that the device with a lower cost,higher anti-interference capacity is up to the requirements of almost all kinds of liquid level measurement in oil tank and data transfer.
