Equipment Management Information System Integration Based on Standard Data Element
JI Ya-lin · Ordnance Industry Automation · 2007
Through standardizing system integration method of equipment management data element, the whole system is divided into 3 layers. They are data element layer, data storage layer and user end. User end and data storage layer are connected by data access interface. Data access interface defines the mapping relation and access mechanism between user and data storage layer, which sets user’s right as RWAD (Read, Write, Amend, Delete). The system user and the advanced user have all rights of RWAD. But the un-system user can only access other system according with its right. This paper settles the problem of information islands by standardizing data’s format and expression mode of every branch system.
