Zhen You Zhang, Bo Chen Sun, Zhi Wei Cao · Advanced materials research · 2013
Data island exists in most of the information system. And the system platform integration could eliminate the existence of the information island. This paper visited database information system through the EJB component technology, and using the metadata way to extracted data information from the heterogeneous database system, and it realized sharing information between the heterogeneous database system. In this system the B/S mode structure and EJB component technology, improve the system usability and expansibility.
