ABSTRACT
The access of Web based titanium metallurgy database is achieved by web in the modified multylagers Web based titanium metallurgy database. Therefore, access-management mechanism has large effect on the whole system, even is the bottleneck of the system performance. The main compose of Web based titanium metallurgy database is the permanent data saved on the disc. The data must been connected with the backstage when the data are dealled with. Therefore, how to manage the access of those databases has been the main assignment in the Web based titanium metallurgy database system.
