The system uses Microsoft ASP. NEF as development platform, C as the server language, and Microsoft Visual Studio 2008 as the development tool. ADO. NET is used to connect with SQL SERVER 2000 database through the data- base controls. A variety of server controls are used to create the ASP. NET page to implonent the syste^n functions. The syston is designed in 3-Layer application which includes Presentation Layer （PL）, Busi- ness Logic Layer （BLL） and Data Access Layer （DAL）. The operation of the database is in DAL, the logic fimction is in BLL. So the amotunt of work in the development, the difficulty of system maintenance and the upgrading can be reduced. After being tested, the system meets the requirement of the users.展开更多

EOS is responsible for the entire software and hardware resource allocation, scheduling work and coordinating concurrent control activities; some more successful applied EOS products have been presently launched. With the development of lnternet technology, information appliances and the universal application of miniaturization and specialization of EOS, EOS started from a single weak situation to a higher professional direction with strong functions.展开更多
