Research And Application Of Multi-tier Distributed System Based On EAS/JAGUAR

The basic realization methods of multi-tier distributed system based on the technology of EAS/Jaguar are the main topic, the problems such as connecting buffer, data update, lifecyle and transaction management which are related to the whole performance of the application system are also Analysisd,the technology of PowerDynamo/CTS WEB and DDE are also discussed. By introducing object-oriented technology and UML, the methods and guidelines of the analysis and design of applying UML in multi-tier distributed system are basicly discussed.Based on above technology, and combined the Characteristic of label Realm , The author designed the Label Management Information System of FangZhou And surround problem that related core technique and relevant proceeds research and application: Realized the backstaged of printing base on jaguar technique, Realized the automatic renewal of the customer interface procedure, Made use of the DDE technique to realizes the data importing of Excel backup base on Jaguar CTS, Made use of Jaguar and database technology to realizes the quick data searching,The system use PowerBuilder9.0 as programming platform and Oracle8.0 as database.
