With the rapid development of computer application and network technology, information is becoming more and more important, and it affects the whole society with a fleet speed. So, more and more business of taxation and management of Hu Nan National Revenue are done by modem information technology. Considering individual business of taxation and management, in order to encourage consumers to ask for invoices and strengthen the management of invoices, Invoice Management System Based on Telephone Voice is demanded to develop by Hu Nan Tax Bureau, via making full use of computers and network resources.According to the sufficient analysis of business requirement, function modules, topology, database system and data exchange of the system are detailedly expounded in this paper. In particular, the development model and the scheme of data exchange of this system are discussed.The latest research products of Modem Computer Telephone Integration are applied in Telephone Voice Subsystem. Analogue relay voice card and system software of Chinese TTS are used to support multipile telephone chunnels to play TTS voice, in order to switch and play in real time. The development tool of Powerbuilder9.0 is utilized to develop client application programs in invoice draw subsystem. Three-tier architecture based on B/S is adopted in network querying invoices subsystem, monitoring and analysizing invoices subsystem. The interface tier adopts JSP to visit the Web server. The middle tier stores business logic described by JavaBean technique. And development tool of InforReport is used to make reports in Java. The bottom tier is to exchange data in the form of XML in heterogeneous databases by Oracle9i.The whole system realizes such functions as collecting and inputing invoice information, drawing invoice, analysizing invoice data, quering invoice prize information, maintaining system, prosecuting on the internet, importing invoice imformation and exporting draw data. So this is an integrated information management system in Hu Nan National Revenue.This applicaton system has come into use now.
