1、摘摘 要要 税务数据交换信息系统的设计与实现税务数据交换信息系统的设计与实现 随着税务信息化的发展，大理地税的应用系统数量众多，但都相对独立， 不仅操作繁琐、不方便，而且无法充分利用各个系统中的数据。而在实际应用 中，大理地税和其他的政府部门，如工商局、国税局、信用系统等都有大量的 数据交互，这些数据交互的顺利与否深刻的影响着大理地税以及其他部门的数 据应用和业务办理，如何实现对大理地税与各部门的数据交换统一管理成为了 最重要的问题。因此，用标准的数据格式和数据交换规范，以实现不同硬件平 台，不同操作系统，不同语言平台应用，不同数据库之间的数据交换成为大理 地税急需解决的问题。为加强信息化对税
2、务管理的支撑作用，贯彻国家税务总 局税收工作要点，强化税源监控，实行科学化、规范化、精细化管理，大理地 税局启动新一轮信息化建设，开发大理地税综合数据交换平台（以下简称数据 平台） 。 该数据平台需要解决的问题：(1) 大理地税内部应用系统，利用数据平台 整合资源、规范应用。从税收管理的本质出发，抽象出所需数据的集合。将大 理地税各个应用系统中的异构的信息资源整合在一起，统一数据口径，改进数 据质量，尽可能地满足数据共享的要求。(2) 利用数据平台与外部门进行数据 交换，解决部门之间的数据结构差异问题，实现大理地税与其他各部门之间的 各类数据集中交换；以及实现大理地税与各部门的数据交换统一管理
3、，对所有 数据交换的流程订制、监控管理、报表统计等。 论文以大理地税内部数据交换以及外部数据交换的实际需求为背景，采用 MVC 设计模式、Struts 框架、Java 软件开发语言以及数据库技术等进行研发。 论文的主要工作如下： 首先，对大理地税研发该系统的背景、意义以及国内外研究现状进行分析， 确定了论文的主要研究内容。 其次，采用面向对象的分析方法，对大理地税内部工作人员以及有业务往 摘 要 II 来的外部工作人员进行业务需求分析，分析现有业务流程存在的问题，并对其 进行优化处理，得到系统的功能需求分析，包括的功能主要有：数据库之间的 信息交换、外部门与地税部门信息传输、元数据管理以及系统
4、管理等，并对系 统数据流向进行了明确的分析。按照实际运行环境的需求，对系统在性能方面 的需求进行了说明。 然后，根据需求分析的结果，对系统的体系架构、功能架构以及数据库进 行了全面的设计。 最后，对系统的功能进行实现，并对实现后的系统进行全面的测试，通过 测试结果可知，该系统满足了用户的需求。 本设计的数据平台满足了大理地税数据交换的业务需要，实现了数据的整 合，同时在此基础上开发了新的应用，实现了信息资源的最大增值，为领导决 策提供准确的数据支持。该系统已经在大理地税全面启用，目前使用情况良好。 关键词：关键词：税务信息交换；地税外部信息交换系统；Java Abstract III Abst

In practice, there are a large number of data interaction Dali rent and other government departments, such as the Trade and Industry Bureau, the IRS, the credit system, the smooth interaction of these data or not a profound impact on data applications Dali tax and other departments and
7、 business process, how to achieve the data exchange Dali tax and various departments unified management has become the most important issue. Thus, using standard data formats and data exchange standards, in order to achieve different hardware platforms, data between different operating systems, diff

In order to strengthen the supporting role of information technology in tax administration, and implementing the main points of the State Administration of Taxation, and strengthen the monitoring of t
9、ax sources, implementation of scientific, standardized, meticulous management, Dali Inland Revenue Department to launch a new round of information technology, the development of integrated data exchange Dali rent platform (hereinafter referred to as data platform). The data platform issues to be add
10、ressed: (1) internal applications Dali tax system, using data integration platform resources, standardizing applications. Starting from the nature of tax administration, collection of abstract data required. Dali tax will integrate various application systems in heterogeneous information resources t
