**1．****什么是报表开发？**

**报表开发就是根据指定的规则,把业务数据按照一定的形式展现给用户的技术。**

**2．****报表开发发展历史**

**【手工绘制(效率低、容易出错)】 \---->【Excle工具软件(降低了报表开发效率、准确性提高)】\---->【定制报表系统(根据业务数据自动生成)】**

**3．****报表****开发分类(一般按照业务系统的架构进行分类)****:**

**C/S架构：**

**①　****客户端/服务器端(C/S)：可以借助平台自带API(如java的Swing组件),实现丰富的用户交互功能,增强用户体验。**

**②　****第三方报表控件:例如在java中选择****JFreechart、JasperReports****来实现各种复杂的报表。**

**B/S架构：**

**③　****浏览器/服务器(B/S):采取了基于浏览器的策略,简化客户端的开发工作。在B/C结构的服务器端,不用处理通信相关的问题,Web服务器会吃力用户HTTP请求等通信问题,开发人员只需要专注于业务逻辑功能的实现。**

**④　****B/S没有C/S那么丰富的界面元素可以调用、也没有C/S中那么灵活的事件调用机制。**

**⑤　****第三方报表控件：如java的J****Freechart、JasperReports****，或其它报表控件(Highcharts)。**

**4．****报表的****表现形式:**
