1 概述
燃气服务评价综合管理系统,其开发主要包括后台数据库的建立和维护以及应用程序的开发两个方面。对于数据库要求建立起数据一致性和完整性强、数据安全性好的数据库，而对于后者则要求应用程序功能完备,易使用等特点。该燃气服务评价综合系统实现的功能有:系统管理、燃气产品管理、客户管理、服务信息管理、电话咨询管理。
本系统采用B/S模式，主要实现的功能如下：
系统管理：该模块实现的功能有系统属性、管理员维护、修改密码。主要是对系统的维护信息的分析；
燃气产品管理：该模块实现的功能有产品分类、添加分类、燃气产品管理、添加产品。产品分类主要是对分类管理的添加、删除修改；燃气产品管理主要是对产品信息进行添加、删除、修改等，如类别、名称、产地、单位 、规格等；
客户管理：该模块实现的功能有客户管理、添加客户。主要是对客户信息的添加、删除、修改，如姓名、性别、年龄、联系电话、住址；
服务管理：该模块实现的功能有故障维修登记、服务登记、故障量统计。故障维修管理主要是对服务信息的添加、删除、修改。如单据号、故障维修时间、总金额、经手人、明细等；服务登记主要是对服务登记信息的添加、删除、修改，如单据号、登记者时间、总金额等；故障量统计主要是对故障信息的统计，如产品名称、统计数量；
电话咨询管理：该模块实现的功能有电话咨询管理、添加电话咨询。电话咨询管理主要是对电话咨询信息进行添加、删除、修改，如电话咨询产品、到期时间、电话咨询费用、支付方式、顾客姓名等；
