Gambas 语言实战开发智能物流供应链金融系统
随着互联网技术的飞速发展，物流行业和金融行业逐渐融合，形成了智能物流供应链金融系统。这种系统通过信息技术手段，实现了物流、信息流和资金流的有机整合，为供应链上下游企业提供了一种新型的金融服务。本文将围绕Gambas语言，探讨如何实战开发智能物流供应链金融系统。
Gambas语言简介
Gambas是一种开源的、基于BASIC语言的编程语言，它具有易学易用、跨平台等特点。Gambas语言提供了丰富的库和组件，可以方便地开发桌面应用程序、网络应用程序和嵌入式应用程序。在智能物流供应链金融系统的开发中，Gambas语言可以作为一种有效的工具。
系统需求分析
在开发智能物流供应链金融系统之前，我们需要对系统进行需求分析。以下是一些基本的需求：
1. 用户管理：系统应具备用户注册、登录、权限管理等功能。
2. 物流信息管理：包括物流订单管理、运输管理、仓储管理等。
3. 金融信息管理：包括贷款申请、审批、还款等功能。
4. 数据统计分析：对物流和金融数据进行统计分析，为决策提供支持。
5. 系统安全：确保系统数据的安全性和可靠性。
系统设计
技术选型
- 前端：Gambas GUI库
- 后端：Gambas SQL库
- 数据库：MySQL或SQLite
系统架构
系统采用B/S架构，分为前端和后端两部分。
- 前端：使用Gambas GUI库开发，负责用户界面和交互。
- 后端：使用Gambas SQL库连接数据库，处理业务逻辑。
