## 可行性研究
|
|
|
|
|
|
|
|
|
|
|
|
### 1. 技术可行性：
|
|
|
|
|
|
|
|
|
|
|
|
a.开发系统采用
|
|
|
|
|
|
|
|
|
|
|
|
前端：Vue3
|
|
|
|
|
|
|
|
|
|
|
|
后端：SpringBoot2 + MybitsPlus + Maven
|
|
|
|
|
|
|
|
|
|
|
|
数据库：mysql8.0，预期能够准确开发完成系统。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
b. 开发人员经过两年半的专业学习，拥有一定的经验和扎实的基础
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 2. 经济可行性：
|
|
|
|
|
|
|
|
|
|
|
|
该系统规模较小，不涉及经济的投入（有也会很少)，所以将不会有经济上的风险。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 3. 运行可行性：
|
|
|
|
|
|
|
|
|
|
|
|
由于商品订货系统是相对独立的系统，除了与操作系统交互外，与其他软件的关系不大，所以发生冲突的概率较低。万一发生不能协调工作，为了本系统的安全，将对外来系统做一定限制，严重的将采取禁用策略。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 4. 法律可行性：
|
|
|
|
|
|
|
|
|
|
|
|
该系统在超市、百货商场等类似场所使用，用于记录商品的订货信息，其中不会添加获取用户密码等受法律保护的信息的操作。该系统只会保留用户进货日期和时间，以及供应商和商品等数据，以便用户日后核对，或者供其他一些有权限的人或部门调查。
