1.请问魔方网表是源码无代码开发还是低代码开发？
2.jsp登陆界面源代码
请问魔方网表是无代码开发还是低代码开发？
无代码是低代码的一个细分，指没有编程扩展能力或者编程扩展能力很弱的源码低代码产品。
按照Gartner的源码观点，Appian属于典型无代码，源码医院php网站源码而Outsystems是源码低代码的代表。两者的源码实现LSTM源码开发体验很像，做简单应用时的源码开发效率差距不大，但是源码后者的编程接口非常全面，前者几乎没有。源码这就决定了Outsystems可以无限制的源码用来开发更复杂的系统，而Appian通常用于开发营销和客户支持用APP。源码
这里的源码编程接口通常包含前端样式（CSS）、页面交互（JavaScript）、源码成交分布源码服务端业务逻辑（Java/C#等）和数据处理（SQL函数、源码存储过程等）。源码这些接口都是小拼车源码为保障系统集成能力而生的。对比国内上市的典型低代码开发产品的编程扩展能力，如活字格、PowerApps等，点卡源码系统魔方网表应该属于无代码开发产品。
