推荐答案

RAD代表快速的应用程序设计.通常，这意味着假装VB6之类的语言，以便非程序员可以显示表格.控制库是一个完全有效的概念.想一想.您希望控件能够做很多很棒的事情，但是您没有时间编写它.或者，换句话说:您可以自己编写它，这意味着所有开发时间都需要由一个客户支付.或者，公司可以编写这些控件，然后一遍又一遍地出售它们，这意味着它们被广泛使用，经过了良好的测试，并以仅支付内部开发人员编写该控件费用的一小部分出售.

我最近买了一个PDF库.早上，我拥有了想要的PDF功能，而花费的时间却比花在编写它上的时间还少，而这花了我数周的时间.

RAD stands for rapid application design. Normally, that means pretend languages like VB6 so non programmers can make a form appear. Control libraries are a perfectly valid concept. Think about it. You''d like your control to do a ton of cool stuff, but you don''t have the time to write it. OR, to put it another way: you could write it for yourself, which means all the dev time needs to be paid for by one client. Or a company can write these controls, sell them over and over, which means they are widely used, well tested, and sold for a fraction of the cost of paying an in house developer to write it.

I bought a PDF library recently. I had the PDF functionality I wanted in a morning, for less than the cost of my time to write it, which would have taken weeks to do.
