摘要: 了其然，知其用，研其究，發(fā)其思
了其然：對最近新出現(xiàn)的理念技術(shù)能夠有所了解，簡單知道其可以解決什么問題，分析一下是否最近自己所需要應(yīng)用，或可被更好的利用。
知其用：知道如何應(yīng)用這門新技術(shù)。簡單的應(yīng)用一般花費不少時間，但是想復(fù)雜的應(yīng)用，需要耗費的時間和精力可就多了。如果把握不好，盲目的應(yīng)用和學(xué)習(xí)，會浪費不少時間。
研其究：對新技術(shù)新理念研究其深層次的原理，框架，結(jié)構(gòu)。
發(fā)其思：這是最難的一層，首先需要有研其究的基礎(chǔ)，這本身就是一個高難度的事情。而研究之后，能夠發(fā)散思維，擴充或本土化改造，則更是艱巨的事情。

調(diào)整PCTFREE和PCTUSED等存儲參數(shù)優(yōu)化插入、更新或者刪除等操作；
