The knowledge about Oracle database implementation plans is what we will introduce in this article. We first introduce the concept of implementation plans, and then give examples of two implementation plans, finally, we introduced the form of the Oracle optimizer and the purpose of the plan. Let's take a look at this part.What is a strong plan?The so-called implementation of the plan, we hope that, even for a query task, make a detailed plan on how to end the task. For example, if I want to go t

DWR is a framework. Simply put, it can directly call Java methods in Javascript without having to write a lot of JavaScript code. It is implemented based on Ajax and can achieve no refreshing effect. There are many DWR examples on the Internet, but most of them are just some method calls. This article only introduces DWR at the usage level and does not involve more technologies and designs, the objective is to allow beginners to quickly learn how various Java methods are called in JavaScript.
