三
三层体系结构 我们经常会看到许多应聘者在简历上写着“精通数据库编程”的字样，也经常会在招聘网站上看到软件公司的招聘要求中某一项为“精通数据库编程”。于是这些应聘者去这些软件公司面试，于是我们看到了许多“精通”者落选的现象。 一些程序员在设计数据库应用时，通常会采用数据控件绑定的方法实现。用鼠标拉几个控件，再用鼠标设置几个属性，连键盘都不用动，就完成了一个数据库应用的开发！当然，这的确是一种快速的数据库应用开发方式，但快速并不意味着精通。 对于大型的数据库应用系统，或是拥有众多客户端的应用系统，我们需要另外一种“精通”，这就是几乎每个程序员都听说过的“三层体系结构”。-three-tier architecture we often see many candidates in the curriculum vitae reads "proficient Database Programming" message, often in recruitment website software companies see the recruitment of a request for a "proficient database programming." So these candidates to interview these software companies, so we see a lot of "proficient" who lost the phenomenon. Some programmers in the design database applications, using data normally bind to the control method. Pull a few mouse control, and then attribute several mouse settings, and even keyboards do not have to move, it completed a database application development! Of course, this is really a fast database application devel

这个例子是由两个独立的项目/应用程序的功能。eir_a
This example consists of two separate projects/applications eir_a for the role A device and eir_b for the role B device and uses the Connection library.
* eir_a searches for devices and then displays the information on the devices found.
* eir_b makes the device visible and responds to Bluetooth 2.1 Extended Inquiry Response (EIR) requests.
This ReadMe is not intended to describe procedures that are covered in the xIDE user guide such as building projects in xIDE etc.

JavaScript主要是针对客服端编程，但是，这个说法是不对的。JavaScript是一门独立的语言，像C一样可以做任何事；但是，我这用JavaScript做客户端辅佐功能。-JavaScript is mainly aimed at customer-side programming, but this view is wrong. JavaScript is a separate language, like C can still do anything however, I have to use JavaScript to do client-side adjuvant function.
