In the day-to-day development of many new colleagues do not quite understand how to connect Oracle server, here I do an Oracle client common way of brief:
In fact, there are many ways to connect Oracle services such as: Native, PL,,
Where Native for Oracle is very simple to do the small amount of data or the data is simple, if you encounter large data, Native for Oracle performance will be very poor, this I have tested.
Here is a note of your usual ways:

Asynchronous JavaScript and XML (AJAX) are new ways to build rich Web applications using native browser technology. JavaScript has done a good job for developers who write complex applications that require certain types of "active" user interfaces. However, JavaScript is difficult to encode, debug, migrate, and maintain. Using AJAX toolkits helps minimize many of the common problems with JavaScript and Ajax. The excellent AJAX Toolkit provides a reusable set of widgets, frameworks
