on standardized and widely supported technology, do not need to download plug-ins or small programs. Disadvantages: 1, Ajax killed the back button, that is, the browser backward mechanism of the damage. 2, there are certain security issues. 3, the search engine support is weaker. 4, the failure of the program's abnormal mechanism. 5, can not use the URL direct access. The above is a small set to introduce the AJAX working principles and

complex applications. The monolithic architecture is more suitable for lightweight, simple applications. If you use it to develop complex applications, it's really bad. The MicroServices architecture model can be used to build complex applications, and of course, this architectural model has its own shortcomings and challenges. In a subsequent blog, I'll delve into the microservices architecture pattern and discuss strategies such as service discovery, service deployment choices, and how to bre

A Disadvantages: 1. Portability is the biggest drawback of stored procedures and triggers. 2, occupy the server side too many resources, to the server caused a lot of pressure 3, can not do DDL. 4, the trigger scheduling error is difficult, and the data is easily inconsistent, late maintenance inconvenient. Advantages: 1, precompiled, has been optimized, high efficiency. Avoids the inefficiency of SQL st

Since I have not been familiar with Oracle, I have not answered this question. I have checked the information and summarized it as follows. I have the opportunity to study oracle in the future. I don't know how the written test is. I hope God didn't go to WC. Advantages and disadvantages of hot backup and cold backupA

too flexible in hibernate. When you use EB to implement the persistent layer, you will find that eb is too clumsy, so you have no choice at all, therefore, you don't have to spend any energy designing a solution, balancing the advantages and disadvantages of the solution, and worrying about which solution to choose, because only the only solution is in front of you. You can only do this, no choice. On the

, because the price of the server itself has the advantage, if you buy the server hosting fee is usually higher than our price a lot.If you buy a server alone and find the host alone not only the cost rise and once there is a problem, the first to determine the server and the network which is a problem, more shifting, renting our server, whether it is a server problem or network problems are our responsibility.Dongguan City, a network Technology Co., Ltd. is a professional engaged in server host

If you find out, just tell me.AdvantagesCompared to origami: prototypes run in native mode on the device, so they are much more responsive than origami live.You can use the camera, accelerometer, gyroscope and positioning function on your device. (Origami can use the camera on your Mac)DisadvantagesLike origami, if a complex prototype is made, running like a noodle soup is sticky.

The advantages and disadvantages of InnoDB and MyISAM for MySQL storage engine analysis bitsCN.com are as follows: ◆ Does your database have a foreign key? ◆ Do you need transaction support? ◆ Do you need full-text indexing? ◆ What query mode do you often use? ◆ How big is your data? Thinking about the above questions can help you find the right direction, but that is not absolute. If you need transaction

Currently, cloud computing has become a star word in our security work. The "sincere and united" style of work has brought unparalleled work efficiency to our security work. For a long time, the biggest dilemma of network HD lies in the shortage of transmission environments and storage. However, with the wide application of optical fiber, the problem of transmission lines has now seen the dawn of solutions. However, the lack of storage terminals has b
