My recent project does not allowProgramWrite the SQL statementCodeBut must be implemented using a stored procedure, even a SELECT statement. I think this is more advantageous than harm. Of course, my project is not very complex, and there are about two hundred stored procedures.In my opinion, the advantages of not allowing SQL statements in Code are as follows:1. avoid confusion. Changes in requirements will always lead to data changes. changing data

The principle of DWR:One, what is DWR?DWR: (Direct Web Remoting) is an open-source class library that helps developers develop Web sites that contain Ajax technology. It allows code (JavaScript) in the browser to use Java functions running on the WEB server as if it were in the browser .It consists of two main parts:A. Allow JavaScript to get data from a servlet (small application) that adheres to Ajax principles on the Web server.B. Its JavaScript library can help Web site developers easily use

In the design of the database, there are paradigms and anti-paradigm of stress, summarized below. Advantages of the paradigm:1) The normalized database is updated more quickly;2) After normalization, only a small number of duplicate data, only need to modify less data;3) The normalized table is smaller and can be executed in memory;4) Less redundant data, requiring fewer distinct or group by statements when querying. Disadvantages of the paradigm:5) A

Enumerating the development advantages of the Yii 2 framework of PHP, the YII framework When the YII framework is still in the RC (candidate) phase, we have reported it, when it has just reached its full candidate version stage, (now it has released the official version) we feel it's time to revisit this topic: the reason for choosing the YII framework. 1. Easy to install For web developers, time is money, and no one wants to spend valuable time in a

The advantages are: 1. You can define multiple separators at once. When the function is executed, it is cut by a single delimiter rather than by the entire delimiter, while the explode is cut by the entire separator string. As a result, explode can be cut in Chinese, and strtok is not, will be garbled. 2. When using the while or for mate Strtok () traversal, you can change the delimiter at any time, or you can break out of the cut at any time. Example

Advantages of DIV+CSS Website design The industry is more and more concerned about the standardization of DIV+CSS design, to major portals, small to countless personal sites, under the influence of DIV+CSS standardization, web designers have made this requirement as an industry standard. So what is the DIV+CSS standard? What are the benefits of DIV+CSS's standardized design? Div Full name division means to "distinguish" the use of Div method with the

In the financial service industry, a controversial topic in the field of security and rule compliance is "encryption technology stores data and the encryption of transmitted data) and the confrontation between marking technology ". Because Rules comply with requirements such as the Payment Card Industry Data Security Standard pci dss) and FFIEC information security inspection requirements include requirements for encryption and data protection, enterprises are trying to find the best way to prot

Technical advantages of media-based Encryption Many requirements clearly require media encryption technology as the preferred method. In stark contrast to media encryption, both host-based and device-based encryption methods are difficult to achieve the purpose of tape media encryption. The host-based method requires important management expenses and may occupy valuable resources of the host. The device-based encryption method may make the system unab

Advantages and disadvantages of a responsive website Advantages: I. Reduce workload 1. Only one copy of the website, design, code, and content is required. 2. The extra work is only a JS script and CSS style change. 2. Save time. In the Internet field, time is the most important. Sometimes when a project is released late, it will lose the market. 3. Each device can be properly designed. Different devi

Advantages and disadvantages of MATLABMATLAB is a set of powerful engineering calculation software, which is widely used in automatic control, mechanical design, fluid mechanics and mathematical statistics and other engineering fields. By using the toolbox provided by MATLAB, engineers can efficiently solve complex engineering problems, and can simulate the system dynamically and display the numerical results with powerful graphical functions.

Comparison of the advantages of the website construction programming languages, Asp, Php, Jsp, and Asp. Net [Qingcloud technology Editor] Many SOHOER wants to have their own website, but they do not know anything about website construction, or they know nothing about it. today, I will talk about the difference in programming. I believe many people have come across some companies that say php is better than Asp and Asp. net is better, or Asp is better

I. Advantages of QT: 1. cross-platform2. the signal-slot mechanism is too elegant. Compared with MFC, its non-Form class also supports this mechanism. This designer's idea is admirable, and because its non-Form class also supports this mechanism, so many of its usage makes people feel bright, such as the use of qtimerevent, whether it is a form or not, can support timer, this is much more flexible than MFC3. Easy to use. Many mechanisms are similar to

Every time I play games, I will be seen by the supervisor. Zhu doesn't like his staff when they go to work. In this cas

Advantages and disadvantages of blocking and non-blocking Io packages in Java The cornerstone behind NiO design: the reactor model, which is used for event Multi-Channel Separation and dispatching of the architecture model. Reactor: an architecture pattern used for event Multi-Channel Separation and allocation Generally, a file or device specified by a file descriptor can work in two ways: blocking and non-blocking. Blocking means that when you try to

I. Why should I create an index (advantage )?This is because creating an index can greatly improve the system performance.First, you can create a unique index to ensure the uniqueness of each row of data in the database table.Second, it can greatly speed up data retrieval, which is also the main reason for creating an index.Third, it can accelerate the connection between tables, especially in achieving Data Reference integrity.Fourth, when you use grouping and sorting clauses to retrieve data, y
