Design Principle

Design and implementation of e-mail security service system based on cloud computing Dai Jin Liu Shang Haoyu current e-mail Security scanning software is being widely used, with the increase of the number of users and the flow of the system, the traditional tight-coupled synchronous processing IMHS system has many problems, such as the overall efficiency, robustness, maintainability and extensibility. Aiming at the system bottleneck under the pressure of mass user, the design principle of "loose coupling, asynchronous, stateless" is established, and the design and implementation of cloud computing and service Oriented Architecture (SOA) technology is designed and implemented.

Content relevance, as we all know, is the core of keyword rankings. We review the original design principle of the search engine, that is, through the keyword and the content of the article to determine whether the article is the most relevant, that is, we often say that the keyword density, the higher the density, our keyword ranking the better. But here again involved a problem, which is the higher the keyword density is easy, we can accumulate keywords. This is not the guarantee of the density of the keyword? So search engine to prevent this effect of fair cheating behavior, it took a filter calculation program. If...

There are countless ideas in mind when we start designing a project. Is to do a strong visual impact, brilliant eye-catching style? Or retro collage style? Or the most in the current minimalist design, so that the focus of eye-catching jump in the screen above? As designers, we always collect a great variety of good ideas, good design solutions. But how can you find the best idea for the upcoming project in so many ideas accumulated or http://www.aliyun.com/zixun/aggregation/8936.ht ...

Nxlog is a modular, multithreaded, high-performance Log management solution that supports multiple platforms. Its concept resembles Syslog-ng and Rsyslog. But not limited to use in Unix/syslog. Nxlog 1.2.457 This is the first public release version. A http://www.aliyun.com/zixun/aggregation/8912.html "> Design principle of Syslog-ng is to build better message filtering granularity. ...
