Designing A Database Steps

Today has entered the web2.0 high-speed development of the internet era, a variety of Internet Web applications have sprung up. So how do you develop a good Web application as a Web developer? There is no simple answer to this question, even the educational institutions may not be able to know clearly. So, like most web developers in this field, we only learned this by doing experiments. No one tells us how to do it, we start by doing something for ourselves, learn how to develop Web applications in this ...

Introduction: Research and development typically use a typical scenario (scenarios) to understand what a system needs and how the system works. Unfortunately, while research and development have done so, he rarely archives in an effective form. The use case (use-cases) is a formal, formalized technique for capturing these scenarios. The use case is Jacobson in the software engineering of the image object, but he is actually independent of the surface object. Use cases are an effective way to gain business process and system requirements. And the technology itself is very simple and easy to learn. Make the demand accessible ...

This paper is an excerpt from the book "The Authoritative Guide to Hadoop", published by Tsinghua University Press, which is the author of Tom White, the School of Data Science and engineering, East China Normal University.

This paper is translated by Lu Bo, author of the Graduate School of Design, Jiangnan University, Anastasios Karafillis, to view the original although navigation is a vital part of the user experience, it is only one way to achieve the goal (find content). Users have different expectations of content and navigation, content should be unique, amazing or exciting, and navigation should be as simple and predictable as possible. The articles in this series are divided into two parts, with four steps to simplify navigation effectively. By analyzing the type and number of content, select and carefully design the correct type of navigation menu. Create a ...

If you have not yet turned to cloud services, the consideration should be implemented, and there should be no doubt about that. It is expected that by 2015, the global cloud computing market will reach $121 billion trillion, far exceeding 2010 years of 37.8 billion dollars. However, it is very hasty to join the cloud services, the pressure is there, without careful planning to implement may cause trouble in the future. Cloud projects can be complex for almost any organization, whether the project is a private cloud, a public cloud, or a mixed cloud. While your initial goal may be to create a cloud architecture that meets your current needs, the cloud services you build now will ...

Cloud computing model based on natural Cloud Tangmin Beijing (100876) e-mail:tangminbupt@gmail.com Abstract: In the network autonomy system such as Web Service, Design a system with better communication capability, robustness and security according to cloud computing model. The model is mainly composed of the quantity dynamic controllable sub middleware and the Unified management platform.

If your cloud service is closed or temporarily interrupted, what should you do to make the loss as low as possible? In February 2009, cloud service provider Coghead in a letter addressed to customers that "due to the impact of economic challenges", the company can no longer operate, will immediately terminate the Cloud-based development platform services. Subsequently, ERP giant SAP acquired Coghead's intellectual property, but no longer support this development platform, not only that, but also let the original Coghead customers in April 2009 3 ...

We believe that the goal-oriented design method consists of 4 p, i.e. process, pattern, principles, practices (processes, patterns, principles, practices), and I will discuss the first 3 p. Interaction design is generally a difficult and messy task, and interaction designers are often asked to imagine and define in a tight schedule a possible use of the latest technology, and no one has seen, we must have a deep understanding of the complex areas of products, must balance the competitive priorities, Must understand the constraints of the technology used and the machine ...
