Entity Framework Design First

A small mobile phone application, but all-encompassing, integration of this complex information content or functional logic. To let users get the best experience in the use, quickly grasp the application of the framework structure, the navigation design is an important link. The navigation of mobile apps is similar to the role of signposts or maps in the real world. It is the virtual framework of the application software, which has the function of indicating identity and recognizing the user. For example, as a signpost, navigation can be in use, locate where the user is currently, to highlight the current view of the user important features, tell users where to go, in different views and areas quickly cut ...

Uidesigner is the Tencent user research and experience Design Department (CDC) design of a design software, to create a unified platform for designers and team collaboration platform design tools, after 1.0 and 2.0 version of the experience of precipitation, we decided to 3.0 version of the new architecture design. The development of a software system, the early stage of the architecture design bearing the entire software design ideas and key decisions, can be said to be the most important. According to software architecture design ideas, focus on segmentation and interaction, good architecture must make each of the concerns separated from each other. We have the most basic need ...

The intermediary transaction SEO diagnose Taobao guest Cloud host Technology Hall recently some difficult to suppress the brain itch itch, reading and the desire of the code word is also increasing, but by the time energy and so on absolute objective factor limit, have to maintain a week a translation frequency, feel how many have so little frustration and helpless. About this article, actually hesitated for a long time in the title. This is the 15th chapter of the new book a Practical Guide to web app success; The theme should obviously be in the Web application, but this chapter alone ...

Absrtact: Self-control is the strongest instinct. Shaw's top design was originally a system engineering concept. That is, assuming you need to complete a major project, you have to use a variety of systems theory, you need to start from the overall, the project's self-control is the strongest instinct. Bernard Shaw's "Top Design" was originally a concept of system engineering. That is, if you need to complete a major project, then you have to use a variety of systems theory, you need to start from the overall level of the project, the elements of the overall consideration. So from the concept ...

In the past, we have introduced some principles of software development, such as the 10 commandments of high quality code and the UNIX design principles described in the UNIX legend (next article). I believe that you can learn from middle school some knowledge of design principles, as I said in the "How Do I Recruit procedures", a good programmer usually consists of its operational skills, knowledge level, experience level and ability four aspects. Here I would like to talk about some of the principles of design, I think these things belong to the long-term experience summed up knowledge. These principles should be understood by every programmer. But...

This series of articles is a learning record about the fundamentals of azure services development, and because of time constraints, the process of wishing to discuss and explore yourself is from scratch, to be able to develop basic programming for azure services. There may be a very deep topic relative to each topic, and I would like to have time to do it through other articles. 　　The positioning of this series is basically positioning, take 20-30 minutes, download the code first, follow the article, run to get the relevant experience. The previous article is about Azure queue storage, this is about ...

Hadoop is more suitable for solving big data problems, and relies heavily on its big data storage system, namely HDFS and big data processing system. For MapReduce, we know a few questions.

This article is my second time reading Hadoop 0.20.2 notes, encountered many problems in the reading process, and ultimately through a variety of ways to solve most of the. 　　Hadoop the whole system is well designed, the source code is worth learning distributed students read, will be all notes one by one post, hope to facilitate reading Hadoop source code, less detours. 1 serialization core Technology The objectwritable in 0.20.2 version Hadoop supports the following types of data format serialization: Data type examples say ...

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 book begins with the origins of Hadoop, and integrates theory and practice to introduce Hadoop as an ideal tool for high-performance processing of massive datasets. The book consists of 16 chapters, 3 appendices, covering topics including: Haddoop;mapreduce;hadoop Distributed file system; Hadoop I/O, MapReduce application Open ...

The distributed computing technology proposed by Google makes it easy for developers to develop global application services, and cloud computing technology automates the management of communication, task allocation, and distributed storage among a large number of standardized (heterogeneous) computers. 　　The cloud comes from a decentralized, parallel operation, but better than the grid. Data computing cloud technology can be considered as a sub-set of grid technology, both of which are designed to hide the complexity of the system, so that users need to use it without knowing how the system works inside. The parties follow up with Google to promote cloud services, but the definition is different ...
