In the previous section, "WCF Distributed Framework Basics" we introduced the concept and communication framework model of WCF services, and gave the implementation code of WCF programs based on custom managed services. Consider the managed hosting service configuration and the Client Add reference in the WCF Distributed development project. Two links are the most error-prone. For most people who want to learn about WCF distributed development, it is difficult to successfully develop, configure, and deploy your first WCF service. A lot of information introduces the basic concepts of WCF. But ...

By clearly defining the relevant concepts of large data, enterprises can plan their own data system correctly, and locate the traditional technology and new technical methods appropriately. With the rapid development of it technology and the emergence of new technologies, the industry has generally confused many basic concepts. This is also the case in today's most popular large data fields. The concepts of structured data and unstructured data are frequently cited, but the parties are often diverging. The confusion of the concept of data has greatly influenced the enterprise to plan the data system clearly and correctly. The author of this article from the actual work ...

Looking back on our recent history of technology development, it is clear that since distributed computing and its related technologies (such as grid computing and SOA) have been widely adopted, the cloud computing movement has emerged. Although cloud computing has become a new technology, there are many questions about this new technology. The 1th installment of this series will outline cloud computing, then analyze the various layers of the cloud, introduce different cloud types and their pros and cons, and explain why cloud computing campaigns are for enterprise development ...

We introduce the theory and basic concept of market capitalization management law, this method is usually a publicly listed company for the operation of the target of actual combat operations, but put aside the listing of goodwill, intangible assets premium and liquidity premium, the value of the enterprise and whether the listing relationship is not small, mainly to see its market share, innovative ability and cash flow. In fact, unlisted companies have the same market value, especially after their size has become bigger, the difference is that the unlisted company liquidity is not listed companies, the market to participate in the transaction of less than the main body, it is not easy to find a suitable opponent disk, transaction costs high. China's largest ...
