In Jiangsu Province, the Southern Jiangsu Area Online Bookstore39。s Active Server Pages (ASP) technology. is built on the Common Language Runtime, meaning programmers can write code using any Microsoft .NET language. Microsoft SQL Server 2020 SQLServer 2020 will be soon reaching its fiveyear mark, which in terms of software lifecycle translates into fairly advanced maturity. While this is still far from retirement age, the name of its successor, SQL Server 2020, suggests that it might be time for you to start looking into what the new generation has to offer. The release of SQL Server 2020, originally introduced as Yukon, has already been postponed, but its current Beta 2 implementation (with several incremental Community Technical Previews expected before Beta 3 bees available early next year) brings promise of a timely RTM stage In this series of articles, we will look into functional highlights of the ne w incarnation of the Microsoft database management system, focusing on those that are likely to remain unchanged in the final product. . The .NET Framework is supports building and running the next generation of applications and XML Web services in the internal Windows .NET Framework is an integral Windows ponent that supports building and running the next generation of applications and Web services. The key ponents of the .NET Framework are the mon language runtime (CLR) and the .NET Framework class library, which includes , , Windows Forms, and Windows Presentation Foundation HYIT – GENETIC SINGAPORE COMPUTER SCHOOL GROUP 9 OBS For HYIT Page 13 BASIC KNOWLEDGE (WPF). The .NET Framework provides a managed execution environment, simplified development and deployment, and integration with a wide variety of programming languages. For a brief introduction to the architecture of the .NET Framework, see .NET Framework Conceptual Overview. For a discussion of .NET Framework version and its relationship to previous versions of the .NET Framework, see .NET Framework Architecture. Inter Information Services () Inter Information Services (IIS ) is Microsoft’s latest version of their web server. IIS has been included with Windows Server since Windows 2020 Server as a Windows Component and since Windows NT as an option. IIS is available with Windows Vista and Windows Server 2020, which is scheduled for release in Q1 2020. IIS has gone through a major overhaul and has been pletely redesigned from scratch. This has been done to make the most flexible and secure platform for web and application hosting. Based On B/S Architecture In the B / S system structure of the system, the user through the browser on the work to the distribution of many of the server request and then the server on the browser to process the request. The user information needed to return to the browser. B / S structure, simplify the work of the client and the client only need to configure a small number of clientside software. Server will assume more work and access to the database and application server implementation will be pleted. Browser making the request, while the other requests such as data processing, results are returned and dynamic web page generation, etc. all pleted by the Web Server. In fact , B / S architecture is to layer C / S structure of the transaction processing logic tasks from the client module to separate from the Web server is a separate ponent of its mandate to cover the floor, so that the client is alleviated, the load distribution to the Web server. This threetier architecture as shown : Threetier architecture Browse Web server Database HYIT – GENETIC SINGAPORE COMPUTER SCHOOL GROUP 9 OBS For HYIT Page 14 BASIC KNOWLEDGE This structure not only clients from the heavy burden and continue to improve the performance of its liberation of the requirements, but also the technical maintenance personnel from the heavy maintenance and upgrade work in earnest. As the client part of the transaction processing logic points to the function of the server to the client all of a sudden, slim, a lot, no longer responsible for dealing with plex puting and data access to key services, for display only part of the program is no longer so maintenance personnel maintenance of shuttling between each client, but to focus on functional update of the server program. This threetier structure in between the layers are independent of any level of change will not affect the functions of other layers. AJAX AJAX is Asynchronous JavaScript and XML (asynchronous JavaScript and XML), Ajax is a group of interrelated web development techniques used for creating interactive web applications. A primary characteristic is the increased responsiveness and interactivity of web pages achieved by exchanging small amounts of data with the server behind the scenes so that entire web pages do not have to be reloaded each time there is a need to fetch data from the server. This is intended to increase the web page39。 it includes such singleinheritance, interfaces, and almost the same syntax to Java and piled into the intermediate code and then run the process. But C and Java have very different, it draws on a feature of Delphi, and COM (ponent object model) is directly integrated and it is the Microsoft .NET Framework on a Windows work. C is a secure, stable, simple, elegant, by c and c++ derived objectoriented programming language. C , a bination of simple Visual manipulation VB and c++ high running efficiency, with its powerful operational capabilities, an elegant syntax style, innovative language features and convenient ponentoriented programming support has bee the preferred language HYIT – GENETIC SINGAPORE COMPUTER SCHOOL GROUP 9 OBS For HYIT Page 12 BASIC KNOWLEDGE of .NET developme
