ASP.NET Layers
ASP.NET is broken down into 3 layers:
The ASP.NET Application, as the base layer, with ASP.NET Pages and
ASP.NET Web Services sitting on top of the application. The application represents the
entire solution, with ASP.NET Pages representing the user interface, and Web Services
exposing selected functionality of the application.
Introducing
Web Forms
Web Forms is an ASP.NET technology used on the
server to dynamically generate web pages. These pages utilize server-based programmable
user interfaces called Web Forms controls that encapsulate common functionality.
ASP.NET Web Forms Framework has been specifically
designed to address a number of key deficiencies with the previous model. In particular:
 Reusability of UI controls, which can encapsulate
common functionality and reduce the coding.
Allow for creating all application logic on the server,
eliminating the need to explicitly code for browser differences.
The ability for developers and designers to work
independently -- non-“spaghetti code” – fashion.
ASP.NET. Web Form Pages are
text files with a .aspx filename extension.
Introducing Web Services
A Web Service is a programmable application
component that provides a particular functionality, such as a business logic, that is
accessible to any number of potentially disparate systems via standard Web protocols such
as HTTP, XML, SOAP, and UDDI. ASP.NET. Web Form Pages are text files with a .asmx filename
extension.
Web Services enable the exchange of data in business to consumer (b2c) and business to
business (b2b) scenarios, providing access to remotely distributed business applications
that can be manipulated from a variety of Internet-enabled clients and devices.
A Web Service can be used either internally by a
single application or exposed externally over the Internet for use by any number of
applications. Because it is accessible through a standard interface, a Web Service allows
disparate systems to work together as a single Web application.
Besides technology that allows developers to
create Web Services, Microsoft .NET Framework provides a sophisticated set of tools and
code to consume, or access as a client, these Web Services. Because Web Services are based
on open protocols such as the Simple Object Access Protocol (SOAP) and HTTP, this client
technology can also be used to consume non-ASP.NET. Web Services. Of course, the level of
integration between ASP.NET. Web Services and the client technology is extremely high.
Summary:
ASP.NET. is a powerful, strongly typed language,
so developers can have a choice of language which best suits them. A vast set of server
controls enables quick development time, and easily customizable, browser-safe output.
Deploying is no more a problem with XCOPY on our way which makes it easy and simple. Both
ASP and ASP.NET. can run in parallel, which reduces the need for new hardware dedicated to
ASP.NET. |
