Application Design Diagramming Techniques-Part-II

component diagrams 

A component diagram is used to indicate the components (or code packages) that will be created for the application. A component is made up of logically related classes grouped together in a single deployable unit (consider them the DLLs or Web services).

The components are represented by the rectangles that include the two smaller rectangles on their left, as depicted below.



Each component name is preceded with text, indicating its logical layer, and then two colons. This text represents the components package.

The outer boxes that surround the components are called nodes.

All this is demonstrated in the figure below.



Class Diagrams is another diagram that can be created easily using Visual Studio and id the most commonly used diagram and would not be covered here.

Next post will cover Sequence Diagram.

Till next we connect……

Happy Learning.

Asp.Net 4.0: An Overview-Part-III

This is the last post in the series which will explore the following new features of ASP.Net 4.0  Performance Monitoring for Individual Applications in a Single Worker Process Web.config File Refactoring Permanently Redirecting a Page Expanding the Range of Allowable URLs Performance Monitoring for Individual Applications in a Single Worker Process It is a common practice to host multiple ASP.NET applications in a single worker process, In order to increase the number of Web sites that can be hosted on a single server. This practice results in difficulties for server administrators to identify an individual application that is experiencing problems. ASP.NET 4 introduces new resource-monitoring functionality introduced by the CLR. To enable this functionality, following XML configuration snippet is added to the aspnet.config configuration file.(This file is located in the directory where the .NET Framework is installed ) <?xml version="1.0" encoding="UTF-8...

WCF..Why Communication Foundation?

WCF (Basics..for building effective Services) WCF:  Windows Communication Foundation It includes a collection of of .NET distributed technologies that have existed for long , but never got grouped under one name. WCF can be considered as collection of the following technologies. Web Services(ASMX) NET Enterprise Services MSMQ .NET Remoting Code written in WCF can interact across components, applications and systems. WCF is in accordance with SOA (Service Oriented Architecture). Following Sections provide the details of these ABCs. Addresses In WCF, every service has a unique address. The address provides two important elements A)     Location of the service B)      Transport protocol or transport schema used to communicate with the service.  The location indicates the name of the target machine, site, or network; a communication port, pipe, or queue; and an optional specific path or URI. WCF supports th...

WCF-REST Services-Part-II

HOW REST is implemented in WCF Part-I of the series explored the REST conceptually and this post will explore how REST is implemented in WCF. For REST implementation in WCF, 2 new attributes namely WebGetAttribute and WebInvokeAttribute are introduced in WCF along with a URI template mechanism that enables you to declare the URI and verb to which each method is going to respond. The infrastructure comes in the form of a binding ( WebHttpBinding ) and a behavior ( WebHttpBehavior ) that provide the correct networking stack for using REST. Also, there is some hosting infrastructure help from a custom Service¬Host ( WebServiceHost ) and a ServiceHostFactory ( WebServiceHostFactory ). How WCF Routes messages WCF routes network messages to methods on instances of the classes defined as implementations of the service. Default behavior ( Dispatching ) for WCF is to do this routing based on the concept of action. For this dispatching to work, an action needs to be present in ev...
