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...

Covariance and Contravariance-General Discussion

If you have just started the exploration of .Net Framework 4.0, two terms namely Covariance and Contravariance might have been heard. The concept that these terms encapsulate are used by most developer almost daily, however there has never been any botheration about the terminologies. Now, what actually these terms mean and how are these going to affect us as a developer, if we dive in to the details. The simple answer is it’s always good to know your tools before actually using them. Enough philosophy, let’s get to the business. Starting the discussion let me reiterate that in addition to Covariance and Contravariance, there is another terminology, Invariance. I’ll by start here by diving into the details of Invariance and then proceed further. Invariance: Invariance can be better understood by considering the types in .Net.>net has basically two type, value-types and reference-types. Value types (int, double etc) are invariant i.e. the types can’t be interchanged either ...
