Network Diagram - Dynamiclly Built


I'm looking for some feedback and ideas on a new system I've just been assigned...

I need to create a web app (C#) that will build a network diagram, have all of the components in a DB (servers, switches, UPS, etc) and have the app dynamiclly build it with relationships graphically.  And be able to click on a particular item, view its details and change its info.  Obviously a standard data driven gridview would not work for this...

Has anyone ever built anything like this or know of an addon, 3rd party component or anything that would work?

An Entity Relationship Diagram Example

An Entity Relationship Diagram conveys a lot of information with a very concise notation. The important part to keep in mind is to limit what you're reading using the following technique:

Choose two entities (e.g. Company and Employee)
Pick one that you're interested in (e.g. how a single Company relates to employees)
Read the notation on the second entity (e.g. the crow's feet with the O above it next to the Employee entity).

Creating your SharePoint Governance Plan

One of the most common questions that I get from prospects as I'm talking to them about the creation of a governance plan and process is what does it look like. In other words, there are materials available which describe what should be in a governance plan but there isn't a ton of guidance on what the process of creating a governance plan and process are.

Creating Paging for a Repeater Control

A common question is "How do I implement paging within a Repeater?" Although the beauty of the Repeater control is its flexibility, you're on your own for building most functions. ASP.NET 2.0 has included some new controls that provide paging, as does the DataGrid in ASP.NET 1.1. However, this tip shows you how to roll your own paging for a simple data viewer.

Creating an AJAX Repeater in ASP.NET MVC

The "TaskList" is a tried an true example of the most basic thing that you can do in any framework. Unfortunately, I had some problems finding a really good example of all the steps necessary to get a task list to work in ASP.NET MVC 1.0.

Creating a Generic Entity Framework 4.0 Repository

With .NET 4.0 right around the corner, I thought it would be cool to download Visual Studio 2010 beta 2 and start playing around with the next release of Entity Framework.

The initial release of Entity Framework came with a great deal of criticism. To make matters worse, there was a large uproar when it was rumored that Microsoft would be abandoning LINQ to SQL, in favor of Entity Framework. This was because, at the time, many developers felt Entity Framework was an inferior technology to LINQ to SQL. To set things right, Microsoft proactively moved forward with improving Entity Framework, in time for the 4.0 release of the .NET Framework. This is good news because my initial impressions, so far, have been nothing but positive.

UML Diagram Types

UML provides a number of diagram types as a mechanism for entering model elements into the model and showing overlapping sets of models elements and their relationships. UML does not specify what diagrams should be created or what they should contain, only what they can contain and the rules for connecting the elements. The diagram types include:

UML Diagram Types - 2

Further diagram types include:

Activity Diagrams - a generic flow chart used much in business modelling and sometimes in use case modelling to indicate the overall flow of the use case. This diagram type replaces the need for dataflow diagrams but is not a main diagram type for the purposes of analysis and design.

Use Case Diagram

The use case diagram shows the functionality of the system from an outside-in viewpoint.

Actors (stick men) are anything outside the system that interacts with the system.

Creating Sites/Lists/List Items under Current User Context in SharePoint By Using SPUserToken
