I am planning to build a website for courses online, teachers can create their courses and put their exams, students can enroll, view courses and apply for exams ..
I am a bit confused, to build it with DDN or Drupal ? which is easier and more powerful ?
I have no problem with .NET C# or PHP, although I see C# more easy to code with,
what I need to know, which CMS is better for my case ?
Which CMS is more robust & complete ?
Thanks in advance.
Of course, either platform has its pros and cons. What you're looking at building is essentially a Learning Management System, or LMS. There are a few existing LMS solutions built specifically for DotNetNuke. They include Engage: Campus, NetLearn, and Accord.
I would tell you to go with which ever platform offers you the most features for managing this kind of content for the best return on your investment, and offers you the best comfort level. If you're familiar with .Net and are comfortable in that arena, then stick with DotNetNuke. Otherwise go with another platform. However, having nearly 8 years of experience in developing solutions with DotNetNuke, and 13+ overall in developing software solutions (including PHP-based ones), if I have a choice, I always go with DotNetNuke. (And not just because I am an employee for a year now.)
I find that DotNetNuke has the most stable builds and releases overall. It's security team and features are second to none. It's community and ecosystem is unrivaled. If you're looking for a pre-built solution for any kind of business problem, chances are that the 10,000+ extensions in the Store or Forge will get you up and running with less development time and less expense. The forge has free (open source) extensions, and the median price of a store extension is $89 (LMS's are quite more expensive though).
The eco-system also boasts over 800 known ISV's out there. So chances are, if you're looking for support, not only is there an official company to provide it and back you up when something goes wrong, there are numerous other options out there in terms of companies that specialize in DotNetNuke.
One last thing on the releases... DotNetNuke has a known roadmap, a frequent release cycle, and an outstanding reputation for backwards compatibility. Your extensions will continue to work on the platform as you upgrade to take advantage of the latest and greatest features added to the platform, usability updates, bug fixes, and security updates.
As a Sales Engineer at DNN Corp, I hear all kinds of use cases, and I see DotNetNuke used a lot in educational institutions. They all use it to varying degrees as not only a CMS, but also a LMS, social platform (even in schools), and more. Most schools are also standardized in some way on the Microsoft stack too, so integration is much more straight-forward using DotNetNuke.
I could go on, but this is as much time as I have to give you an informed response.
Based on what you are trying to build DotNetNuke will only really give you authentication and basic page creation out of the box. All those other elements will have to be custom coded in .NET.
If you use Drupal 7 you can build majority of that using CCK, Views and workflow without really having to do a ton of programming if you don't want to.
I have been doing DotNetNuke since 2003 and have developed tons of modules for it, including some publicly available at www.dnnspot.com
If I was in your shoes I would do Drupal, but I know both pretty well.
ACTUALLY - If 'I' was in your shoes I would do Ruby on Rails now ;) but ... Drupal would work pretty well and you could get alot if not all of this done without slinging much code. Drupal is crazy.
DNN is now built on C# but has always been on .NET. I'm in a similar position as I code in PHP and .NET and have used Drupal and have been working on DNN for the last 4 years. I find that Module Development in DNN is wonderful.
i hope that helps.
Full featured Learning Management Systems (LMS) require substantial development (man decades), especially if you want to support SCORM eLearning content. Both DNN and Drupal will offer you most of the add on functionality that you will need in addition to the LMS features - the ability to build web pages, rich text editors, etc.
I would evaluate the different the LMS available for each platform and make your choice based on how robust the LMS are. In addition, evaluate how easily the LMS integrates with add on modules such as forums, wikis, etc. Most of our clients select our LMS without any knowledge of the portal framework beneath it.
Based on these evaluation metrics I am confident that you will find the Interzoic Accord LMS running on DNN to be a superior choice.

I am planning to develop one website which should have following features
Database integration
online payment system
forum
I need suggestion for my following questions before I will proceed to develop my site.
Is there any any single development tool which can provide me one webserver + mysql database + user login + java-script support + webpage design + online payment system and forum and easy site maintenance ?
What best practice to start development of this type of project?
How much effort it need to maintain this type of project?
"database integration" isn't really a feature - it's the tool you use to deliver your features. A feature might be a shopping cart, or a product catalogue, or a structured navigation system, etc.
In order to talk to a database, you almost certainly need some back-end code to be running, and you need to be able to program.
Yes, there are frameworks/tools that accelerate this, but you do need to invest at least in the basics of learning how to code.
Alternatively, if what you really want is to build an online shop, sign up for a "software as a service" offering where all you have to do is configure the product.
Sounds like you could use a framework to do your project with. Take a look at http://www.drupal.org.
If you're including an online payment system then you need to ensure that it's high quality, developed by people who know how to properly secure such a system. You should also be looking for a solution that handles pretty much everything you need it to do or that allows you to plug in modules for additional functionality rather than modifying solid code. There are so many ways for a developer to foul up even the best designed system that it's best to just leave it alone unless you're fully up-to-speed on secure coding guidelines.
IF what you really need is a way to sell things, and content to manage, then what you're looking for is a shopping cart with content management capabilities. There are plenty of good ones out there, and you should Google them. We went with the AspDotnetStorefront because it suited our needs, and was PACB certified, but there are plenty of others out there. Shop around if this is the type of thing you're looking for.
That said, you can get a good framework that has shopping cart options, and also the ability to add/modify modules to provide functionality with DotNetNuke. There are a wide variety of pre-existing modules to choose from as well. And you certainly can't beat the price on the free version. Developing for it takes some getting used to (there's a learning code even for experienced .NET developers) but it's pretty flexible.
Edit - I realize I'm only offering .NET suggestions, but you didn't mention what development tools/language you are comfortable with, so I'm mentioning the ones I've worked with. There are good (some arguably better, some arguably worse) Java and PHP equivalents to the suggestions I'm offering as well.
I've used CakePHP on several projects in the past, and have more recently started using Ruby on Rails, but there's a new project I'm about to start that will require PHP. While refreshing myself on CakePHP I learned that there is a new framework called Lithium that is essentially what CakePHP 3 was going to be. It's being developed by a group of former core CakePHP devs.
I haven't found a whole lot of information about it since it's still under development status, but I was wondering if anyone knows (or has a link to) some information on what benefits it provides over CakePHP. Hopefully something a bit beyond the quick overview shown on the official site. I'm trying to decide whether to use CakePHP for my upcoming PHP project or to wait a bit for Lithium to release a non-development version and try that out.
Hope this answer doesn't come too late, (and as the lead developer of Lithium, I'm a little biased :-)), but I will say that this is a hard thing to sum up. Lithium is the culmination of over 4 years' experience building and working with CakePHP, and while it retains many of the same designs and conventions, it was built to correct CakePHP's many architectural flaws.
In brief:
Framework features are grouped into loosely-coupled "packages" that are easy to use independently.
Tangentially, everything in Lithium is a "library", including your application, and Lithium itself. Support for integrating 3rd-party libraries is vastly improved, and all classes are namespaced, so you can finally have a model called File.
It is very easy to swap out core classes with your own custom implementations.
Lithium has a unique "filter" system that allows you to hook into many methods in the framework, which allows you to design your applications in an aspect-oriented fashion. These features work together to make Lithium the most flexible PHP framework, bar none.
Everything is lazy-loaded, and the architecture has been designed for maximum performance.
Lithium supports the latest tech, especially new databases like CouchDB and MongoDB.
I could go on for a while, but that's the gist of it. If you have any more questions, feel free to drop by #li3 on Freenode, and someone will happily give you a tour.
There is very little documentation so far. Here are some brand-new slides from gwoo though, that might be a good overview:

See the Lithium about page in their wiki. It lists all the features it will provide.

Currently as my job profile i am more working on asp .net application but i also wanted to have my hands on silverlight application. so, i just decided to build one silverlight 4 application in my spare time and on weekends.
We are having a team of around 4 people. We also tried for commercial application but as we can only develop it in our available time we can not commit on timeline as well as we people are new to SL, so first we need to learn concept and implement it. (Though we know the concept of binding, commanding,templates etc.)
Now i just thought to work on project like creating a social networking site in SL 4
having facilities like forum, blogs, calander, task, dashboard etc.
We want to use features like .Net RIA Service, Entity Framework, MVVM pattern, SL 4.
Objective here is to learn new concepts as well as to get some good project experince in silverlight.
Now,
what you people suggest is it a good idea ?
If yes then the project selected is correct or you suggest some other project ?
Any pattern or technology related suggestions ?
This is quite a vague set of questions but I'll attempt to give my 2 pennies worth of advice.
As a learning project this is as good an idea as any to get going with. As a commercial idea it probably isn't such a good one due to there not being any niche in your product. It has all already been done, and been done successfully by the likes of Facebook and Twitter. Developing any kind of social media site is incredibly difficult as the market is already fairly saturated. As I said though, as a learning project it's quite nice as you can just borrow concepts and ideas from other sites and you can concentrate on you main goals of gaining knowledge in the various technologies.
Whatever you decide to do I'd say split the project up into much smaller components rather than having the end goal in sight. Try to take more of an agile approach by setting yourself 2-3 week targets. It should help keep the momentum going. My experience is that learning projects tend to die a death as people get bored of the concept and lose motivation to do it. By keeping the tasks small you get to see small results often. This should help keep you motivated as you move from requirement to requirement.
Personally I think setting up personal projects and goals like this are a great way of learning new technologies - good for you!! :-)
From a tooling perspective it sounds like SL4 is an ideal route to follow. This is highly likely to be released in early 2010 and has some awesome new features compared to SL3. Would also recommend using VS2010 and WCF RIA Service too.
From a code sharing POV have you considered hosting your project on Codeplex? This will give you a hosted TFS server to manage your source code in a distributed way. This is bound to save you some big bucks.
As far as document management is concerned Google Docs are certainly worth a look (as is Google Sites as a really easy to set up (albeit simple) project management portal).
Finally, I can't recommend learning SketchFlow highly enough. As a prototyping tool for silverlight it is really, really cool. Take a look at the PDC video for a great kick start on this.
Good luck :-)
What are the pros/cons to using CTP technology for internal production softtware? By internal production I mean it's software we're not selling to anyone else but will be used by a large number of internal employees spread nationally.
I can see the obvious plusses (features and functionality that beats existing systems) and minuses (bugs, lack of support, changes in the interface, risk of discontinuation.) I'd like to hear from people with experience using preview tech in production software and the kinds of hurdles and things that we might not be considering.
The technology in question is the Silverlight Bing map control CTP.
Thanks,
It's a call that can be tough to make and really depends on your circumstances. A beta control from Microsoft, targeted at developers, that fills an immediate and important need, may be just the right fit if you are understanding the lack of support.
Especially given how quickly internal apps and even public sites go through revisions and quick improvement milestones.
The Silverlight Toolkit has been trying a new model for the last year; we've introduced special quality bands, to help customers make a call, and understand the investment and guarantees that the product team is making. I sort of hope we can get other teams to make a similar commitment.
The AutoCompleteBox control was essentially CTP a year ago, in the Preview quality band. Since then we invested and shipped it in the Silverlight 3 SDK as a mature, supported product.
Have a discussion with your management to define what risk you can take on while still enabling your internal users with quality value (scenarios that do work great, regardless of the released quality under the hood).
Consider source code!
One thing that you can also do is have a discussion around source and binaries. Although you won't always have an option to grab the source for many controls or frameworks, there are a lot of open source releases available today. Your control vendor may also be willing to offer a source license.
The cost for maintaining your own private branch of an open source control is high, but it is an avenue that can be explored if you need fixes earlier, want to add your own functionality, or feel that a developer day of work might just get an existing control customized for your scenario.
Updating with some more specific links:
Silverlight Toolkit
Here's more information on the Silverlight Toolkit's Quality Bands, for those that are interested. They are Experimental, Preview, Stable, and Mature; Preview is much like CTP, Preview - Beta, and Mature - Released and supported.
These are all just words, but they are "the word" of the team.
Microsoft Connect
WRT the Bing Maps control, I did see that there is a Microsoft Connect site out there. That's a great resource to have - although I am not in the program, typically Connect sites are there to help provide more frequent drops, a set of forums for discussing any issues, and a way to easily get in contact with the developers and testers on the product.
Other vendors
There are many other vendors out that that provide early releases, feel free to use the comments to add a non-Microsoft angle to this. I wanted to provide my opinion on these topics since I'm pretty familiar with a lot of the Silverlight-specific Microsoft frameworks that are out there.
Personally I don't think it's a good idea, as essentially your internal employees are your market, so this is essentially production software.
So things like licencing, compliance, support, SLA's may need to be thought through.
I know that would be frowned upon by my IT Director and Internal Audit people, to name two.
Are you reasonably sure it will work and not kill your employees' pets? Then it ought to be fine.
Seriously, just be sure it works for the target audience.
As always, IMHO.
Sometimes you just dont want to wait for a new feature, for instance we started using SQL Server 2008 in our new architecture just for the DateTimeOffset. We used this application internally, but this wasnt a major deployment. If its stable enough then why not. The Pros are you dont have to wait, you're testing new techniques, code and keeping up with technologies.
The cons are that some features will change, API arent finished or some things get renamed. These things present themselves pretty quickly and are normally easy to change. Also some things may not be documented, but there is always someone blogging about it.
With the tools available today like HockeyApp to manage betas for my apps I am less afraid to use preview APIs in beta versions of my apps. This way I can work out new functionality with real users who want to try out the bleeding edge.
When I have keep the new version limited to a small set of users this has been fine.
The times I have used preview technology in production I have been occasionally bitten by the bleeding edge. I have had to work around bugs or live with them while I waited for them to be fixed.
I've been developing with XHTML, CSS and Javascript for about 4 years now.
I love it a lot and hate it a little. I've looked into Flash and Silverlight a bit, but as a developer, I'm not too keen on them.
One reason is that they lock you into a vendor and generally, into using that vendor's tools. E.g. Adobe Flash or Microsoft Visual Studio, etc.
Also, Silverlight seems to mix content, layout/styling and behavior and into a single markup language, whereas I like the XHTML way of separating them out in code, but bringing them together in the user's web browser.
I also applaud the usability of the web, e.g. back button, hyperlinks, etc. which are set-in-stone standards that people are used to dealing with.
However, I'm seeing a lot of industry support for Silverlight and Flash. As far as .NET Developer jobs, I'm seeing less jobs for front-end/.NET developers and more jobs for Silverlight/.NET developers.
Will HTML developers still be employable in the future, or should I consider moving to a proprietary platform such as Silverlight?
While Flash/Silverlight skills may be worth developing, I think you will find that general web development skills will still be required for some years to come. Mobile apps in particular seem to place more emphasis on good, basic web design without dependence on plugins and or client-side code. Eventually, I would expect web standards to evolve to subsume the best (or at least most used) features of proprietary plugins. The web, at least, seems to be a place where people tend to favor solutions that maintain independence over lock-in to specific vendor technologies.
No, I think that idea will never fully catch on. The problem is really about the platform being developed on.
Look at how accessible the web is. Almost any machine can get on the web. My phone, my iPod, my laptop, my 11 year old PII machine, my gaming tower, all can access the same web.
The devices I have are not the limit to what can reach the web either. I think just about every gaming platform and cell phone can get on the web, as well as thin terminals running any OS imaginable. I'm sure there are others also.
The big thing looks like it's going to be the mobile market in the next few years. Some mobile devices can run flash, but it isn't used much because of the poor support & performance. The only way that the mobile web can work is by using pure standards based solutions, because that's really the only baseline that can be trusted to exist.
No matter what proprietary technologies come out, I can always rely on the fact that my XHTML pages will still render successfully on whatever device decides to access it. The same can't be said for flash or silverlight.
At the same time, I can also guarantee you that there will be a bigger market for flash and silverlight because the web is becoming more "media rich" in some niche markets (YouTube, Adobe Air, Hulu, Google Gears, etc. to name a few examples). There will absolutely be a market for it, but I wouldn't say it will defeat XHTML and web standards because the web is constantly being redefined.
No matter how much Flash or Silverlight try to take on, the technology will move so fast that the only baseline that I think will remain will be standards like XHTML and CSS.
Flash has been around for years and still hasn't taken over. I think that is one good example of how hard it is to replace XHTML.
Go for server-side development of any kind, but I wouldn't become a Silverlight or Flash specialist.
<CrystalBallMode>
To be honest I can't see it happening. Other than the reasons mentioned by tvanfosson and DanHerbert, the XHTML + CSS + JS stack just grew mature enough so that things like AJAX and jQuery make pretty much all the lightweight client side stuff easy with these tools (as opposed to things like streaming video, heavy computations or sockets etc.)
Common technological inertia will just guarantee that the existing things will stay around. People are much more likely to use something that has been around for a while and has been extended to meet the latest requirements than to use something totally new. Of course there are great paradigm shifts every now and then like the native to managed code transition but I don't see that happening with Flash or Silverlight.
</CrystalBallMode>
My hope is that what comes out of all of this is a new standardized web platform truly suited to building the web applications that people want to see with tools that developers really want to use. I see all of the effort going to trying to shoehorn these legacy web technologies into the "Web 2.0" model and I just wish that this effort could go towards making a truly revolutionary "Web v.Next".
Don't get me wrong, I really like what jQuery is doing to make Javascript client code easier, but it's still Javascript and my personal preference is to work with strongly typed languages with productive development tools.
In the meantime, I think tools like Silverlight and Flash have a lot to offer and help you do things more easily in some cases than in other web technologies, and there are some things you simply can't do any other way. But I don't think Silverlight or Flash or any other technology is the end game, just a step in the right direction.
Consider for a moment that you can manipulate a web page using Javascript, (X)HTML, and CSS with a great deal of overlap in functionality and yet ALL three technologies remain in prominent use today. The reason for this is because all three languages are different tools meant to solve different problems and no one of them can serve as an adequate replacement for the other.
Its the same thing with Flash / Silverlight vs these existing web technologies. In fact, I work in a dev shop that builds Flash based e-learning. One of our current products was originally built to use a purely Flash-based solution for navigation, etc. However, as the product has continued to evolve we have actually moved a lot of the functionality from the Flash-based e-learning module and into regular html pages.
In other words, I don't think that we'll be abandoning the current tools that web developers use any time soon. For the most part I see Flash / Silverlight as additional tools that will solve particular problems better than we were able to solve them previously.
Neither one is going to win out anytime soon. I expect which one is used will depend entirely on the purpose for many years to come.
The reason you're seeing so many job offerings for Silverlight of late is because it's a relatively new technology and just recently gained some momentum.
Though, I do expect Silverlight to make quick work of Flash.
I sure hope so. And yes, I think they will. There will be some development on legacy (XHTML/CSS/JS) apps for re-tuning purposes, but I think there will come a day when new apps are simply not created on those platforms.
Mobile phones are the issue right now. Flash isn't available on many of the major phone models. And their browsers are all over the map. Luckily there's Webkit (iPhone and G1).
If Silverlight makes it to a web platform then it will be a nice viable alternative to the hodgepodge of technologies that are currently in use. FYI, Microsfoft says Silverlight on Android is very possible. On the iPhone, hard to say, Apple is weird about such things.
AOL recently created a RIA version of it's email client in Silverlight. Looks nice and there's no Javascript errors to worry about. From a developer standpoint, that's huge.
