i am working as reports developer using Cognos BI and i want to learn any one of below BI tools.
Microstrategy
WebFocus
Can any one suggest the best tool from above to learn in career perspective.
Thanks,
Phani
Disclaimer, I'm a former MicroStrategy employee and I never worked on WebFocus.
My suggestion is to go with MicroStrategy, first of all your knowledge of BI and SQL will came very handy to you to understand how the MicroStrategy SQL engine works and how the objects you create in MicroStrategy will be transformed on the database side.
So, if you have your back(-end) covered you can focus on the other key features of MicroStrategy: in memory cubes, possibility to connect to MDX sources or webservices, advanced analytics and above all the mobile part.
If you are more interested in the nerdy stuff (maybe it's not your case, but I came to BI from the SQL side) the focus on the Mobile and Data Visualization (MicroStrategy Visual Insight) can be a bit appalling, but I believe that to have an exposure to the front-end components is important to see the big picture.
Anyway career wise MicroStrategy looks to me a more wise choice than WebFocus, but as I said at beginnin my perception can be biased
Offcourse Microstrategy.
Its an awesome tool provides the vast ability to analyze huge amounts of data.
Microstrategy provides flexibility to the users, good scalability, nice user interface & impressive iPad capabilities.
And career is always green compared to WebFocous.
My vote goes for Microstrategy!
Thanks
I've always tried to make decisions like this, by focusing on what will be best for my users, rather than what would be best for me.
To support this type of focus with the question at hand, take a look at things like strength/longevity of vendor, scope of product offerings, simplicity of implementation/maintenance, number of back-end databases/appliances supported, number of/type of report/graph formats, scalability,...
Good luck with your decision!

Recently I learned Tableau Visualization tool but I am not able differentiate between Tableau and QlikView.
could any one detailed me what's functional difference, I take round in google so please don't reply copy past from google.
Not a detailed functional difference analysis, no, but an overview as I see it.
Tableau is, as you say, a visualisation tool - it has some fairly simple data loading capabilities, but for complex environments relies on other data extraction tools like Alteryx. Tableau focuses on the front-end with things like a wide range of chart types, recommended chart types based on the nature of the data. That said, it is not a fully-responsive web-based product - you design separately for mobile and other different screen resolutions.
QlikView it's fair to say isn't as "pretty" as Tableau, but it does have a very powerful data extraction script language as well as in-memory associative technology for very fast data analysis. It's also not fully-responsive in a web browser - although it does have some limited mobile functionality that works out of the box.
You should also look at Qlik Sense (essentially the successor to QlikView) which seems to me to be the best of both worlds - it's visually appealing like Tableau but has the powerful ETL tools and in-memory technology of QlikView.
Hope that helps. I think the Gartner BI 2017 report just came out, so it'd be worth looking at that for a broader overview of capabilities across BI tools.

I have been evaluating DNN over a few months. It has it´s pros and cons. I find it hard to evaluate systems by reading articles and don´t have time to check them all on my own.
What are your general feeling about this?
As my background is with .net, which system would you choose?
Also, does anybody know if these pages at stack overflow is based on a CMS and if so which?
Since everyone would rather spend more time criticizing your post than answering it, I'll give it a shot.
You have a few options with building a portal. Either go with an established, open source portal (like DNN), look into some paid solutions or build your own.
Open Source - I've worked with DNN and MojoPortal. DNN is a little slower and has a few more requirements to develop skins and modules, but it has A LOT more features and some of the free/paid modules are really cool. Overall, DNN wins here, but if you don't need a large portal and you want to keep development really simple, MojoPortal might be better. MojoPortal has a few nice features that makes it easier to configure.
Open Source (Other) - There are tons of them out there. Orchard is one I'm thinking of because I'm interested in MVC. But, it's still young in terms of features and support.
Umbraco - I can't really speak to this because I have not used it, but it does have some popularity.
Build it - This is an option and allows the most flexibility, but it takes a lot of time and so many features that are built into these portals could be left out. Role based access, page management, page/module permissions, downloadable modules, profile/profile properties, file management, skinning, acct management, menu management, event logs, etc
I left out non .NET solutions like ones based on PHP, Grails, etc because you are a .NET developer. There is plenty out there, but sticking to .NET will help speed your development up.... unless you are just wanting to learn something new.
Hope this helps.

I am looking for some tool or service that can be used to track arbitrary events in web based software, for the purpose of running A/B tests and measuring various other things. I am aware of Optimizely, but that seems only suitable for testing simple things in normal websites and Google Analytics is not really suitable for this type of things and there is a lot of hassle when you want to track events from the backend and link them with a user's session in GA.
An ideal solution would be some service accepting HTTP GET requests with arbitrary parameters and then letting users do queries in an SQL-like language. I have many times put together some less scalable solution with MySQL or a less flexible one that stores everything in text files and processed and aggregated them separately into desired format. But building a both flexible and scalable version would require a lot more time and I guess there are already good solutions out there. Does anyone know of any?
Other requirements are:
It must be possible to do both back-end and front-end requests.
It must be possible to do use it in widgets, running on other peoples' websites
It would be nice if it could automatically create readable reports with maybe some diagrams, etc.
If anyone has any experience with this kind of tools, I would be very glad to hear your thoughts.
Thanks for your help.
Have you tried mixpanel? We've found it quite flexible and powerful.

I'm looking for a good tool (or library or a framework) that I could use to easily build basic content management functionalities over MongoDB.
I am very well aware of the Admin UIs listed in Mongo's website, and I'm already using RockMongo for query and some db admin tasks. The problem is that while I as a software developer can happily use these tools, they are too powerful and complex for the people who are responsible for managing the content in the database.
So I'm specifically looking for a MongoDB content-management tool with:
Ability to easily build (scaffold) user interface around collections (generated create, read, update and delete forms / views)
Ability to add data validation and some template or schema for objects, especially when new objects are created and added into a collection
Support for fine-grained access control (user groups, per collection and per object read/write/admin access)
I've been considering using django-nonrel for building one, but would like to get more opinions before going any further.
Since you're looking for a solution beyond a straight Admin UI, I expect you will have to roll your own. I went through a similar exercise a few months ago and ended up using Yii Framework (PHP).
The attributes you're looking for (scaffolding, validation, RBAC, ..) are common to many frameworks. Are there specific languages you would prefer/consider using? There are frameworks/libraries for Ruby, PHP, Python, etc. Many of these go to lengths to coerce MongoDB into an ActiveRecord/ORM pattern to enable use of CRUD and scaffolding. An emerging approach for working with NoSQL data sources is the DataMapper/ODM pattern, which is a much more comfortable fit compared to ORM.
Have a look at penguin: a module that automatically generates administration pages based on your Mongoose models.

My shop is trying to formalize the release management process for an OSS product we maintain (edit: using SVN for version control). It's a sort of a web development framework/CMS kind of thing, as in it's a product that other projects are built on top of. This makes clear communication about the versioning system especially critical for developers that are using the tool.
I'm hoping to find some examples of how best to graph this system so we can communicate it better internally and with outside developers. I know there are lots of standards and best practices around versioning, so I'm hoping this extends to some sort of visual vocabulary as well. As one example, there is a nifty graph at http://en.wikipedia.org/wiki/Versioning#Software_Versioning_schemes. Are there any guides out there on how these sorts of things should be designed?
First, if it is an OSS project, chances are the versioning system ism a Distributed one (DVCS)
If so, then this branching model can be of interest.
The idea is to control what you want to integrate from remote repos.

I need this too. The built-in graph in Tortoise SVN is too busy, but I've made use of it. But for soemthing like VonC's picture above, I think I'm going to go with a dry erase board and colored markers. I'll hang it outside my cube. Annotate it with revs, dates, sprints and projects, and we'll be all set.
