I have been researching OLAP servers such as Tableau, Jasper, BIRT iHub, etc.
but it appears that none of them provide reasonable support to customise the
user interface. All of them use the browser as the rendering system but
changing their default screens or "viewer" windows is not encouraged
(possible?).
I DO NOT want to write a full fledged J2EE application and drop JAR files
in the WAR. I have done it in the past and was expecting improved support
for this type of requirements.
Any pointers?
Thanks for the additional info.
May be the Swiss tool, icCube, can help you. icCube ships with an in-memory OLAP engine and built in web reporting application. You can embed the software seamless in other web applications, so adjusting the look-and-feel and customer branding is relatively simple.
As the reseller of icCube in The Netherlands, I have implemented icCube at several clients that were looking for an affordable dashboard solution that could completely blend into their product. Based on our customers' enthusiasm I think I can say we succeeded in that.
You can view some live demo's on our website. Also tons of info is available at icCube´s site. If you want more, I can show you some embedded examples through skype if you want to.
Hope this has helped.

I'm currently in an internship and i have to create a whole BI application.
I think i'll use pentaho, and I have to use just open source component.
I know that Pentaho Analyzer is not free
My question is: Is saiku an equivalent of analyzer?
If yes, can I use it with pentaho instead of analyzer?
thks
I'm the developer of Pivot4J project and want to share my (subjective) opinion on the subject.
First, as though you righteously assumed Pivot4J to be more of an API than an application, it does not always mean you need to write lot of code to use it.
We also have a Pentaho BI plugin which does not require any coding and has comparable features to Saiku plugin, though it's targeted toward the yet unreleased Pentaho 5.0 platform.
And our sample application provides most of the functionalities that JPivot web application has, even though it lacks a data source configuration feature which will be soon to be fixed.
Compared to Saiku, I think each project has its own advantage in different scenarios.
Saiku has a much lightweight architecture on the client side than our sample application and the plugin, so it can be deployed and embedded virtually anywhere.
While it's not much difficult to create a full REST style analytic application with Pivot4J, our current sample and plugin applications require at least a Servlet container to run and are more difficult to be embeded than Saiku in certain environment.
On the other hand, as Pivot4J is designed to be UI independent API from the start, it could provide more flexibility than Saiku in my opinion to developers when they want to build their own application on top of it, or intend to customize core behaviors of the API.
For example, if you want to use Pivot4J with your own application which is build with ExtJS, DhtmlX, or any other UI toolkits, it'd be much easier to achieve a seamless integration with Pivot4J, as it provides you with convenient abstract extension points to do that.
Finally, if you're familiar with Javascript you might find working with Saiku easier as it delegates most of the UI related works to the client side.
On the other hand, if you're an old school Java developer like me :) you might find our sample application to be easier to understand and work with, as there's virtually no custom script involved and everything is done on the server side with JSF component model.
To conclude, I'd like to say that Pivot4J is not just an API which cannot be used without writing much codes as it already includes quite feature complete Pentaho BI plugin for the upcoming 5.0 release of the platform. And as Pivot4J and Saiku take rather different approach from each other, each has its own strength and advantage which could be leveraged to suit the specific use case.
Yes of course. Both the tools use the same underlying OLAP engine - Mondrian. Saiku is essentially the same as analyzer providing many of the same features - however it has a different architecture which additionally makes it very embeddable and pluggable. Plus Saiku can be used standalone too if you want to.
Check out the demo at dev.analytical-labs.com to see what it can do.
Also for help you wont find many tools with such a great community - hook up with them on Freenode IRC at either ##Pentaho or ##Saiku depending on your questions!
Pentaho is the right choice for OS BI too - Presume you looked at Jaspersoft as well? Worth a look but you'll no doubt realise the features are better in Pentaho.
Have you think about a pure javascript UI to pivot your olap cubes? There is one such component calls WebPivotTable at http://webpivottable.com
Jpivot, saiku and pentaho are all based on olap4j API so that they all need a java server side service. WebPivotTable use AJAX call to xmla service directly so that it can be used to pivot any xmla OLAP server, like mondrian, SSAS, iccube. Since it doesn't tie up with any java back end and also it is pure javascript based, you can easily integrate it into any website or web application.
What's your experience in using web technologies (HTML, XML, CSS, JavaScript) to implement part of the functionality of a GUI application? Pros and cons, please.
No servers, relational databases, AJAX, or cookies for session management, nor an existing webapp either, but rather a GUI app that uses web widgets (like Qt WebKit) to render and handle substantial parts of the UI, while taking advantage of a GUI framework to achieve an even richer interaction and better desktop integration.
I've already validated that the approach is possible using PyQt. Content can be rendered from the file system or from strings, and URL requests (images or clicks) can be captured and served by the form's event handlers. CSS and JavaScript are supported, perhaps with some limitations.
# ...
self.webView.page().setLinkDelegationPolicy(
QtWebKit.QWebPage.DelegateExternalLinks
)
#...
class TotiMainWindow(QtGui.QMainWindow):
def linkClicked(self, url):
pass # events arrive here
Note: This question is different from this one and this one made before, among other things because there is no requirement to use web technologies on the GUI, but there is the requirement that the application should work without a network connection available, and should integrate well with the default desktop over different platforms, without previous infrastructure requirements (no .NET, Java, browsers, or database servers).
Note: I posted a different version of this question on PMS but found very little experience with this approach there.
Closing Note
I just found most of the information I was looking for in a series of blog posts by André Pareis.
I think the largest advantage to using web markup like HTML/CSS and other web technologies is that desktop apps may very well have their days numbered.
As we speak, Google engineers are working on the Chromium OS, which essentially consists of a single GUI application... the browser...
Now, while nothing may never actually come of it, there is clearly a rising trend in the number of applications accessible through a web browser, accessible anywhere. It seems to me that this is the future of application development.
By using these technologies, this becomes one less headache you have to deal with when or if you determine that your app should be available as a web application.
Update: A few years ago, we developed an Agent Desktop for our call center that is essentially a local application that opens sockets to integrate with the phone system. The user interface the agents use is built with HTML, CSS, and JavaScript, and the experience is stunning. When we released our latest update in 2010 with a professional CSS redesign, our agents were all very impressed with not only how easy it was to interact but also how easy it was to use.
In the future we will port this 100% to the browser, but for now it needs to be a local application because of the COM integration with the phone system.
We did exactly this for a project back when Windows XP was new.
This gave my team several benefits:
A good-looking UI with relatively little effort
Easily change the style of the UI in a consistent manner using CSS
Relatively simple integration with C++ (invoking functions from the ui and vice versa)
The drawbacks we saw were:
Some not-so-good firewalls considered accessing internal resources (ie other html pages in the ui) to be a web request
Adding and accessing the needed resources could in some cases be a bit cumbersome
It was possible set properties in Internet Explorer that would prevent JS from running in the application
Note that some of Windows XP:s programs are using this approach.
This probably works best with small, more Wizard-like parts of the ui (which our ui consisted almost entirely of).
I have since then not really been involved in ui projects, so I cannot really tell you whether this approach is still valid... I know that MFC-based applications will let you use HTML-based dialogs though.
In a similar situation in 2005 I created a stand-alone webapp using XForms, CSS, JavaScript, XML and XML Schema for offline data retrieval and verification. With a good XForms -> HTML + JS transformer (Chiba) it did the job with no bug fixes after the initial release. It was used for 6-12 months (IIRC) by about a dozen engineers for a project gathering test data in the tunnel of the Large Hadron Collider. The biggest surprise of that project was just how much you get for free when going for a web platform, even for offline use. Highly recommended.
The major problem is that it reduces your development speed, or the quality of your user interface. A lot. Unless you're using Seaside, it is much faster to develop a desktop app.
There is quite some number of applications built on top of Mozilla platform. It isn't 100% web technology, as instead of HTML you use XML based XUL, but the rest is indeed web stack (JavaScript, CSS). The most successful of these it the OpenKomodo and it's commercial big brother Komodo IDE.
On the other hand, as far as Qt goes, the newest version 4.7 you can build GUI using QML language. Don't let the name mislead you, it's not markup, it acctually JavaScript with app-specific extensions.
The question says it all, we know most of the hosted web-based UI prototyping tools out there, but we would like to have ours hosted on our own internal servers, preferably with on-line multi-user collaboration functionality (i.e. users modifying the prototype, making comments, etc. in parallel).
Any suggestions will be appreciated.
Sketchflow (in the top-end version of Expression Blend from Microsoft) meets almost all your criteria. It ain't cheap, but it is very powerful.
The deployment package of a Sketchflow build can just be placed on an internal server (no IIS required to deploy).
Multiple users can overlay their comments and pen drawings over the top of the screens. Their feedback is packaged as a unit and sent back. All feedback can then be loaded back into the Expression Blend project and the feedback from 1 or more users viewed overlaid on the correct screens.
It does not meet your multiple-user authoring requirement though, but as they say "too many cooks...".
Most tools are either desktop based or hosted. Seen very few which offer a downloadble multi user version. iRise is one choice with the editor as a desktop product and a centralized server for sharing among users. The budget is typically from $50K to $250K. A similar option exists for Serena composer as well, not sure of the price though.
Both iRise and Serena are not real collaborative tools, the central server is only for sharing the finished prototypes and getting feedback.
If the requirement is for a completely web based multi user tool then 10screens can be an option - http://www.10screens.com. The same product available on the site in a hosted mode can be downloaded and installed on your own servers.
I'm a junior VB.net developer with little application design knowledge. I've been reading a lot of material online regarding different design patterns, frameworks, and methodologies. It's become a bit confusing for me.
Right now I'm trying to decide on what language would be best suited to convert an existing VB6 application (with SQL server backend.) I need to update the UI and add more user functionality and reporting capabilities. Initially I was thinking of using WPF and attempting the MVVM model for this big project. Reports would be generated from SSRS.
A peer suggested using ASP.net and I don't have enough experience to determine what would be better. The senior programmers here are stuck on using VB6 and don't have any input on what to use. They are encouraging me to use the latest technologies.
This application would be for ~20 users in a central location. Ideally I would stick to a Microsoft .net language. Current interface is similar to a datagrid table where the user would click in to see the detail of each record. They would need to have multiple records open at any given time.
I look forward to all the advice I can get.
EDIT 2010/04/22 2:47 PM EST
What is your audience? Internal clients within an intranet
How complex are the interactions you expect to implement? not very... displaying data from SQL server to UI. Allow user updates to said data. Typically just one user modifying a record.
Do you require near real-time data updates? no
How often do you expect to update the application after the first release? twice/year
Do you expect a well-defined set of client platforms? Yes, windows xp environment, potentially upgrading to Win7. Currently in IE.6 moving to IE7 or 8 within a couple of months.
Do users need access from anywhere? No, just from their PC.
What would be wrong about building a simple ASP.Net application in VB.Net using Gridviews for allowing the data access and manipulation? Seems like a simple ADO.Net trial application if you aren't familiar with it in the beginning you will be by the end. CRUD applications are pretty common so it shouldn't be too hard to build it and then refine it as more requirements become apparent.
Sounds like you need to use a web-based solution--this eliminates alot of your potential distribution woes with multiple users. You could use silverlight, but if you are locked into SSRS, this might not be the way to go.
Just wondering what software you use to create a visual sitemap / site structure representation before you start big sites?
I am looking to map out a large site, but cannot find any good software to help me map the site visually (And in pages/categories)..
Maybe SketchFlow http://electricbeach.org/?p=145 ? which is included in the Expression Blend Trial http://www.microsoft.com/downloads/details.aspx?FamilyID=92E1DB7A-5D36-449B-8C6B-D25F078F3609&displaylang=en
I strongly suggest taking a look at this tool: http://www.balsamiq.com/products/mockups
The Balsamiq tool is the best for doing mockups (i assume this is what you are referring too when talking about sitemaps before you start...). With this software you can quickly generate a working wireframe of what ever you are creating. So much functionality that you can actually share it with your client to get some good sign offs prior to typing the first bit of code.
Very powerful!
And the other one...just shown at the last MIX09 is SketchFlow. Couldn't remember it to save my life. This is a WAY COOL tool for site maps and UI mock up. I was trying to find you the actual MIX presentation as it is super cool to watch. But here are some YouTube videos of that presentation from a user perspective I guess.

I know this is an old question, but for others who find this via search, I personally love mocking my websites up with mind mapping tools. I've tried several but my favorite was MindNode for Mac and Xmind for Windows.
XMind free download:
http://www.xmind.net/
MindNode free download:
https://mindnode.com/
I've also tried MindMeister which works just as well as other mind mapping tools and is hosted for you so you can access your mind maps anywhere. However, MindMeister only allows you three maps (currently) without upgrading to a paid subscription.
Another that I've worked with is mockflow.com which is great for mocking up websites with all their features and buttons and even making clickable navigation. They have a free version, but again it's very limited without upgrading to a paid version.
I'm using Slickplan. This cloud based app allows me to have access to my projects from different machines regardless of their operating systems. All I need is one of the leading web browsers (Chrome, Firefox, Safari).
With Slickplan you can create visual sitemaps from scratch or you can use Site Crawler to import your existing website to visualize and reorganize its structure.
Of course you can always export your projects to the XML format, and use the exported file to create pages and menu systems inside some popular content management system - Slickplan provides plugins for WordPress, Joomla, concrete5 and a few more.
