Qlik Sense

Avantages

L'accès au script ou au gestionnaire simplifié de données et une interface simplifié pour les utilisateurs finaux.

Inconvénients

Outil très (trop?) orienté utilisateurs, peut créer de la frustration quand on veut un rapport très précis. En revanche l'outil est en constante évolution.

Avantages

Among many good features, Qlik Sense has a very good data load interface. The scripts are very easy to learn and also very powerful. You can transform and validate data at load step without have to know any programming language neither SQL, of course, if you know SQL you can make even more complex and complete scripts. The built-in and graphical data load tool is enough in many scenarios, you can even use it to generate the "gross" script and then refine it with your own rules.
Another good point is the customer support and knowledge sharing which exists in their forums, you can find almost anything you ever need there. I never needed to open a customer ticket for technical reason, but some questions regarding licensing and product availability has been quickly and completely answered by e-mail.

Inconvénients

Some minor features which is already available in other BI tools, even on Qlik View, is not available in Qlik Sense. As an example, I miss some kind of "share expression/measure" function in this tool. When we create a measure, we cannot use this as a source to another measure, or to an expression, instead, we must replicate that logic any and everywhere it is required.

Avantages

More visualization options would be great, like divisions between graphs or tables, predefined layouts to fit tables and graphs that are visually nice would be a big game-changer.
Qlik desktop is very difficult to find how to use it, I rather use Qlik sense online since I haven't been able to use it on my personal computer, in my job computer is ok and easy but not in the personal one, with a non company email.

Inconvénients

Qlik view is a powerful tool that helps share the dashboards easier and people don't need to install any program or app. The online Qlik Sense app is very useful since you don't have to install a desktop program and can be used on any computer. Is easy to use and if you know how to use Excel, you can figure out how to use Qlik by yourself or with a 30 min tutorial.

Avantages

Qlik Sense is a self-service analytical tool based on the same in-memory technology as QlikView. It's associative engine allows for snappy selections, filtering and prompt re-calculation of all charts and aggregations on the fly as the user navigates throughout the dashboard, even on datasets of over 100 million rows.
Qlik Sense focuses more on the self-service aspects of BI, where users are encouraged to build their own Adhoc visualisations without the use of keyboards simply by drag & dropping various elements, making the technology utmost business friendly. Also, as the whole technology is fully web-based, it embeds the latest visualisation libraries (D3, Raphael etc.) and allows for a seamless integration of customised extended JS charts (so-called extensions). The latter enables for unlimited possibilities when it comes to visualisations (http://d3js.org/) and further integration with web-services (R servers, real-time analytics, Hadoop etc.). Also, the Qlik Sense Server deployment is tailored to facilitate a multi-node deployment, allowing for a very scalable enterprise solution, even cloud-based.
The data security technology (Section Access) is the same one as in QlikView and is customisable, secure and robust.

All in all, when it comes to deploying a scalable and business-friendly BI solution, which has very presentable dashboards, a fast and robust aggregation engine with extended self-service capabilities, Qlik Sense is currently the best product of its kind on the market.

Inconvénients

Qlik Sense is still a new product and not very mature yet, as it has only been released a year and a half ago. The review is based on Qlik Sens version 2.1 which is important to emphasise, because QlikTech is constantly updating the software and publishing releases with enhancements and bugfixes.
Qlik Sense is not the right tool, if you requirement is:
1. To have a guided analytics dashboard, where the user is constraint in the way he views his data.
-> This can be overcome by creating mashup websites, however you will need a web developer to do this.
2. Standardised reporting via Qlik Sense and production of pdf files is not possible (yet).
-> An integration with nPrinting, QlikTech's latest acquisition, could change this and it's on Qlik's roadmap for the next year.
3. Your BI solution needs to accommodate flexible data extraction capabilities (e.g. to Excel).

General current disadvantages:
1. The story telling functionality is not mature yet - users have more benefit using PowerPoint directly. In my opinion it's missing a live connection of the snapshots used in the story to the underlying chart objects.
2. Security settings (NOT on data level) are governed centrally via the management console and are complicated to comprehend.
3. No guided analytics aspects, even navigation between sheets can't be controlled.
4. No supported data extraction capabilities. It's almost impossible to get comprehensive extract of it's underlying data, something that was possible with QlikView (Export functionality e.g.)
5. The vendor has little practical knowledge on how Qlik Sense is deployed enterprise wide within a business and is not really able to support.
6. The vendor is focusing more on the data story telling and collaboration aspects of the Qlik technologies and almost imposes those on the business. Personally, I would prefer if QlikTech listened to its customers a little bit more.

Avantages

It is a very powerful data visualization and analysis platform. It is known for its intuitive user interface and powerful data modeling capabilities. It allows us to easily create interactive dashboards and reports, and explore and analyze data from multiple sources.

Inconvénients

I have not encountered anything wrong with qlik sense.works very well
