Qlik Sense

Avantages

Qlik Sense est un outil assez simple à apprivoiser lorsqu'on maîtrise déjà l'exploitation de données. Il est assez aisé de construire des rapports et tableaux de bord. Le plus : le filtrage qui rend une visualisation immédiate des analyses effectuées.

Inconvénients

Mériterait d'être encore plus intuitif qu'il ne l'est. Et forcément le coût du logiciel qui reste encore élevé.

Avantages

Qlik Sense est une plateforme BI, qui permet d'analyser de manière fluide vos données

Inconvénients

Personnalisation limitée, demande également d'avoir des compétences en analyse de données avant de l'utiliser

Avantages

C'est un outil qui peut permettre d'avoir une quantité d'informations en un rien de temps avec des filtres à tout moment, qui remettent à jour l'ensemble des feuilles, tableaux/graphiques en fonction du filtre demandé. L'interface est simple et efficace.
Je recommande ce produit.

Inconvénients

Le coût peut-être, sinon peut-être le degré de connaissance assez élevé qu'il faut posséder car, en fonction des configurations faites, de fausses données peuvent être difficiles à repérer et peuvent donc passer inaperçues.

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

- Responsive and intuitive Interface- Ability to drill down to the data line level- Ability to export the Dashboards to various formats- Ability to use the Dashboards in presentations- Integration and Data Import capabilities

Inconvénients

- Pricing structure- Automatic distribution of reports requires another licence- Somewhat steep learning curve- Can require high processing power for complex dashboards

Avantages

Qlik Sense can be installed both on prem and on cloud, which give the organization using it the ability to have better control of where the data will be stored and accessed from, which is a great benefit when you want to keep your data safe and local.
Another great thing about qlik Sense is that with a bit of time one can create very clear and good dashboards presenting the business data in the organization.

Inconvénients

Qlick Sense is quite expensive compared to other tools existing in the field such as Tableau, in addition, it's not an easy tool to onboard and it can be costly when dealing with big teams using the tool.

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

Associate data model and insights advisor

Inconvénients

Issues while learning new things and advanced concepts

Avantages

Being able to connect to very diverse data sources, the ease of creating new dashboards and reports.

Inconvénients

The only con I can identify is that we don't have enough time to keep up with all the features that Qlik Sense brings, and further develop the data analysis capabilities. But in time we will manage :)

Pourquoi passer à Qlik Sense

Avantages

The collection of interactive dashboards, graphs, and charts detailed in Qlik Sense makes it easy to demonstrate otherwise complex data in a straightforward manner. The platform offers a distinctive approach to associative data exploration, which equips the users with the ability to ask further questions and go deeper into their data.

Inconvénients

Adding capabilities such as making full custom visualizations or integrating outside libraries could be enhanced to fulfill specific storytelling requirements.

Avantages

I like its advanced data exploration capabilities whereby we can easily extract the data that we need through the smart search function.

Inconvénients

Working with complex data visualisations can affect the overall performance but we have noticed improvements on this.

Avantages

The visuals are great and are very supporting towards good storytelling dashboards. The ease of use is also good as compared to other available reporting and visualization tools.

Inconvénients

I personally feel that more data connectors should be introduced to make it more competent with other visualization tools

Avantages

Qlik Sense is a powerful tool that allows you to monitor the evolution of your management indicators, it has interactive graphs that allow the user to analyze the data intuitively. In addition, it allows you to extract analysis of the indicators in real time and facilitates the implementation of strategies or collaborate in decision making.

Inconvénients

The cost of the license is a factor to consider, and the degree of difficulty will depend on the user's experience, even for new users the learning curve can be quite steep.

Avantages

I like that it supports the drag-and-drop functionality besides it being able to handle large volumes of data and perform complex calculations.

Inconvénients

It can be expensive to license and maintain, so if you want to use it, use it fully.

Avantages

Qlik Sense enables powerful filtering and capabilities to model comparisons. It is user friendly, helps to generate central reporting solution with governed security rules.

Inconvénients

Syntax of expression is different from other languages makes it inconvenience. In case of large data, loading speed of app may be slow.

Avantages

It is very visual and easy to use, lot of graphics are available and easy to learn.

Inconvénients

Sometimes it is difficult to change some features and this can cause confusion.

Avantages

Reporting and analysis features.Easy to use.Good UI

Inconvénients

Working with multiple data sources is difficult in qlik.Increases the server load for large datasets.

Avantages

First its usability and design. Regarding the User Interface: the application is well designed and I felt like every button and function was where I would expect it to be. The program is responsive and fluid, you always know where you are and what you should do. Having said that, there is some learning curve to the many features, which are a good thing. The program is easy enough to create a histogram with a simple spreadsheet while also allowing for much more complicated statistics and good looking charts, e.g. plotting geo-data, heat-maps, box-plots and so on.
I specially like the ability to write your own aggregation functions and even more the dashboard where you can put different charts and statstics and build an interactive and dynamic kind of storyboard. The interaction works seamless. If you select (in a bar chart) a specific bar or group of bars, the other charts will automatically adjust to show just the relevant/selected data. The program does not hesitate and performs really well, even with large quantities of data. Support is also pretty solid and there is a lot of information and questions already answered on the online forums. It supports many of the standard data sources.

Inconvénients

The aforementioned ability to write your own functions has a somewhat steep learning curve. You do have to search online for the primary functions you need (though these are well documented). Unfortunately if your data has to much variables or data points, the charts prioritize the specific variable instead of the whole diagram. What I mean by that is that you can end up with a very large horizontal chart in which you have to scroll horizontally to find the other data instead of 'cramming' all variables into the visible space. This depends on taste, but I did not find any way to change that, which brings me to the next point. The charts are somewhat 'customizable' regarding color and design. However, I've used comparable software which allows for much more flexibility in the structure and formatting of charts. A few times it can get frustrating to use the program, mainly for two reasons. 1. The aforementioned displaying of information in a non-customizable way and 2. the lack of knowledge of how the program really works that hinders you from doing exactly what you want. But of these aspects become less of a problem, the more you use the program.

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

Qlik Sense is a lot easier to pick up and get going with than QlikView, but has most of the same underlying capabilities and benefits. It is also more of a self-service tool for business analysts as there's less technical skill required to build charts/graphs in Qlik Sense.

Inconvénients

Qlik Sense is great, but to get the real power from it, you still need to learn Qlik's scripting language. It doesn't have quite the same level of functionality that QlikView has, but is catching up quickly. If you're dealing with large volumes of data, the hardware requirements can be quite large.

Avantages

it is continuously updated with interesting new features, it's user friendly, it is a program that takes into consideration the design and the new trends, it is nice to see and the animations on the graphics make it even more innovative

Inconvénients

tokens are too expensive for a medium-sized company, the QMC is still a bit complicated to use. Updating qlik sense server is a bit tricky, (especially moving from Synchronized Persistence to Shared Persistence)

Avantages

Qlik Sense is sensational software to deploy confusing data models. When you have lots of data sources and you have to integrate into one data model and get the result. I love the analytics sections in Qlik Sense; it is super interesting and easy to conclude by viewing its analytics. The best thing is that I can easily install it and accumulate my data into it.

Inconvénients

You need to have some technical knowledge about Qlik Sense so you need some training to understand it. I struggle a lot with customization. It is difficult for me to customize as per my convenience. The current themes are very dull. I don't like them. The charts are arranged automatically which little setting options to configure them. According to me, Qlik Sense is expensive software.

Avantages

-It's Simple for new users and allows self discovery.
-It very fast and code is easy to learn.
-There is a lot of material to learn and a good community.
-Allows you to build your own datawarehouse using Qvds.

Inconvénients

-You need to pay extra for features like Automated Report Generation (NPrinting) and also if you use SAP you need to pay for a special connector.
-You rely on external extension to build nice dashboards but they are improving in this area every month.
-It's expensive compared with others solutions.
