Tableau and Qlikview are two important BI tools available in the market for analyzing data. This article is a window to a complete overview of each of the tool, along with the basic differences based on three main categories of Business, Technology, and Visualization. Every organization wants the best BI tools, to handle the humongous data that they deal with each day. Tableau and Qlikview are the two giant BI tools that operate in the market successfully on Big Data.
Understanding and analyzing each tool and learning their differences on the three important pillars of data analysis (Business, Technology, and Visualization), will help you decide on the tool to bank on.
Tableau is one of the most popular Business Intelligence tools, which helps in analyzing the data visually. It allows us to create and distribute the interactive dashboard, which displays the trends, variations, and density of the data in the form of the charts and graphs. It can easily acquire data from files, relational and big data sources, and processes it. It also provides for data blending and real-time collaboration.
It holds high importance for the businesses, academic researchers, and many government organizations, whose main focus is data collection and its analysis through visual analytics.
Tableau is regarded as a leading Business Intelligence and Analytics Platform in Gartner Magic Quadrant.
Let us understand the advantages and disadvantages of using Tableau in Business Intelligence for Data Analytics.
The remarkable visual capabilities of Tableau are what it is known for. Tableau is developed to read and handle complex data formats and computations to produce required data blending and dashboarding to present you with extremely insightful data visualizations in the form of understandable graphs and charts. The researchers say that visuals are more impactful on memory than numbers and words. Consequently, Tableau seems to have made analyzing data easier, which otherwise would very confusing through the traditional spreadsheets.
Tableau software offers the easy, "drag and drop" way of creating data visuals. Even a beginner can get hands-on the software in very less time. The interface is built to handle endless variations with an additional capability of warning you for visuals against the best practices.
The Tableau performance is great with large chunks of data. While the software is processing the big data, dashboard manages to handle the load and there will be no performance drop seen with any of the user tools. This high performance with data visualization makes it one of the popular tools with a considerably large market.
As a BI tool, Tableau is built with support for many common data sources used in the industry. Tableau can establish and manage the connections with HADOOP, SAP, and DB Technologies, increasing the radius of capabilities of the software tool as a whole. This improves the application performance of the software, enabling it to handle all sorts of data storages.
As a developer or a data scientist, it is not the best practice to completely rely on a tool for every process associated with data analytics. Sometimes, we feel the need to write our own scripts to perform some specific tasks on the data. Tableau, thus, supports Python and R. You can write scripts and run it on Tableau. Sometimes, this will perform the initial data cleansing task, hence reducing the load on Tableau. However, Python is not the natively supported language on Tableau.
Tableau is responsive for devices. The reports and other UI automatically gets resized according to the device size, it is opened on. Hence it is mobile, tablet, and laptop friendly in nature.
There are many Tableau enthusiasts, who are constantly contributing to the Tableau community growth. There are immense forums that support any Tableau beginner with the blockers he or she is facing. Overall, their community support is commendable.
Tableau doesn't offer for automatic refresh of the reports with the process of scheduling. There is no option to directly schedule in Tableau. Hence, always, there is a need for manual intervention when users have to update data in the back end.
Unlike other BI tools available in the market like PowerBI, where the visuals can be imported, Tableau lacks this feature. Whatever the custom visuals are needed, they have to be recreated within Tableau UI manually, which sometimes becomes a double work and time-consuming.
The custom formatting and limited 16 columns scaling are difficult points for Tableau users. Also, there is no way to implement the formatting directly to multiple fields. This forces the user to apply the formatting manually, which is very time-consuming.
The Tableau's parameters are static and single-valued. Hence for any change in the data encountered, the users have to manually update the parameters. There is no way the parameters can be updated automatically.
The scaling for larger organizations becomes an important limitation as the pricing of Tableau is very high for an average company. The smaller enterprises find it difficult to buy and install the product because of its expensive investment, compared to other available BI tools in the market.
The tool though is quite easy to begin with, it is really difficult to understand and utilize all the facilities offered by the tools embedded in. One needs to undergo an intensive staff training to start to meddle with the tool, in both cases of a developer and a user. This is not only time consuming, but also increases the cost of ownership.
Though the Tableau claims that it is easy to integrate Tableau into your company's environment, it is practically not so easy. It is difficult to make the Tableau integrate with the existing infrastructure to get seamless business landscape, both technically and financially.
QlikView is one of the leading Business Discover platforms available. It is built with a number of features which differentiate it from tradition BI tools in the market. It is programmed to analyze data through different colours, which are used to indicate the relationship between different types of data. It also indicates the data that are not related.
QlikView applications manage data automatically, without any manual intervention. Its best features include, the in-memory data processing and data compression to 10% of the original size. These advantages make it the best in the field.
There are both advantages and disadvantages to Qlikview as a tool for BI. Let us understand each, in detail.
Qlikview provides a dynamic BI user interface, where, with a single click, one can consolidate, visualize, and analyze data sources to unprecedented precision.
The visually advanced and dynamic dashboard allows for a good data interpretation and analysis
Different teams can collaborate and work on the crucial data, as real-time data sharing is enabled in Qlikview.
Qlikview does not demand high-tech application knowledge to operate it. Both, application scripting and dashboard can be handled without much training and any external IT help. Any non-technical employee with a little exposure to the application will be skilled enough to work on it.
The implementation of the application is hassle-free and is simple. It doesn't require dedicated maintenance even in the long run.
Whenever any aggregation, calculation is made on data, the operations proceeds in-memory, while the data will be transferred from back-end to front-end. This saves a lot of storage memory, as the pre-calculated data will not be stored anywhere.
The Qlikview considers only the useful bits of data. It removes all the junk bits and ensures that the data is redundancy-free. Hence, in the process, the data will be compressed to 10% of the original size, which improves the efficiency of data handling by the software.
The QIX engine of the software is sensitive to click. It recognizes every click and responds to it through the process of changing color hues by highlighting the data related to the selected field. This helps in better understanding of the data for the user.
Qlikview allows for both the direct and indirect searches. If you want to fetch some information about data, you can simply input anything related and get results. The result will be prompt in both direct and indirect cases.
Qlikview software is very affordable. The hardware required for the software is also cost-effective. There is also a free trial available in the software.
To create the application for the end user, the technical expertise is needed as the process is quite complex. For things that are at a base level, there is no much training needed. However, with the increase in complex computation, script writing demands pre-knowledge of the software.
The customer support is deemed as poor and unsatisfactory, according to the customer reviews.
If you want to embed the Qlikview software with some other software, things become messy, as this software is quite distinct in appearance.
Qlikview has remained with some obsolete tools and interface designs. It lacks the new methods of drag-and-drop function and other designs which offer cutting edge technology over the normal Qlikview functions.
Having learnt the basics of Tableau and Qlikview, it is important to understand the basic architecture of each of the tools, which allows us to get an insight of the flow of control in each of them.
The following diagram reads the architecture of the Tableau.
The architecture of Tableau follows the famous, highly scalable, n-tier, client-server model. Here, the server serves the web clients, desktop-installed clients and mobile clients. Tableau Desktop is the authorized edition, which is used to create multiple views on the server.
Tableau server is the analytics platform, which is used as an enterprise level, business analytic tool, used to level up thousands of clients.
QlikView architecture is made of the front-end and the back-end. The front-end visualizes the processed data while the back-end provides the security and publishing tool for the user documents.
The frontend is made, mainly of the QlikView server, which is used by the users to view the already generated BI reports.
The back-end mainly consists of the QlikView Desktop and QlikView Publisher. The drag and drop mechanisms can be conducted on the Desktop, while the distribution service is performed by the Publisher.
