No programming, only insight. The user can easily create their own perception using various objects and it's easy to use because of a well designed GUI interface. Tableau offers a storytelling feature that can allow us to create a presentation using data points that are available. It does not provide a feature to search content across all the user's dataThe best quality of Qlikview is it's easy to use the feature and even exploring the hidden trends.QlikView offers an associative technology that enhances the capacity of the presentation. This feature helps companies understand hidden links between data points. In the case of searching any data, we just need to type the word in the search box resulting in instant and It also shows in-depth connections and relationships across the data. At times it becomes difficult for users to design their own views due to properties that are menu-driven.Ease of LearningTableau has community and resources which are actively engaged. The drag & drop application even makes it very easy to learn for the end-users.QlikView also has actively engaged community and resources which ultimately helps the user learn this software in the best possible way.CostTableau: Here are Tableau’s new monthly prices: Tableau Desktop Personal, $35; Tableau Desktop Professional, $ 70; Tableau Server, $35; and Tableau Online, $42. Under the old model, a license, with annual maintenance, costs $999 for Desktop Personal and $1,999 for Desktop Professional.

Today, companies are investing more in information segmentation, clustering, and stronger analysis. It offers a user-friendly interface that enables even non-technical users to generate tailored dashboards rapidly and easily to give significant perspectives in a wide range of company data.QlikView, on the contrary, offers normal report creation characteristics, visualization templates, configurable graphs, and customized opinions that assist provide an interactive report in real-time. All the visualizations and data sets are shown as a quick reference when QlikView is in use. Qlik's product provides an in-memory engine that can view patterns and produce associative analytics that alone can not be achieved with SQL. The In-Memory Engine is able to integrate with diverse information source variants and create a unified dashboard that shows analyses, KPIs and metrics of our concern.Connectivity with Other tools/ Language or DatabaseTableau integrates successfully with a wide range of data sources which includes the spreadsheets, CSV, SQL databases, Salesforce, Cloudera Hadoop, Firebird, Google Analytics, Google BigQuery, Hortonworks Hadoop, HP Vertica, MS SQL Server, MySQL, OData, Oracle, Pivotal Greenplum, PostgreSQL, Salesforce, Teradata, and Windows Azure Marketplace. It can also coordinate with sources of Big data as well.Qlikview also integrates with high range of data sources like Amazon Vectorwise, EC2, and Redshift, Cloudera Hadoop and Impala, CSV, DataStax, Epicor Scala, EMC Green Plum, Hortonworks Hadoop, HP Vertica, IBM DB2, IBM Netezza, Infor Lawson, Informatica Powercenter, MicroStrategy, MS SQL Server, My SQL, ODBC, ParAccel, Sage 500, Salesforce, SAP, SAP Hana, Teradata, and many more. In this case, API integration can be used to connect with R. It can also readily connect with Big data sources.DeploymentSince tableau does not have their own data warehouse hence they have to generate layers while connecting with data set. The deployment becomes easier here since it needs more structured data.QlikView has its own data warehouse with an additional feature of scripting which acts as a feature in the cap leading to the use of multilevel layers in its deployment. QlikView is readily deployable and configurable and starts producing excellent reports immediately after the installation. An additional feature involves enabling interactive queries and creation of reports—a technology which is not found in other products since this product does not use cubes; hence loads all the tables and charts found in the memory. Both 32 and 64 bit can be used for the development. Data modeling becomes easier because of associative technology.SpeedIn the case of Tableau the speed varies based on two parameters, first being the RAM and second being the source's database. Tableau makes it extremely effective to produce in a matter of minutes of interactive views and reports. Tableau can also speed up the entire process since it enables online and offline report sharing. In Quikview the Speed is dependent on only the source's RAM.QlikView offers quick assessment, outcomes, and allows for much quicker decision-making in comparison to traditional techniques.Valuable Insight GenerationTableau has an excellent storytelling feature that helps the user to create effective presentations, using the available data sources.In Qlikview the Associative technology makes it more impressive and it also helps to read association between variables readily. This unique feature sometimes even benefits businesses to understand the hidden relation between the data points.MobilityTableau is readily available on all devices and can be accessed via the internet. We can even use it on our laptop, tablet or smartphones as well.QlikView is independent of any device thus we can easily access it from anywhere hence decision making becomes much prompt and quicker as compared to the traditional methods of data visualization.SecurityTableau provides excellent security features and it is highly handled by Tableau server. It is indeed a modern enterprise analytics platform that enables the users to avail the self-service analytics at scale with proper governance. Security is the first and foremost critical part of a data and content governance strategy. It's server actually provides comprehensive features along with deep integration to address all the aspects of enterprise security present. Tableau also renders the organizations in promoting trusted data sources for all users, so the right data is used to make the right decisions within seconds.PerformanceWhen compared with Qlikview, Tableau generates the output slower since it uses the cubing technique for data visualization. QlikView seamlessly combines all sizes of datasets hence are quicker when compared with Tableau.ScalabilityQlikView is a lot more scalable than Tableau. The Qlik Sense applications can be easily scaled especially while dealing with big data. But we cannot deny the fact that both the vendors handle a huge amount of data successfully. In Fact, most of the organizations do not produce the amount of data that both these can handle individually.Big Data SupportTableau has good support for Big data as compared to Qlikview.CustomizationSimple drag and drop features are available in Tableau. Qlikview is Complex tools when compared with Tableau.ConclusionIn brief, the reply to the question:' Which is the best tool for data visualization? It's pretty subjective. Users find out the demands of their business or their projects, which is a matter of personal preference. In both Tableau and QlikView, all the points listed above in this blog illustrate the possible regions where consumers can assess and comprehend their possibilities and then decide in an informed fashion which ones to use.Want a career in Tableau and QlikView? Then taking up training in Tableau and QlikView would be an added advantage.

Before going into details for installation, it is important to understand the various components of the Tableau software suite. There are six different components of Tableau:Tableau Server: It serves the purpose of a centralized repository for dashboards and data sources used in any organization. Tableau desktop publishes dashboard and data sources on the Tableau server. Tableau Server is a key component for control and compliance perspective as well. Industry-specific compliance requires to have an on-premises version of the server to have physical control of the content. This is important for auditing purposes. Tableau server also easily integrates with windows active directory which helps in enabling single sign-on for organizations as well.Tableau Desktop: This is the main component used by developers to create interactive dashboards and workbooks. It can connect to any data source and does the transformation required to meet the business needs of customers. We can add customized filters and also do some additional calculation while creating dashboards in Tableau desktop.Tableau Public: This helps users to publish their dashboards on Tableau public server hosted and owned by Tableau software. Any organization/individual can create their public profile on Tableau software and leverage that profile to publish local dashboards.Tableau Reader: This comes as a free offering from Tableau to view and interact with dashboards created by Tableau desktop.Tableau Online: This is a cloud-based offering from Tableau. Any organization who does not want to have a tableau server hosted on-premises, can go with Tableau online.Tableau Mobile: This is available as both android and iPhone apps. We can use this app to view dashboards if we have Tableau online subscriptions or user access to organizations Tableau server.Key FeaturesOther FeaturesOperating SystemLicenseTableau DesktopCreates dashboards and stories locallyTableau Personal: limited data sources, non-connectivity to Tableau Server.Tableau Professional: Full enterprise capabilities.Windows, MacPersonal: $999Professional: $1999Tableau PublicA massive, public, non-commercial Tableau ServerAll data published in public-FreeTableau OnlineCreating Dashboards and stories on the CloudLive connections-$500 per yearTableau ReaderView dashboards and Sheets locallyCannot modify workbooks or connect to the serverWindows, MacFreeTableau ServerConnect to Data sources and share DashboardsUsers can directly interact with Dashboards via a browserWindowsCore LicensingWe are going to cover installation for Tableau Server and Tableau desktop in detail here.Tableau server Installation on WindowsTableau server can run on a multi-node cluster as well on Virtual machines as well. Here we will be covering installation on a single-node machine.The minimum hardware requirement for Tableau server(Single node) :Processor speed: 8 core, 2.0 GHz or higher processor32 bit/64 bit architecture: 64-bitRAM: 32 GB memoryHard Disk: 50 GB disk space should be availableOperating system requirements :The operating system which supports Tableau server installation are as follows: Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, Windows server 2019, CentOS 7, Ubuntu 16.04 LTS, Red Hat Enterprise Linux (RHEL) 7, Oracle Linux 7Installation Path: The Tableau server gets installed in the system drives where windows operating system files also exist. If by default, the system drive is the C drive, then the installation path will be as follows:C:\Program Files\Tableau\Tableau Server\packagesC:\ProgramData\Tableau\Tableau ServerSome organizations install tableau server on different location as well. We can provide the location different than the system drive by browsing install location which will automatically add \Tableau Server to it and will install the files under it.Let’s now go to installation for version (2018.2) of Tableau Server.Step 1: Get the product key of the software using the user id and password that you must have received while purchasing Tableau. Then go to the Customer Portal and get the product key.Step 2: Get the Admin rights for the computer on which we are installing Tableau software. The developer should be a member of the administrator's group in local users and group management.Step 3: Get the installation files for Tableau server. We can download installation file by visiting Download Tableau Server-WindowsStep 4: Run the installation files with admin rights, the below screen will come up where you can change the installation drive, by default it will be installed in system drive:Step 5: Once we click next, the below page will appear where we can choose installation type, in this article we will be covering new Tableau server installation:Step 6: After we click on the install button, the installation process will be kicked off and once the installation is completed clicking next will start Tableau Service manager. It may take some time to start TSM.Step 7: Once TSM process gets launched by a setup process, the below screen will come up. We need to log in using the same admin credential which we have used for running installing set upStep 8: Once we login to TSM, it will ask for a product key to activate the tableau server:The product key is used to activate both server and setting license type which can be user-based or core-based. It requires an active internet connection but there is an alternative way to activate tableau offline as well. You can read Activate Tableau OfflineStep 9: The next step is configuring the basic settings on the Tableau server after activation and successful registration of product key. We can set how we want to authenticate users either local or active directory, setting under which account tableau server should run, setting default port and whether we want to include sample workbook or not.Step 10: Setting the authentication type is very critical in the entire set up. By default the authentication type is local. The other option is active directory authentication. If we select an active directory option, then we need to enter a domain name in the fully qualified name and in the NetBIOS section we can enter the domain’s nickname:Step 11: We can run Tableau server either under NT AUTHORITY\NetworkService or custom service account. We need to provide a domain name with the user name for the custom user account.Step 12: Setting default port for Tableau server: By default, it takes port number 80 if there is no other application running on the same port. If the port is not available, we need to find out which other application has claimed port number 80. Usually, IIS runs on the same port. IT infrastructure team can help us in getting a new port if 80 is not available:Step 13: Once we click on the initialize button in step 9, Tableau server will start saving all the configuration settings set in previous steps :Step 14: Once the initialization gets completed, the below screen will appear and clicking on the continue button will take you to the final step where you need to configure administrator user for running Tableau server:Step 15: Tableau server set up at last step launches a browser and opens a page where we need to set administrator user for Tableau server. The administrator does take care of all tasks like managing sites, users administration, groups and project management. Even for changing, any configuration setting can be done only by the administrator. In the case of active directory authentication, the administrator must belong to a user in the same directory. For local authentication, we need to provide a username and password. This account is very critical as it provides a single entry point to Tableau server in case of any issue in server.Step 16: Once we are done with the setting of administrator users, we can log in to the Tableau server using web interface. We can then start publishing the workbook to the server using Tableau desktop.Tableau server Installation on Linux/Ubuntu:With the growing demand for Tableau server running on Linux/Ubuntu, it is now supported on Linux as well. In a recent survey, it has been found that 25% new server installation happened on Linux server. Let us now cover the step by step process for installing Tableau Server on Linux :Download the Linux version of Tableau server as per the operating system. In this article we will cover tableau-server-2019-1-1_amd64.deb (1371 MB)Only the below version of Linux are supported Red Hat Enterprise Linux (RHEL) 7.3 and higher, CentOS 7.3 and higher, Oracle Linux 7.3 and higher, and Amazon Linux 2.Version.The latest versions of Ubuntu 16.04 and 18.04 LTS only. Non-LTS releases are not supported. The installation tasks will be run as root. We can run this by Sudo command or we can run commands directly as the root user.Log in with the user having Sudo access to the system and navigate to the location where you’ve copied the installation package. Now you will be using the package manager to install Tableau Server. We have different commands for RHEL and Ubuntu:On RHEL/CentOS we can have below commands sudo yum update sudo yum install tableau-server-.x86_64.rpm On ubuntu we can run below commands sudo apt-get update sudo apt-get -y install gdebi-core sudo gdebi -n tableau-server-_amd64.debNext step is initializing TSM. We need to navigate to script location:cd /opt/tableau/tableau_server/packages/scripts.If the system is connected to the internet, then we can run the command given below to start TSM: sudo ./initialize-tsm --accepteula and in case of a system connected to the internet through the proxy server, we can run the given below command:sudo ./initialize-tsm --accepteula --http_proxy=http://proxy.example.lan:80/ --https_proxy= http://1.2.3.4:443/In the above example, we can replace hostname proxy .example.lan and IP address 1.2.3.4 with our hostname and IP address.Once initialization is completed, we can close the terminal sessions: logoutNext step is activating and registering Tableau server. Navigate to web UI interface for TSM Web UI. In case of an authentication error, check if the user belongs to the tsmadmin group or not. It can be easily checked running following command in bash:grep tsmadmin /etc/group - this will list down all users belonging to the tsmadmin group. We can also add the user to a tsmadmin group by running the below command: sudo usermod -G tsmadmin -a . Once we added the user successfully we can run tsm login command.After successful login to TSM, you can activate the key :Once License activated, we can enter basic information and click on the register button as below :The next step is configuring basic settings like authentication, port etc.If we opt for active directory, then there are two options to connect either using simple bind or GSSAPI bind:Once initialization is completed, the below screen will come up to confirm it :Next step is creating administrator accounts for Tableau server. If we have used an active directory authentication, then we can run the below-given command to create the same :tabcmd initialuser --server 'localhost:80' --username ''.In case of local authentication we can create a custom user who will be working as admin using below command: tabcmd initialuser --server 'localhost:80' --username 'admin'We can then check firewall settings which is an optional step but it is best to practise for security. There are two ports on which Tableau server run. The first port is a gateway port(80) and the other one is tabadmincontoller port(8850). Please find below commands to open these ports :Starting firewalld by sudo systemctl start firewalldSetting default zone as public by running command sudo firewall -cmd --set-default-zone=publicAdding ports for the getaway port and tabadmin controller port by running commandsudo firwall -cmd --permanent --add-port=80/tcpsudo firwall -cmd --permanent --add-port=8850/tcpLast step would be reloading the firewall and verifying settingssudo firwall -cmd --reloadsudo firwall -cmd --list-allThe final step is validating Tableau server installation by installing the PostgreSQL driver which can help in viewing administrative views. First of all, you need to download the driver by navigating to Driver Download page. Once the driver is downloaded, you can install it by below command :CentOS and RHEL ,we can download the .rmp and run below command :sudo yum install tableau-postgresql-odbc-9.3.1.x86_64.rpmUbuntu need .deb file and below command :sudo dpkg -i tableau-postgresql-odbc-9.3.1.x86_64.debOnce the driver is installed, you can validate by visiting Administrative Views in tableau server.Tableau desktop Installation on WindowsThe first step is downloading installation files from Tableau Desktop DownloadRun the .exe file once the installation file is downloadedOnce you click the run button, the below screen will appear, you can read the license agreement and confirm the acceptance to proceed furtherOnce the installation is completed.
