  • Performance Issues
    For very large datasets or complex calculations, Tableau can experience performance slowdowns, affecting the efficiency and user experience.
  • Steep Learning Curve for Advanced Features
    While basic features are easy to use, mastering advanced functionalities can require a significant learning curve and technical expertise.

    Although Tableau is highly customizable, some users find it lacks flexibility when it comes to very specific or unique customization requirements.
  • Export Limitations
    Exporting visualizations and dashboards to formats like PDF or PowerPoint can sometimes be restrictive, limiting the ways reports are shared.

OpenSilver features and specs

  • Cross-Platform Compatibility
    OpenSilver enables developers to create applications that run on multiple platforms, including web browsers, by leveraging WebAssembly, which enhances the reach and accessibility of applications originally written in Silverlight.
  • Silverlight Code Reusability
    Since OpenSilver supports C# and XAML, much of the existing Silverlight code can be reused, minimizing migration efforts and reducing time and costs associated with redevelopment.
  • WebAssembly Based Performance
    By utilizing WebAssembly, OpenSilver applications can achieve near-native performance, leading to efficient and responsive user experiences in web applications.
  • Open Source Flexibility

  • Integration with Modern Web Technologies
    OpenSilver allows integration with modern web technologies and frameworks, enabling developers to enhance applications with contemporary features and functionalities.

Possible disadvantages of OpenSilver

  • Incomplete Feature Support
    Not all of Silverlight's features are fully supported in OpenSilver, which might necessitate additional workarounds or re-implementations for complex applications.
  • Learning Curve for Migration
    Developers familiar with Silverlight may need to learn new patterns and practices related to web development and WebAssembly when transitioning to OpenSilver.
  • Browser Compatibility
    While WebAssembly aims to be universally compatible, some differences in performance and behavior might occur across various browsers, potentially requiring additional testing and optimization.
  • Community and Support Maturity
    As a relatively new and open-source project, OpenSilver might have a less mature support ecosystem compared to more established platforms, impacting the availability of resources and community support.
  • Dependency on WebAssembly
    OpenSilver's reliance on WebAssembly means that any limitations or ongoing development challenges associated with WebAssembly could directly impact the capabilities and performance of OpenSilver applications.

  1. MeganMills
    Powerful Data Visualization Tool with a Steep Learning Curve

    Iโ€™ve used Tableau to analyze and present data for business reporting, and its strength is clearly in visualization. Turning raw data into interactive dashboards is fast once you understand how the tool works, and the end results look polished and professional.

    However, getting to that point isnโ€™t instant. New users may struggle with calculations, data modeling, and performance tuning. Licensing costs are also high, which can be difficult to justify for smaller teams or individual users.

    Tableau works best for organizations that rely heavily on data-driven decisions and can invest time and budget into analytics. Itโ€™s not the easiest or cheapest option, but the output quality makes it worthwhile

  • Tableau Certified Data Analyst Exam Readiness
    Hey everyone, I'm interested in taking the Tableau Certified Data Analyst Exam Readiness course through tableau.com to prepare and get Tableau certified. I had some questions about the course, such as are the videos pre recorded or in person, do you have access to the material once the 90 days expire, and I was also wondering if anyone had input/advice for this course. Thanks! Source: about 3 years ago
  • Where to publish knowledge sharing on Tableau reverse engineering and data dictionary generation?
    Could anyone recommend what media I should approach to publish my work (internet or print). I could try the Tableau forum in tableau.com but it's not very active + Tableau may be unappreciative as my work overlaps with their (pricey) data management solution. Plus it needs to be some high visibility / reputable media to count for my career development. Any recommendations welcome thanks!!! Source: over 3 years ago
  • I have huge loads of data in Redshift. How can I make this available to end-users after performing few procs and queries? It should be available online.
    Tableau public: tableau.com. Big player but your data will be made public and not really user-friendly data model. Source: over 4 years ago
  • What tips do you have on evaluating various BI tools for business needs? What are the essential criteria's you would include when evaluating different tools? The goal is to have an unbiased, objective approach.
    For example, we have a project to compare Tableau, Power BI, and InetSoft. The need for strong pagination-based email delivery eliminated Tableau. AWS's Linux instance is the targeted platform which makes Power BI less than ideal. Source: over 4 years ago
  • Anyone go into Data Analytics after this program?
    I just started learning Tableau because our dept is transitioning into Tableau from Power BI. Since I already have years of experience with Power BI I just went over their tutorials from tableau.com and got onboarded pretty quick. I'm still learning it but I'm at least able to build out reports and get things done. Its not too difficult to pickup one BI tool when you have experience with another. Source: over 4 years ago

    I would also say that IF blazor worked on a browser plugin like silverlight did, today that's not the case it is built on the webassembly standard which and it is being adopted in the browsers which means once it gets on the web, it is unlikely to ever go out again.
