What are the disadvantage of tableau?

Answer 1

Among the many data visualization products on the market, Tableau Software is by far the most popular. More than 16 years of unrivaled user experience have been offered by this application for transforming raw data into useful insights.

The drawbacks of Tableau's application

Despite Tableau's enhanced visualizing and designing skills and other advantages, there are a few limitations to be aware of.

1. Expensive

When compared to Oracle and IBM, Tableau isn't the most expensive data visualization software out there. But there is no denying the fact that the Tableau license is expensive for most small and medium-sized businesses, making it a significant drawback. In addition, the software requires extensive implementation, implementation, maintenance, and training costs. Due to its expensive price, Tableau is mostly used by large corporations.

2. Fixed-priced

Tableau's salesforce lacks the ability to tailor their approach to each customer's unique needs. In spite of the fact that each organization has a unique set of visualization needs, Tableau's sales methodology forces clients to purchase the extended license from the beginning. Many firms that use Tableau have concluded that they don't need all of the capabilities that they've paid for. They'd rather buy all the ones they'll need up front and then scale them down as needed.

3. Poor Post-Sale Service

Many Tableau users have expressed their dissatisfaction with the company's post-sale support. Customers that have a software performance issue aren't fixed by the support team analyzing and eliminating the problem's source. The best they can do is recommend that users buy an add-on to make up for the flaws in their software.

4. Security Concerns

Security is a major concern for visualizing solutions, as they deal with sensitive information. No centralized data security is provided, despite Tableau's strong concern for data safety. It only provides row-level security, which mandates that each user has a unique credentials. The likelihood of the system being hacked increases exponentially as the number of accounts grows.

5. IT Support for Appropriate Use

Tableau, despite its ease of ordinary use, nevertheless necessitates the intervention of an IT department for its further configuration and enhancement of its fundamental functions. In order to perform several tasks, SQL queries must be written by a professional developer. However, despite the fact that unskilled business users may benefit from the service, they will not be able to maximize its potential.

6. Lack of BI Capability

In terms of full-fledged business intelligence, it lacks features like large-scale reporting, data table construction and static layouts.

It also has a limited ability to share results. It has a minimal notification system, and only administrators may set up email subscriptions for end-users. It's possible to set robust trigger-based notifications using a Python script, but the vendor does not support it.

7. Poor Version Control

Reverting to an earlier version of Tableau is not possible for versions older than those that allow revision history.

8 Embedding Issues

In spite of the vendor's claims, the solution's capabilities do not allow for an easy integration into any enterprise IT landscape. The integration of Tableau into a company's product is extremely difficult, both financially and technically.

9. Time and Resource Consumption Training

Tableau expertise is not required for the most basic functions of the application. However, the tool's visualization potential is practically limitless, but the learning curve for non-analyst users is quite steep. It's nearly impossible to learn all of the tool's features without extensive personnel training. It may take weeks or months just to get the hang of using a new tool and reaping the rewards that come with it, whether you're developing it or using it yourself. Additionally, the cost of ownership goes up a lot.

Answer 2

One disadvantage of Tableau is that the calculation in-memory engine is weak. The two demo databases in standard Tableau desktop installation have only 4'248 and 8'399 records respectively.
