- Very easy and fast to build dashboards, compared to many other BI tools
- Has connectivity options to various data sources
- Good community support and very useful free training videos
Clients are pleased with the beautiful and interactive dashboards. They are also happy with the noticeable shortening in time to production.
If it had a semantic layer, it would be great. I know Tableau is not meant for data modeling but the data warehouse is not always perfect. Without a semantic layer, we need to reach out to the ETL team for even small data model changes.
Also, a semantic layer would have allowed for building 'subject areas' by grouping tables and defining joins. This would then allow users with appropriate permissions to build ad-hoc reports without having to worry about table joins.
I have used it for 1.5 years.
We did not have any issues with deployment, stability and scalability. We deployed Tableau Server in the AWS cloud.
We have contacted customer support few times and the support team always came back with solutions / work-arounds promptly. So, customer service and technical support is good.
We evaluated a few other solutions, but we chose Tableau because of the speed with which we can build reports, the simple deployment (cloud), easy scalability and the cost factor.
Initial setup was straightforward and in fact very simple.
An in-house team implemented it, but we went for AWS cloud-based deployment, which was not complex.
Try the trial versions and explore all of the features before going in; it is very useful. Also, the training videos on their website are good.
