Tableau

Kommentare: We used Tableau for Visualization BI apart from having Business Objects for reporting. We have created a story for a given subject with all the related information to present to the user. It gives a quick glance on what is happening on the sales of drug for a pharma company that I worked. Migration from non-prod to prod is very easy (unlike other BI tools). Cost of the project reduces a lot with Tableau for BI projects

Vorteile: Tableau has changed the BI world a lot. It has brought in a software, using with business user can create dashboard & reports on the fly and can check what is there inside. It allows the user to read through the data and derive the insights without much technical analysis. First it can connect to any database (I know about 44 database it connects) and you can set the data, slice the data needed for current analysis and then you can do quick reporting. It provide multiple features, like different charts, graphs and tables and mathematical and statistical functions for analysis. Once you have create multiple visuals you can put them onto one dashboard or multiple dashboards into a story and present the same to business

Nachteile: Even though it has rich features but it can support the Enterprise BI needs like business object or Cognos does. It does not provide all the feature for E L T (extraction, load and transform) which requires complex transactions. As data gets huge the graphs and charts become unreadable. also, this software is more useful to the business user for personal purpose than company wide reporting etc. The administration part of it needs a lot.

Kommentare: Tableau and especially Tableau server has helped our business share data much more efficiently and accurately than the old method of emailing spreadsheets and presentations around. The ability for anyone to manipulate the data and answer their own questions allows analysts to concentrate on the truly difficult and unique problems instead of cranking out a never-ending series of custom reports. Having the data connected to live source or warehoused data means everyone is up to date all the time.

Vorteile: Tableau is exceptionally easy to pick up and be productive, and has the ability to connect to almost any data source you can imagine, including REST APIs (though this is a pretty advanced process). Cross database joins are an amazing feature that allow you to mix data from Excel, Oracle, MySQL and others on a single dashboard. There are a ton of online resources available from Tableau, and the broader user community which help you in the event that you get stuck on a thorny issue. Tableau also supports the Tableau Public desktop software which allows anyone to create and share visualizations for free on the web (though data sources are severely limited with Tableau Public).

Nachteile: Price is an issue, particularly if you're an individual or a small business. Woe be unto you if you're a small business and you'd like to set up a Tableau server. There are some functions which we've all grown accustomed to in Excel which new users will expect to be in Tableau but just aren't--robust Conditional Formatting, for instance. However, in most cases there are workarounds and other ways of accomplishing the same task. While it's easy to become quickly productive, most users will outgrow the easy stuff pretty quickly as they attempt join new data sources, or produce more complicated visualizations.
