Traditional BI solutions are powerful and can provide scaling and reliability. Various well-established software firms have endorsed them. These solutions provide ample security for data. Although, they need good BI technical knowledge and skills to work with them. Oracle BI and Qlikview are just two simple tools used among them.
Tableau is one of the top BI tools used in the industry today, providing easy operation and understanding without much knowledge of BI competencies. It has simple drag-and-drop functionality and a smart way to categorize the fields of data. However, in Tableau Public, data security is not provided, while in the Professional version, security is enabled.
