An enterprise is having bulks of data to transfer and make changes on a daily basis required huge storage, fastest network, and large servers. In this fastest era of technology, the end user who uses the data requires the data to be accurate giving answers to his questions in a better way.
There Comes the use of Data Visualization. Tableau Desktop from Tableau is on such a data visualization tool that automatically converts data from the database and creates graphical representation and also acts in a reverse way of converting images into data.
There is no need for any technical resource to sit and write long codes. Data shared is all highly secured as it is shared on a single cloud-based common library. The enterprise can integrate with other data management tools that already exists with them using drag and drop mechanism.
We have already said bye bye to many computers asserts right from floppy disks to CD/DVD. Similarly, enterprises also said goodbye to old spreadsheets, graphs, and charts, etc. We have shifted from 32 bit to 64 bit operating system.
Tableau Desktop does things differently.
Rather than using a long query to get the required information visual, Tableau uses drag and drop functions to make more accurate and sophisticated visualizations on Data called VizQL.

Four server processes handle the entire work of Tableau:
1. Application Server:
2. VizQL Server:
3. Data Server:
4. Gateway/ Load Balancer
Application Server processes file- wgserver.exe that handles the browsing and data access permissions for the web and mobile interfaces.
When a user wants to view the data, a server checks for the user access permissions and then allow viewing. Once a file/data is opened, the client sends a request to the VizQL process a file vizqlserver.exe.
It then sends queries to the data source that is centrally managed and maintained with metadata. When it is passed to the Gateway Server, it routes the client requests to another client system that can be desktop, mobile or computer.
