Ajan's BI Blog

In the previous blogs I was more focused in Power BI since i work with it day to day, but this time we are going to dig into increasing the usability features of tableau. This blog revolves around the end-user simplicity, if a model is hard to comprehend then it will be a disaster, so we should deploy some means to stay simple. So without further ado lets head on to the first topic of the day. Configuring table and  column  properties. A model can consist of many tables but the important fact is they have to be unique and it is better if we can have a table description to elaborate on whats it about. This can be also considered as an internal documentation, when a project member is changed it is easy to pick up and continue. We use connections to load data for the tables and we have a connection name for it but once if we set the source it cannot be changed in the latter part, so be mindful because once you are dropping a connection you are losing all th...

Hologram is a technology of creating a three-dimensional image formed by the interference of light beams from a laser or other coherent light source. An interference pattern of photographs which are properly illuminated can create a 3 dimensional effect. This can lead up to the extent of creating 3 dimensional dynamic images which can be observed by bear eyes without the assistant of glasses or any other visual aids. A simple simulation of creating a static 3 dimensional hologram can be done with our smartphones, all we need is 1.        A transparent Pyramid which is made of glass or plastic.  2.        Four images placed in the vertices of a square which are properly illuminated by phone's screen brightness. 3.        Ambient light or low light area to view the hologram without noise. Then you can see the magic. Hologram is a game changer, for an example i...
