What do you like best about KX?

I use KX's kx-dashboard product to create user reports/dashboards, I found it very easy to create the user reports/dashboard using ox-dashboard.

In our organisation we have moved from a very well-known dashboard creation product to kx-dashboard. As we found it is faster and has a few better functionalities like breadcrumb and pivot data grid.

I have also created this video to showcase how we can create a real-time dashboard using the ox product. Review collected by and hosted on G2.com.

Steep Learning curve.

For learning KX kdb it does take some time Review collected by and hosted on G2.com.
