Real-time event streams editor

What we were working on

An low-code editor enabling SQL users to filter out meaningful events for further processing in business applications.

Providing a simple method for SQL users to define conditions to detect events in real-time data streams, so that they can act as triggers for automated processes that enhance omni-channel customer experiences.

What I did

  • Translate SQL data manipulation methods into visual metaphors
  • Design original icons to represent the methods
  • Align icon style with the style defined for the ETL editor I previously designed
  • Defined color encoding for three distinct processing phases (I/O, and processing)
  • Design layout algorithms for splitting and joining operations
  • Designed interactions for gesture input on surface computers and touch devices


An intuitive method for capturing events relevant to the business for further processing in business applications.
