Abstract
End-user interaction with data is one of key aspects in data processing. Nowadays a lot of information systems have a custom made user interface for data input and data querying. From 1970s it is envisioned that a generic, user-friendly approach for data querying could be built, but no wide spread solution has been developed. In the paper we present a diagrammatic query language. We have done an iterative approach to design and improve the diagrammatic query language to make it user readable. Readability is analyzed with questionnaires. Readable diagrammatic query language is the first step to create a more generic and user-friendly data querying.
