On Design of Domain-Specific Query Language for the Metallurgical Industry

Many systems have to choose between user-friendly visual query editor and textual querying language with industrial strength in order to deal with big amount of complex data. Some of them provide both ways of accessing data in a warehouse. In this paper, we present key features of domain specific querying language, which we designed as a part of informational system of a steel production plant. This language aims to give an opportunity of easy data manipulation to those who know what the data actually is and to provide an easy way to discover what the data is for others. We also provide an evaluation of the designed language. The main focus of our estimation was to measure effort required for discovering dataset and deriving simple math expressions. Although the paper overviews a data model for one specific domain, it can be easily applied for different domains.
