Domain-specific languages in practice: A user study on the success factors

Abstract

In this paper we present an empirical study on the use of a domain-specific language(DSL) in industry. This DSL encapsulates the details of services that communicate using Windows Communication Foundation (WCF). From definitions of the data contracts between clients and servers, WCF/C# code for service plumbing is generated. We conducted a survey amongst developers that use this DSL while developing applications for customers. The DSL has been used in about 30 projects all around the world. We describe the known success factors of the use of DSLs, such as improved maintainability and ease of re-use, and assert how well this DSL scores on all of them. The analysis of the results of this case study also shows which conditions should be fulfilled in order to increase the chances of success in using a DSL in a real life case. © 2009 Springer Berlin Heidelberg.
