Domain Specific Languages (DSL) and Domain-Driven Design (DDD) are two related concepts that have been kicking around the edges of the software engineering world for a few years, but have recently started to move much more towards center stage. A DSL is a language specially geared to working within a particular area of interest: it might be a vertical domain such as telephone design, or a horizontal one like workflow. Some well-known examples of DSLs are HTML and SQL. What is radically new is the idea of creating your own DSL for your own project. Microsoft has actually been at the forefront of promoting the use of DSLs, and has recently announced the Microsoft DSL Tools. The Microsoft DSL Tools will help developers create their own languages more easily, and work together very closely with Visual Studio Team System. This book's authors are the main designers of the Microsoft DSL Tools. They've written a book that is straightforwardly focused on understanding and using these tools; it intends to provide a detailed yet readable reference to the tools.
About the Author: Steve Cook joined Microsoft in 2003 to work on the DSL Tools. Previously, he was a Distinguished Engineer at IBM, which he represented in the UML 2.0 specification process at the OMG. He has worked in the IT industry for 30 years, as architect, programmer, author, consultant, and teacher. He was one of the first people to introduce object-oriented programming into the UK, and has concentrated on languages, methods, and tools for modeling since the early 1990s.
Gareth Jones is a lead developer in the DSL Tools team. He's been at Microsoft since 1997 doing various developer jobs such as building bespoke enterprise solutions, running the development of Microsoft UK's small business portal, and managing a consultancy team. Before joining Microsoft, he spent seven years leading development projects in the intelligence analysis, simulation, and aerospace industries.
Stuart Kent joined Microsoft in 2003 to work on the DSL Tools. Previously, he was an academic and consultant, with a reputation in modeling and model-driven development. He has over 50 publications to his name and made significant contributions to the UML 2.0 and MOF 2.0 specifications. He is a member of the editorial board of the journal Software and Systems Modeling, and on the steering committee for the MoDELS series of conferences. He has a Ph.D. in computing from Imperial College, London.
Alan Cameron Wills was a methodology consultant for almost a decade, and used to get very frustrated when people asked about good tools to support the methods. So he was very pleased to join Microsoft in 2003 to help in the DSL Tools project. He has a Ph.D. in computer science, and was joint creator of the Catalysis approach to component-based development. He gets excited about software factories, photography, sailing, and hills.
