Biography of Martin Fowler
In the year, he graduated from the University College of London. In the year, he moved to the United States, where he lives near Boston, Massachusetts, in the suburbs of Melrouz. Fowler began working with software in the early xs. After graduating from the university in the year, he began to develop software in Coopers AMP; Lybrand up to a year. In the year, he joined ThoughTworks, a company on systemic integration and consulting, where he holds the position of chief researcher.
Fowler wrote nine books on the development of software development, see the AGILE Alliance member and, together with 16 signed parties, helped create a flexible development manifesto development of software in the year. It supports glare, a mixture of blog and Vika. He popularized the term "introduction of dependencies" as a form of control inversion.

Kent Bek and Martin Fowler. They say that DSL is defined as an composite programming language, focused on a separate area and having expressive restrictions. It is claimed that DSL can increase performance by eliminating the requirement from the programmer to understand the full language of programming, providing means of communication with experts in the subject area and separating the method of performing the task from determining the task itself.
These advantages are compared with the costs of learning a new language and creating tools for this language, which leads to the fact that different languages and abstractions used in DSL are not suitable for solving a specific problem. Fowler introduces the concept of internal or built -in and external DSL, and the internal DSL is DSL, which is a subset of another language and can be performed by tools for this external language.
Ruby and Lisp are given as examples of languages in which internal DSLs are widespread. He also introduces the idea of a semantic model that determines the execution of DSL. Various DSL examples are presented, including Graphviz, a language for determining graphs that should be displayed; JMOCK - Freimvork for fixing Java; CSS - language for determining the stylistic elements of the website; HQL - object -revolutionary converter in Java; XAML - a language used to determine and change graphic user interfaces; Fit, language for expressing testing scenarios; And to make a tool for creating software in the book discusses the implementation of external DSL using tools such as syntactic analyzers, lectures, abstract syntactic trees and code generation, called the “syntax -based translation”.
This contrasts with the “division on the basis of dividers”, which is considered a simpler, but less powerful. Here the language is simple enough so that it can be interpreted by separation by separators and switching logic based on individual records.
Ways to implement internal DSLs with paying attention to the challenges of the invested functions, sequences of calls of functions or chains of methods among other methods.
