DSL for database concatenation and migration

Abstract

DSL or domain-specific language is a programming language to a particular domain or a particular solution technique. Sometimes can occur the need to concatenate two or more databases and after to migrate the data. The article will not study the causes of concatenation but the solutions for achieving it. Though it sounds simple the process in a real world scenario is a complex one with lots of dependencies. It is analyzed some examples on which typically solutions are proposed. The DSL for solving such tasks is not described, instead its requirements and its goals are.
