situations are also varied In some cases, raising the level of abstraction is an adequate bene t itself In others, complex relationships must be maintained, and a graphical DSL brings order and visual understanding to data that would otherwise need more expert interpretation even if the abstraction level is only minimally affected Nonetheless, it is still true that software systems are principally developed in a world where the simple text le dominates Whether to store source code, or to persist a scripted means of setting up the data in some more complex piece of software or database, the ability for a set of text les to be managed together in a single version control system means that this style of working is unlikely to disappear for some time; indeed, the rise of XML as the de facto standard structured data representation language has probably ensured the endurance of this approach for the foreseeable future Consequently, the single most important transformation that can be applied to a DSL is to produce another artifact as a simple text le, whether that is source code, database script, or the persisted representation of a different DSL We can see this clearly at work in our example from 2 If we examine the scenarios around the IssueProject DSL, we can see that there are two primary pieces of artifact generation applied to it First, code is generated to improve the domain-speci c API for manipulating Issue data within the database We ll look much more deeply at how that is achieved in this chapter Second, scripts can be generated from this DSL to populate a production SQL Server Issues database with the settings described by a particular instance document This is an interesting case, because the DSL also has custom code added to it to allow a database to be con gured directly from the tool Why would a DSL provide two such apparently redundant methods of working The answer is that although the direct database connection-based tools are convenient for running a quick test or updating a staging version of a database, it is unlikely that the user of a DSL would have such direct access to a production server It would also not be sensible for an organization to operate without a scripted install for a database that was important to its working practices in order to be able to build servers from scratch The generation of such scripts for administrators thus complements convenience tools aimed more at developers, and is a useful pattern

Extensible Stylesheet Language Transformations One method is to simply transform the persisted representation of a DSL directly to the desired artifact Given that DSLs are typically persisted as XML, the natural tool for this task is XSLT Here s a fragment of a class design DSL:
