It s interesting to look into this solution and see where the name of the web service StockPrices appears There are several places, in fact, including: 1 The name of the le StockPricescs 2 The body of the generated le StockPricescs, containing the following code, which mentions StockPrices as the name of the class in the Name parameter of the WebServiceBinding attribute and in the Binding parameter of the SoapDocumentMethod attribute

Now imagine that you want to change the name of the web service Instead of StockPrices, you d prefer to call it StockValues Working in a modern coding environment, this should be a simple refactoring operation, such as the ones available from the Refactor menu in the code editor But unfortunately, opening the StockPricescs le and using the Refactor menu will not have the desired effect, because many of the occurrences of the name StockPrices are not in code However, changing the name from StockPrices to StockValues on the Application Designer diagram does have the right effect All of the references within the StockPriceApplication project are updated immediately, including the lenames and all of the references in the list above At this point, the consumer endpoint on the InvestmentCalculator project is marked with a small warning symbol to indicate that it is referring to something that has changed; the web reference in the InvestmentCalculator project has been removed, and the appconfig le no longer contains any reference to StockPrices Selecting the Implement option from the context menu on the endpoint causes the web reference, appconfig, and SDM

les to refer to the new name By using the DSL, the operation of changing the name has been reduced from a time-consuming and error-prone combination of multiple manual edits to a simple two-step procedure carried out at the appropriate level of abstraction You may ask what happens if you change the name of StockPrices in just one of these generated artifacts Well, by doing that you have invalidated your solution In general, it is dif cult or impossible for a tool to solve all of the possible round-tripping conundrums that could be created if you allow complete freedom to edit any artifact at any time In this particular case, you are allowed to insert your own code into the body of the GetPrice() method, and that code will be preserved if the endpoint or operation name is changed in the model But if you manually change the name of the class or method itself in the code, you have effectively broken the relationship between the code and the model, and future changes will not be synchronized We return to the general problem of keeping models and artifacts synchronized in 8 We can summarize the qualities of the Application Designer, which are qualities that any well-designed DSL should possess, as follows: It is a sharply focused tool for a speci c task The model corresponds closely to the domain being modeled, and the transformations required to generate code and other artifacts are simple Because of these simple transformations, the round-tripping problem becomes tractable The artifacts associated with the language are all les and can be maintained in a source-control system, and the tool is engineered so that it works effectively in this environment The interactive user experience on a modern computer is rapid and intuitive The les manipulated by the tool are user-readable text les, using published formats based on XML
