Hi All, Some more information on the subject is below. Maybe we can try to use "M" language (see below) in our Northwind.NET project to define Northwind Business Model? - just to have a formal specification built using emerging standard(?) and then implemented in our custom codind whatever way we will decide to do that IOW I'm just thinking to use "M" language currently in written form, but not use any beta/CTP MS Tools as we do not have time for that... "M" http://msdn.microsoft.com/en-us/library/dd129519(VS.85).aspx <<< The Microsoft code name "M" language is a declarative language for working with data and building domain models. "M" lets users write down how they want to structure and query their data using a textual syntax that is convenient to both author and reader. "M" does not mandate how data is stored or accessed, nor does it mandate a specific implementation technology. Rather, "M" is designed to allow users to write down what they want from their data without having to specify how those requirements are met by a specific technology or platform. >>> Textual Domain Specific Languages for Developers - Part 1 http://msdn.microsoft.com/en-us/library/dd441702.aspx <<< Oslo makes building these DSLs easier, but how do these little languages affect the everyday work of developers? Instead of replacing the work of developers, DSL present the opportunity to work on the interesting part of the problem space, not just the rote code that many developers are forced to hand-code or generate from metadata. Because Oslo empowers developers to use metadata driven from DSLs anywhere in their applications, developers can be more productive and create agile, scalable systems that are a better representation of what the customer actually wants; not what the developer thought the customer wanted. >>> Workflows, Services, and Models http://msdn.microsoft.com/en-us/library/dd200919.aspx The "Oslo" Modeling Language Specification http://msdn.microsoft.com/en-us/library/dd285282.aspx Thank you. -- Shamil -----Original Message----- From: Salakhetdinov Shamil <mcp2004 at mail.ru> To: dba-VB <dba-vb at databaseadvisors.com> Date: Sun, 26 Apr 2009 13:46:33 +0400 Subject: [dba-VB] The "Oslo" Modeling Platform - to use or not? > Hi All, > > I have just occasionally get at the site of "The "Oslo" Modeling Platform" (sorry for my ignorance): > > http://msdn.microsoft.com/ru-ru/library/dd129514(en-us).aspx > > (and I have heard/seen presentations on MS works on Domain Specific Language (DSL) somewhere back to year 2004 when they were announcing this DSL support will be soon available in VS). > > Comparing to ADO.NET Entity Framework, which I tend to expect/hope will be finally (in the near future) a useful development tool, I doubt in "Oslo" platform broad applicability in real life business development as it's planned there: "If a data-driven application has enough detailed model information, applications can run without recourse to static compilation"... > > I can be wrong, but my gut feeling is that the truth of the "never ending battle" between imperative and declarative application development is somewhere in between and in my opinion "The "Oslo" Modeling Platform" targeting the edge/marginal side of the declarative development/programming, which will never come true... > > I can be wrong of course. Please write your opinion -- I'd feel especially happy if you can explain what are the reasons MS folks believe in the "Oslo" platform's bright future. Of course I realize the reasons to explain that could be of so high level nature that I will be unable to understand them... > > Recap: I'm feeling OK on "The "Oslo" platform" being a research project there at MS with some useful outputs, but I doubt it will ever be used as "platform" for real life business application.
