pure::variants in a nutshell(转 www.software-acumen.com)pure::variants - variant Configuration Management。Furthermore,since you have now explicitly captured what is common and what differsbetween variants, it becomes possible to perform variant management inother parts of the software life cycle such as Requirements Management, Quality Assurance, Defect Tracking, Documentation etc.

在下面的代码中，先定义了一个带有内部函数声明的外部函数，然后调用外部函数：/* 创建全局变量 - y - 它引用一个对象：- */var y = {x:5}; // 带有一个属性 - x - 的对象直接量function exampleFuncWith(){ var z; /* 将全局对象 - y - 引用的对象添加到作用域链的前端：- */ with(y){ /* 对函数表达式求值，以创建函数对象并将该函数对象的引用指定给局部变量 - z - :- */ z = function(){ ...// 内部函数表达式中的代码; } }

Func<int, int> factorial = null;Parameter(typeof(Expression<SelfApplicableExpr<Expression<Func<Expression<Func<Expression<Func<int, int>>,Expression<Func<int, int>>>>,Expression<Func<int, int>>>>>>),"y");GetMethod( "Compile" ),new Expression[ ] { }),new Expression[ ] { y }),typeof(Expression<Func<Expression<Func<Expression<Func<int, int>>,Expression<Func<int, int>>>>,Expression<Func<int, int>>>>).

商业图表中的颜色运用，其重要性不言而喻，我们非设计专业人士，对色彩往往不是很有把握，色彩方面的教材看起来也不得要领，做出的图表用色上常常花哨或者脏乱，难以达到专业的效果。在《杂志级图表方法第一步：突破Excel的默认颜色》中已经提到，从商业杂志上的图表借鉴配色，则不失为一种非常保险和方便的办法。早年的商业周刊上的图表，几乎都使用这个颜色组合，基本成为商业周刊图表的招牌标志了，应该是来源于其VI系统。

The modeling world -Models in the Application Lifecycle I often use these images [below] to organize the discussion that is going on in the modeling-world according to UML vs DSL. It gives some direction where we are talking about when discussing ''Modeling in the Application Lifecycle''.Domain Specific Languages [business, vertical, external] Model Assisted Development (MAD)

Ad Hoc Reporting with a Domain ModelKickoff question: Luke Hohmann, Luke Hohmann Consulting.On the other hand business execs want / crave / require &quot;ad-hoc&quot; reporting, with the degree of &quot;ad-hoc-ness&quot; varying from simple reports to data warehouses.One is consider just how &quot;ad hoc&quot; ad hoc really is.Another perspective is to consider how timely the data subject to ad ho

Domain-Driven / Model-Drivenby Eric EvansFebruary 4, 2004.And so domain-driven design leads inevitably to modeling because modeling is the way we grapple with understanding complex domains.For in model-driven design, the design is not only based on the model, a model is also chosen to suit design and implementation considerations.

So a language workbench is one way to do language oriented programming.Internal DSLs are often called ''embedded DSLs'' but I''ve avoided the ''embedded'' term because it gets confused with embedded languages in applications (such as VBA embedded into Word which if anything is an external DSL.) However you''ll probably come across the embedded term if you look around at more writing on DSLs.

In general we build an editor for each concept in our model. (It''s not quite one for one, but that''s a good place to start thinking.)To define the editor for plans we use the editor for editors (it''s getting hard to avoid the metacircularity here.) Editors are defined as a hierarchy of cells.The delimiters in the plan editor (such as [/ and [&gt;) are also constants defined in the editor for ed

The tool persists the abstract representation in a storage representation, but this is entirely separated from any of the editable representations that it projects.The abstract representation may be edited through multiple projections, each projection can show a limited amount of the total information which isn''t tied to the actual structure of the abstract representation.

In this approach the parser can generate an AST and the code generator can work directly off the AST. This is a reasonable approach providing the AST is a good model of the underlying semantics and you don''t mind coupling the code generation logic to the AST. If those aren''t the case you may well it''s simpler to transform the AST to a Semantic Model and do a simpler code generation from that.

The key deliverables for a Software Factory are the Software Factory Schema and the Software Factory Template as shown in Figure 5.Once more I would like to emphasize, that developing a Software Factory, as any other software development, should be done in an iterative way and the Software Factory Schema and Software Factory Template will be evolved over many development iterations.
