Software Factory significantly increase the level of automation in application development at medium to large companies, applying the time tested pattern of using visual languages to enable rapid assembly and configuration framework based on other components.Unlike approach Model Driven Development (MDD), such as Model Driven Architecture (MDA) from the Object Management Group (OMG), Software Factories do not use the Unified Modeling Language (UML), a general purpose modeling language designed for models used as documentation. As global demand for software exceeds the capacity of this pool of labor, software development methods which will now be replaced by automated methods, meaning cheaper, faster, and more reliable application development. With two chapters on Domain Specific development (DSL) Language by contributors Steve Cook and Stuart Kent, they take a look in depth the challenges facing developers today using the methods and practices, and an important innovation that can help with challenges, such as Pattern Automation, Generative Programming , Software Product Lines, Aspect Oriented Programming (AOP), Component Based Development (CBD), Service Oriented Architecture (SOA), Service Orchestration and Web Service Integration. They then propose methods of Software Factory, which has the potential to significantly change software development practice, by reducing the cost of building reusable assets, such as patterns, languages, frameworks and tools, for a particular problem domain, and then apply it to accelerate assembly applications in that domain.
