项目摘要

Models and components are two well-accepted concepts in modern software engineering to support the development, adaptation, and evolution of software systems and to manage the complexity of software systems. Although in both, in model-based and in model-driven software development, models and code are managed simultaneously, these appraoches often lead to inconsistencies between the two levels. Furthermore, the concept of components is used primarily at the code level, such that this structuring element is missing at the model level.In this research project, a novel model integrating software development approach (Model-Integrating Development (MID)) shall be analyzed, which is based on a mainly non-redundant combination and integration of models and code in the form of model-integrating components (MoCos). In this way, important knowledge of the software is explicitly preserved and maintained at software evolution time. Here, the model part of a MoCo supports flexibility and comprehensibility of the component while the code part is responsible for the efficient realization, the use of standard software, and the connection to middleware. Thus, models may also be manipulated at runtime to support self-adaptation.In MoCos, models and code are both first class entities. The boundary between models and code in a MoCo shall remain movable in order to react to changing requirements or to add a desired functionality for self-adaptation in a flexible manner. For this purpose, code shall be generated from parts of the models (freezing), and parts of the code shall be transferable into models by reverse engineering (melting). Components of existing component models (e.g., OSGi components) shall also be transferable into MoCos, which enables the introduction of self-adaptation at the component level.For the exploration of this novel component realization concept, a number of basic research questions have to be analyzed in order to develop an extensive concept for MoCos. Two case studies from the fields of service-oriented architectures (SOAs) and (dynamic) software product lines (SPLs) shall demonstrate the feasibility of our approach.

模型和组件是现代软件工程中的两个良好接受的概念，可支持软件系统的开发，适应和演变并管理软件系统的复杂性。尽管在基于模型和模型驱动的软件开发中，模型和代码是同时管理的，但这些评估通常会导致两个级别之间的不一致之处。此外，组件的概念主要用于代码级别，因此在模型级别上缺少了该结构元素。在该研究项目中，应分析一个新型模型整合软件开发方法（模型整合开发（MID））这是基于模型和代码的主要非冗余组合和模型集成组件（MOCOS）形式的集成。通过这种方式，在软件演化时，明确保留并维护了该软件的重要知识。在这里，MOCO的模型部分支持组件的灵活性和可理解性，而代码部分负责有效实现，使用标准软件以及与中间件的连接。因此，在运行时也可以操纵模型以支持自我适应。在MOCOS，模型和代码都是一流的实体。 MOCO中模型和代码之间的边界应保持可移动，以应对不断变化的要求或以灵活的方式添加所需的功能以进行自适应。为此，应从模型的一部分（冻结）生成代码，并且代码的一部分应通过反向工程（熔化）转移到模型中。现有组件模型（例如OSGI组件）的组件也应转移到Mocos中，该组件能够在组件级别引入自适应。对于探索这一新型组件实现概念，必须进行许多基础研究问题进行分析是为了开发Mocos广泛的概念。来自以服务为导向的体系结构（SOA）和（动态）软件产品线（SPL）领域的两项案例研究应证明我们方法的可行性。
