Architecture Specification

AbstractAs software architecture is a main driver for the software quality, source code is often accompanied by software architecture specifications. When the implementation is changed, the architecture specification is often not updated along with the code, which introduces inconsistencies between these artifacts. Such inconsistencies imply a risk of misunderstandings and errors during the development, maintenance, and evolution, causing serious degradation over the lifetime of the system. In this chapter we present the Explicitly Integrated Architecture approach and its tool Codeling, which remove the necessity for a separate representation of software architecture by integrating software architecture information with the program code. By using our approach, the specification can be extracted from the source code and changes in the specification can be propagated to the code. The integration of architecture information with the code leaves no room for inconsistencies between the artifacts and creates links between artifacts. We evaluate the approach and tool in a use case with real software in development and with a benchmark software, accompanied by a performance evaluation.

Architecture Specification

Service-oriented software systems (SOSS) are becoming the leading paradigm of software engineering. The crucial elements of the requirements specification of SOSSs are discussed as well as the relation between the requirements specification and the architecture of SOSS. It is preferable to understand service orientation not to be limited to Web services and Internet only. It is shown that there are several variants of SOSS having different application domains, different user properties, different development processes, and different software engineering properties. The conditions implying advantageous user properties of SOSS are presented. The conditions are user-oriented interfaces of services, the application of peer-to-peer philosophy, and the combination of different technologies of communication between services (seemingly the obsolete ones inclusive), and autonomy of the services. These conditions imply excellent software engineering properties of SOSSs as well. Service orientation promises to open the way to the software as a proper engineering product.

Architecture Specification

Model driven architecture (MDA) is an architecture specification of software development proposed by OMG in July 2001. MDA holds that the best way of software development is to enhance the level of abstraction of the system, isolate the design and implementation of the system, and separate the business conduct, so as to overcome the difficulties caused by the complexity of software. This paper presents the basic concept and core technology, and gives the software development process based on MDA.

Architecture Specification

Despite the growing importance of multimedia applications, we still know relatively little about how to specify, design, and maintain this class of complex applications in a systematic manner. The concept of software architecture has recently emerged as a way to improve our ability to effectively construct and maintain large-scale complex software systems. Under this new paradigm, software engineers are able to do evolutionary design of complex systems through architecture specification, design rationale capture, architecture validation and verification, and architecture transformation. Several architecture description languages (ADLs), such as Wright, Rapide, UniCon, ACME, etc. have been proposed to support the architecture development under this new software paradigm. Although current ADLs more or less support certain features of object-oriented design approach, few of them are purely based on object-oriented paradigm. In this paper, we present an architecture description language — OOADL (Object-Oriented Architecture Description Language) to facilitate the architecture specification of multimedia software systems. This language takes object-oriented paradigm as its backbone, and provides formal semantics for modeling architectures of software systems. It also aims at other goals such as, support for hierarchical refinement, support for reuse of architecture styles, support for analysis, and support for exception handling. We also introduce the default architecture style which brings the features of extensibility and re-usability into the language. Finally, we use OOADL to construct part of the architecture framework of a multimedia system to illustrate the usage and modeling capability of OOADL.
