Designing Lines Product Software with Designing Software Product Lines with UML: From Use Cases to Pattern-Based Software Architectures 第一部分
Long a standard practice in traditional manufacturing, the concept of product lines is quickly earning recognition in the software industry. A software product line is a family of systems that shares a common set of core technical assets with preplanned extensions and variations to address the needs of specific customers or market segments. When skillfully implemented, a product line strategy can yield enormous gains in productivity, quality, and time-to-market. Studies indicate that if three or more systems with a degree of common functionality are to be developed, a product-line approach is significantly more cost-effective.

To model and design families of systems, the analysis and design concepts for single product systems need to be extended to support product lines. Designing Software Product Lines with UML shows how to employ the latest version of the industry-standard Unified Modeling Language (UML 2.0) to reuse software requirements and architectures rather than starting the development of each new system from scratch. Through real-world case studies, the book illustrates the fundamental concepts and technologies used in the design and implementation of software product lines.

This book describes a new UML-based software design method for product lines called PLUS (Product Line UML-based Software engineering). PLUS provides a set of concepts and techniques to extend UML-based design methods and processes for single systems in a new dimension to address software product lines. Using PLUS, the objective is to explicitly model the commonality and variability in a software product line.

Hassan Gomaa explores how each of the UML modeling views—use case, static, state machine, and interaction modeling—can be extended to address software product families. He also discusses how software architectural patterns can be used to develop a reusable component-based architecture for a product line and how to express this architecture as a UML platform-independent model that can then be mapped to a platform-specific model.

Key topics include:

Software product line engineering process, which extends the Unified Development Software Process to address software product lines

Use case modeling, including modeling the common and variable functionality of a product line

Incorporating feature modeling into UML for modeling common, optional, and alternative product line features

Static modeling, including modeling the boundary of the product line and information-intensive entity classes

Dynamic modeling, including using interaction modeling to address use-case variability

State machines for modeling state-dependent variability

Modeling class variability using inheritance and parameterization

Software architectural patterns for product lines

Component-based distributed design using the new UML 2.0 capability for modeling components, connectors, ports, and provided and required interfaces

Detailed case studies giving a step-by-step solution to real-world product line problems

Designing Software Product Lines with UML is an invaluable resource for all designers and developers in this growing field. The information, technology, and case studies presented here show how to harness the promise of software product lines and the practicality of the UML to take software design, quality, and efficiency to the next level.
