This is a book about patterns for resource management in software systems The patterns provide solutions for problems that are typically encountered by software architects and developers when trying to provide an effective and efficient means of managing resources in a software system Efficient management of resources is critical in the execution of any kind of software From embedded software in a mobile device to software in a large enterprise server it is important that resources such as memory threading files or network connections are managed efficiently to allow the systems to function properly and effectively
The first volume of the Pattern Oriented Software Architecture POSA series [POSA1] introduced a broad spectrum of general purpose patterns in software design and architecture The second volume of the series [POSA2] narrowed the focus to fundamental patterns for building sophisticated concurrent and networked software systems and applications This volume uses patterns to present techniques for implementing effective resource management in a system
The patterns in this book are covered in detail and make use of several examples As with the previous POSA volumes the book provides directions to the readers on how to implement the patterns presented Additionally the volume presents a thorough introduction to resource management and two case studies in which the patterns are applied to two different domains The patterns presented are independent of any implementation technique such as NET Java or C++ even though the examples are given in Java and C++ The patterns are grouped by different areas of resource management and hence address the complete lifecycle of resources: resource acquisition resource lifecycle and resource release
The patterns in the book provide an extensive coverage of the sphere of resource management We began documenting these patterns several years ago based on our experiences of building many different software systems Most of the patterns have been presented or workshopped at leading conferences However what we felt was missing was an effort to pull the patterns together in the form of a pattern language and present it in such a way that the pattern language can be applied to multiple domains
The scope of resource management is vast The challenges that are faced by system designers and developers dealing with the management of resources are constantly changing as new technologies emerge We anticipate that additional patterns in resource management will be discovered and documented with time The Concluding Remarks chapter of this book talks about what lies ahead in the effort to evolve the resource management pattern language ">This is a book about patterns for resource management in software systems The patterns provide solutions for problems that are typically encountered by software architects and developers when trying to provide an effective and efficient means of managing resources in a software system Efficient ma [更多]
