Description:
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.
As the need for resource management is often discovered late in the software development lifecycle, and changing the system design at this late stage is difficult, it is important that such tasks are performed early in the lifecycle. Since systems belonging to different domains have different system constraints and requirements, a technique that works well in a particular system or configuration might not be so effective in another.
POSA 3 uses patterns to present techniques for implementing effective resource management in a system. The patterns are covered in detail, making use of several examples, and, as in previous POSA volumes, directions are given on how to implement the presented patterns. Additionally, the volume presents a thorough introduction into resource management, and two case studies where the patterns are applied to the domains of ad hoc networking and mobile radio networks. The patterns are grouped by different areas of resource management and hence address the complete lifecycle of resources: resource acquisition, coordination and release.

商品描述(中文翻譯)
描述:
資源的有效管理在任何類型的軟體執行中都是至關重要的。從行動裝置中的嵌入式軟體到大型企業伺服器中的軟體,資源(如記憶體、執行緒、檔案或網路連接)的有效管理對於系統的正常運作和有效性至關重要。
由於資源管理的需求通常在軟體開發生命週期的後期才被發現,而在這個晚期階段改變系統設計是困難的,因此在生命週期的早期執行這些任務是很重要的。由於不同領域的系統具有不同的系統限制和需求,因此在特定系統或配置中有效的技術在其他系統中可能不那麼有效。
《POSA 3》使用模式來呈現實現有效資源管理的技術。這些模式詳細介紹,並利用多個範例,與之前的《POSA》卷一樣,提供了如何實現所呈現模式的指導。此外,本卷還對資源管理進行了全面的介紹,並提供了兩個案例研究,展示這些模式在臨時網路和行動無線網路領域的應用。這些模式按不同的資源管理領域分組,因此涵蓋了資源的完整生命週期:資源獲取、協調和釋放。
