Abstract

The advantages of object-oriented programming systems are well known. However, in general, they do not support long-lived objects, nor do they allow concurrent sharing or dynamic re-use of language defined objects. Persistent object systems address some of these shortfalls. In this paper we present a design and implementation of a persistent object system that uses memory-mapping to directly map objects from the persistent store into the address space of user programs. Memory mapping makes the management and manipulation of persistent objects simpler. In particular, complex object structures can be executed (shared) concurrently on behalf of separate applications. A simple language extension has been designed and added to C++ to make the programming of persistence, sharing, synchronization and consistency control expressible. With efficient run-time support for persistent pointer resolution and consistency maintenance, this approach can provide much finer-grain execution concurrentcy and sharing, easier object navigation, simpler programability and possibly better performance, than object-oriented database systems.<>

用于内存映射持久对象系统的并发编程环境

面向对象编程系统的优点是众所周知的。然而，一般来说，它们不支持长期对象，也不允许并发共享或动态重用语言定义的对象。持久对象系统解决了其中的一些不足。在本文中，我们提出了一个持久对象系统的设计和实现，该系统使用内存映射直接将对象从持久存储映射到用户程序的地址空间。内存映射使得持久化对象的管理和操作更加简单。特别是，复杂的对象结构可以代表不同的应用程序并发地执行(共享)。设计了一个简单的语言扩展，并将其添加到c++中，使持久化、共享、同步和一致性控制的编程具有可表达性。通过对持久指针解析和一致性维护的有效运行时支持，这种方法可以提供更细粒度的执行并发和共享、更容易的对象导航、更简单的可编程性以及比面向对象数据库系统更好的性能。
