This article briefly discussed various aspects of DB2 and Informix, such as editions, architecture, process and memory model, databases and storage models.
本文简要讨论了DB2和Informix的不同方面，例如编辑、体系结构、进程、内存模型、数据库和存储模型。
It was a TRS-80 model 1 with 4kb of memory and cassette tape mass storage, which I later upgraded to an Exatron stringy floppy.
那是一台TRS- 80机型1，它具有4kb内存和大容量存储磁带，之后我将其升级为Exatron软盘。
Message cursors are part of a new memory model that allows messages to be paged in from storage when space is available (using Store cursors for persistent messages).
消息指针(MessageCursors)是新的内存模型的一部分，当有可用的空间时(对持久化的消息使用存储指针)，它可以在存储地对消息进行分页。
In the model, the short-period memory capacity restricting theory is used to save a large mount of system storage space so as to provide a good condition for system distributed expansion;
在该模型中，应用短时记忆容量限制理论来节省系统大量的存储空间，为系统的分布式扩展提供了良好的条件；
