A Case Study: Replacing the persistence layer of a Business Process Engine with JDO The JDO specification (JSR-12) was released from the Java Community Process in April 2002. Its goal is to provide transparent persistence to Java classes. David Jordan provides a concise introduction. Several books are becoming available that provide a more complete description of JDO3.

基于AT89C51SND1C的硬盘MP3 MP3的全称为MPEGⅠ/Ⅱaudio layer 3.便携式MP3播放器以大量可擦写的FLASH存储器或硬盘存储器为存储戒指,音频信号以文件的形式存在存储介质中,在播放时,MP3播放器对MP3文件进行压缩和解码,并对音效进行设置,最后通过音频借口产生音频信号.

应用层组播(application-layer multicast,简称ALM)是网络层组播的重要补充.但与网络层组播不同的是,应用层组播结构的组成节点是具有独立利益和决策的主机用户.自私的主机用户为了提高自身利益,可能不严格遵守应用层组播协议的规定,从而对组播会话的整体性能带来影响.为了设计可信任的、鲁棒的应用层组播协议,对应用层组播的用户自私性进行研究是必要的.综述了这一领域的研究进展,并按照应用层组播协议的工作阶段把这些研究分为3类,即控制结构维护阶段的自私性研究、节点信息收集阶段的自私性研究以及数据结构构造阶段的自私性研究.

The Radio Interface Layer is the name for an interface that was developed especially for the Pocket PC Phone Edition. It is meant to abstract the interface with a phone/modem device. To achieve this it is closely modelled after the GSM AT command interface. Unfortunately the API was not published officially by Microsoft. Instead more high level API s were published that should be sufficient for developers. Again, unfortunately they are not sufficient. For example the API for receiving notification of incoming SMS messages is arranged for exclusively for one application per type of SMS. Apparently this will be improved upon in Pocket PC 2003. Another area is the availablity of a true AT command modem interface to interact with the GSM modem directly, which is also absent.
