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.

應(yīng)用層組播(application-layer multicast,簡稱ALM)是網(wǎng)絡(luò)層組播的重要補(bǔ)充.但與網(wǎng)絡(luò)層組播不同的是,應(yīng)用層組播結(jié)構(gòu)的組成節(jié)點(diǎn)是具有獨(dú)立利益和決策的主機(jī)用戶.自私的主機(jī)用戶為了提高自身利益,可能不嚴(yán)格遵守應(yīng)用層組播協(xié)議的規(guī)定,從而對(duì)組播會(huì)話的整體性能帶來影響.為了設(shè)計(jì)可信任的、魯棒的應(yīng)用層組播協(xié)議,對(duì)應(yīng)用層組播的用戶自私性進(jìn)行研究是必要的.綜述了這一領(lǐng)域的研究進(jìn)展,并按照應(yīng)用層組播協(xié)議的工作階段把這些研究分為3類,即控制結(jié)構(gòu)維護(hù)階段的自私性研究、節(jié)點(diǎn)信息收集階段的自私性研究以及數(shù)據(jù)結(jié)構(gòu)構(gòu)造階段的自私性研究.

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.
