    • A method of synchronizing at least one database including first data records of a portable electronic device with at least one other database including second data records. The method includes receiving information representative of the first data records and comparing the information representative of the first data records with information representative of the second data records to determine if changes made to either the first data records or the second data records are not reflected in the other of the first and second data records. If changes made to the second data records are not reflected in the first data records, only partial content of ones of changed second data records is transmitted to the portable electronic device. The partial content includes key fields of data sufficient to uniquely identify the ones of the changed second data records in which the key fields of data are contained. After transmitting only partial content of the ones of changed second data records to the portable electronic device, full content of the ones of changed second data records for which only partial content has been transmitted, is transmitted until either full content of each of the ones of the changed second data records is transmitted or a low memory condition is determined at the portable electronic device.
    • 一种将包括便携式电子设备的第一数据记录的至少一个数据库与包括第二数据记录在内的至少一个其他数据库同步的方法。 该方法包括:接收表示第一数据记录的信息,并将表示第一数据记录的信息与表示第二数据记录的信息进行比较,以确定对第一数据记录或第二数据记录进行的改变是否不反映在 其他第一和第二个数据记录。 如果对第二数据记录的改变没有反映在第一数据记录中,则仅将改变的第二数据记录的部分内容传送到便携式电子设备。 部分内容包括足以唯一地标识包含数据的关键字段的改变的第二数据记录中的数据的关键字段。 只有将改变后的第2数据记录的部分内容发送到便携式电子设备之后,发送只有部分内容被发送的改变后的第2数据记录的全部内容,直到全部内容 发送改变的第二数据记录或在便携式电子设备处确定低存储器条件。

    • A method for memory management in an electronic device includes receiving partial content data records at the electronic device, storing the partial content data records in a memory of the electronic device, receiving a full content data record corresponding to one of the partial content data records, determining whether or not sufficient memory is available in the memory of the electronic device to store the full content data record and, if so, writing the full content data record over the corresponding partial content data record stored in the memory; and repeating the receiving and determining until either: full content data records corresponding to each of the partial content data records are received; or a low memory condition is determined in the memory. The partial content data records include key fields of data sufficient for uniquely identifying corresponding full content data records at a second electronic device.
    • 一种用于电子设备中的存储器管理的方法包括在电子设备处接收部分内容数据记录,将部分内容数据记录存储在电子设备的存储器中,接收对应于部分内容数据记录之一的完整内容数据记录, 确定在电子设备的存储器中是否有足够的存储器可用于存储全部内容数据记录,并且如果是,则将全部内容数据记录写入存储在存储器中的相应部分内容数据记录; 并重复接收和确定,直到接收到与每个部分内容数据记录相对应的全部内容数据记录; 或在存储器中确定低存储器条件。 部分内容数据记录包括足以在第二电子设备上唯一地标识相应的全部内容数据记录的数据的关键字段。
