Embodiment Construction

[0051] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0052] The basic idea of ​​the search method in the present invention is: in the changelog of data synchronization equipment (such as terminals such as mobile phones or PDAs (Personal Digital Assistant, handheld computers), servers or any other equipment that can realize data synchronization), each modification record item Arranged according to the numerical order of the entity identifiers contained in each item;

[0053] In the data synchronization device, when data update occurs on an entity in the database on it, the element search algorithm in the ordered sequence is used to search the above-mentioned changelog to see if there is a modification record item containing the entity identifier.

[0054] Correspondingly, as figure 1 As shown, the basic concept of the update method is: after completing the search according to the above s...

Abstract

The invention relates to a searching, a updating and a synchronic method of amendment record items in a change log and a data synchronic device. The searching method comprises the following steps: each amendment record item in a change log of a data synchronic device is lined up according to the numeric value of an entity identifier contained in each item; when the entity data in a database of the data synchronic device is updated, the amendment record item containing the entity identifier is searched in the change log through a searching calculation of the elements in an ordered series. The updating method comprises the following steps: if relevant amendment record item is judged to exist through the above searching method, the original updating information in the amendment record item is changed to the present updating information according to a superposition strategy; otherwise, the amendment record item corresponding to the present updating is added to the change log, and the amendment record items in the change log after the addition are still lined up according to the numeric value of the entity identifier contained in each item. The method can greatly improve the searching speed of the amendment record items.

Description

technical field [0001] The present invention relates to personal information management (Personal Information Manager, PIM) (data synchronization) services of terminals in the field of communication, in particular to a method for searching, updating and synchronizing modified record items and a data synchronizing device. Background technique [0002] The management of personal information, schedule information, email information, etc. of terminals such as mobile phones and PDAs (Personal Digital Assistants) has become an important part of terminal information management. How to safely and effectively back up data to the network server, and how to conveniently restore the backup data to the terminal when the terminal is replaced or the terminal data changes has become the subject of data synchronization. The SyncML protocol can realize the data synchronization between the terminal and the server such as the network, and finally make the data on the terminal and the server con...
