Embodiment Construction

[0036] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0037] The present invention is a document sharing method based on content difference comparison, figure 1 The specific implementation process of the present invention is shown:

[0038] For operating terminals that provide document sharing, the steps are as follows:

[0039] Step 1: Shared document initialization;

[0040] It is mainly to initialize the document that needs to be shared first, including opening the document, saving the document, and transferring the initial document to the browsing terminal through the document transfer protocol for sharing. In order to ensure that the initial state of each browsing terminal is consistent with the state of the operating terminal, a complete initial document needs to be distributed to each browsing terminal through the network for initialization, and the content of the initial document is used as the...

Abstract

The invention discloses a method for sharing a document based on content difference comparison, and the method comprises the following steps: initializing a shared document at network user terminals; waiting for document content change; comparing the difference of the changed document and the unchanged content; carrying out lossless compression and sharing on the difference comparison result; receiving an update package by a browse terminal user from an operating terminal; and decompressing the update package and combining with the current document. The method can not only guarantee the completeness and timeliness of online document sharing but also greatly reduce the network bandwidth resource consumption caused by document sharing.

Description

technical field [0001] The invention belongs to the technical field of databases, and in particular relates to a document sharing method based on content difference comparison. Background technique [0002] With the continuous popularization of the Internet and the continuous development of new technologies, automated office systems have largely eliminated many functions of traditional offices. Many enterprises have begun to use network technology and database technology to share and collaborate on various reports, speeches and other documents in daily work, realizing paperless office. In the ever-growing network applications, limited network bandwidth conditions are still a limiting condition for network applications. Document sharing is an application of massive data on the network, and its application effect is limited by the technology and network bandwidth conditions used. [0003] At present, there are mainly the following methods for document sharing technology: onli...
