A method, apparatus, and/or computer program product manages sessions of different websites. Respective session identifiers of a plurality of websites are recorded, where each of the respective session identifiers of the plurality of websites identifies a session established in response to a page open operation for a respective website, and where pages of the plurality of websites are integrated into one page on one website. An operation request for a page of a first website of the plurality of websites is received. In response to receiving the operation request, a session synchronization request message that requests that a session of the first website be synchronized with sessions of the plurality of websites is generated and transmitted from the first website to other websites from the plurality of websites.

Method and apparatus for managing sessions of different websites

Managing database indexes includes creating a main index and creating at least one service index that is configured for recording a change to a node to be updated in the main index. Managing database indexes also includes detecting whether an operation that involves the main index and is performed on the database appears in the database, and maintaining the main index using at least one service index in response to the operation that involves the main index and is performed on the database, appearing in the database. The maintaining is performed based on changes to a node to be updated in the main index that are recorded in the at least one service node.

Database index management

The present invention relates to the technical field of data or file synchronization. In particular, the present invention relates to a method and system for data synchronization using character string matching. Provided are a method, computer program product, and system for data synchronization between a source node and target node. An old copy and a new copy of data to be synchronized is received. A block map is generated according to the difference determined using character string matching between the old copy and the new copy. The block map, which includes the position information of unchanged blocks and the position information and contents of changed blocks, is transmitted to a target node.
