FIELD: information technology. ^ SUBSTANCE: changes in elements are tracked in accordance with a defined group of properties, and each group is tracked independent of the other. For example, one group may contain large data elements, for example inputs, while the other group may include highly changeable properties, such as an execution control flag feature. Rate of synchronisation between a client and a server is increased by synchronising only selected parts of the element which have changed without controlling change in each separate property within the element. Accordingly, if change has been made with respect to a small information property (for example, an execution control flag feature) in a relatively large email message, such a change will not initiate a large load on the client working in cache mode, and will also not require considerable storage space and processing in order to track each separate property. ^ EFFECT: high rate of synchronisation between a client and a server. ^ 20 cl, 6 dwg |
