Data management method for stock exchange field, involves comparing group identifiers with updated group identifiers, and transmitting content of group for which data identifier is different from updated group identifier to client station

摘要

The method involves regrouping data of a dataset (Dt) into data groups (GR1-GRN) based on data identifiers (AA, FZ, TA, ZZ). The data and group identifiers of each group are transmitted to a client station (3). An updating dataset is received from the dataset (Dt) at a broadcasting server (2) and whose data is regrouped in the groups based on the data identifiers. The group identifiers are compared with updated group identifiers by the server. Content of the group for which the data identifier is different from the updated group identifier is transmitted by the server to the station.
