Abstract: A system for transmitting information about securities comprising: a relational database and an analysis processor. The relational database is used to store a relational table that contains a plurality of relations concerning users of securities. When the analysis processor receives information about securities, the analysis processor determines a plurality of users who match the information about securities according to the relational table, and then transmits the information about securities to the plurality of users. When the system is transmitting information about securities, relational tables are established in order to reduce search loops that are required for determining the users, thus speeding up operations of the system and reducing system loads.

Abstract: A method for processing securities data comprises: analyzing a plurality of fields of a plurality of securities data in order to respectively conclude the statistic distribution summary of the values of each field of each securities data; defining a grouping and encoding process for the fields according to the distribution summary, and unifying the grouping and encoding processes for all fields into an encoding rule; and encoding the other securities data according to the encoding rule. The encoding rule can greatly reduce the amount of data and it comprises: classifying and rearranging number according to the codes of securities data in order to reduce the size of the transmission serial codes; indicating the relative price for the price of the securities data; indicating the relative time difference for the securities data which have any trading records in the previous one minute; and offering suitable field width and encoding process according to the size of each securities data to indicate its amount.
