Multi-index search device for acquiring e.g. stock market information, has database updated periodically by clock that synchronizes multi-indexed requests in database to display index lines issued from really simple syndication flow lines

摘要

The device has a database (Bn) updated periodically by a clock (H) that synchronizes a set of multi-indexed requests in the database for displaying index lines issued from really simple syndication (RSS) flow lines (f1-fn). The clock synchronizes an alarm to be triggered during the display of an index present in the multi-indexed request. The clock period is controlled by the arrival of new flow lines in the database.
