<p>In a computing system, wherein applications access databases to obtain data and the databases are updated from time to time and the applications require consistent data from the databases even while an update is occurring, a first database (12A); a second database (12B), wherein the first database and second database are substantive copies of each other outside of an update period; a control manager (18) indicates to an update router (16) and a query router (14) which of the databases is the live database and which is the load database. The query router (14) routes queries from applications (10) to the live database.</p> |
