Abstract
In order to perform relatively frequent, zero-downtime software updates, a bridge schema corresponding to an original schema of a database system may be generated. Within the bridge schema, a plurality of views corresponding to a plurality of database tables of an application executing on an application server may be generated. A connection from the application to the original schema may be changed to the bridge schema, to thereby continue executing the application using the plurality of views. When a change file defining update changes to at least one original database table of the plurality of database tables is received, content of the at least one original database table may be synchronized with a target table reflecting the update changes. Then, the connection may be changed back to the original database schema to continue executing the software application, using the plurality of database tables and including the target table.
