Re: Software patent?
I agree with you, the implementation details and used terminology is
different but idea seems on surface very similar. Actual differences
must be on claims section. There are other similar CDC (Change Data
That is pretty funny. The flow chart is exactly the same as FlexCDC
which predates this. FlexCDC reads binary logs events, processes
them, writes them into another log, and then makes them available for
application to another database or for aggregate tables in the same
database, which is by definition a heterogeneous data source.
And FlexCDC is of course based on similar technology in DB2 and
Oracle. Oracle captures changes via logminer or streams, and DB2 has
a log capture utility that was used as the prototype for the algorithm
that Flexviews is based on.
Also, I have a talk called "realtime event capture ..." at the PLMCE
conference that talks about using FlexCDC to capture events and
propagate them to other systems.
This is also how Continuent works too.
