Hi
You want to know difference about concepts or features in Talend?
The ability to capture only the changed source data and to move it from a source to a target system(s)
in real time is known as Change Data Capture (CDC).
In TIS, this feature is more powerful which support publish/subscribe principle. You can use it to mirror two databases.
The feature about SCD is shown in User Guide.
