How Data is Replicated 

 How Data is Replicated

Replication uses the Look-Up Tables (apart from in the case of simple intelligent or simple unfiltered (single bulk) replication objects) to determine the sites (laptops, local databases) that are responsible for the Replication Object, fills the recipient list and releases the object for further processing. For replication objects of type simple intelligent or simple unfiltered the recipient list is constantly updated.

For replication objects of type intelligent or unfiltered (bulk), the replication checks if the replication object needs to be transferred to the Realignment and if necessary places it in the corresponding queue.

Example

First a publication is created, for example “postal code area customer”. This is the basis for distribution of the replication object “Customer” according to postal codes.

Then Subscriptions are defined for the publication “postal code area customer”. Various sites (for example A001 and A002) can now be subscribed here for certain criteria values (for example site A001 for the postal code area 30000-40000 and site A002 for the area 40000-50000).
