In MobiLink, a synchronization subscription links a particular MobiLink user with a publication. It can also contain other information needed for synchronization. For example, you can specify the address of the MobiLink server and any options for a synchronization subscription. Values for a specific synchronization subscription override those set for MobiLink users. Synchronization subscriptions are required only in MobiLink SQL Anywhere remote databases. Server logic is implemented through synchronization scripts, stored in the MobiLink system tables in the consolidated database.

In SQL Remote, data is organized into publications for replication. To receive SQL Remote messages, a subscription must be created for a user ID with REMOTE permissions. Publications and subscriptions are two-way relationships in SQL Remote. If you create a subscription for a remote user to a publication on a consolidated database, you should also create a subscription for the consolidated database on the remote database. The Extraction utility (dbxtract) carries this out automatically.
