Publications and subscriptions

Publications and subscriptions are always defined within the context of a database connection; therefore, each publication or subscription is associated with a specific database connection. Publications are defined in primary database connections; subscriptions are defined in replicate database connections. Each database connection can contain many publications or subscriptions.

Publications and subscriptions allow you to organize primary and replicate articles in a database. Before you can create an article, you must first create a publication or subscription to contain the article. Each publication or subscription can contain many articles.

Each subscription refers to (subscribes to) a specific publication. A publication can be subscribed to by any number of subscriptions, in any number of replicate databases. Each article in a subscription subscribes to an article in the publication to which that subscription refers.
