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. 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 database connections. Each replicate article within in a subscription subscribes to a primary article in the publication to which that subscription refers.
