Sitecore’s Digital Marketing System (DMS) – part of the Sitecore Customer Engagement Platform (CEP) – enables marketers to create targeted and optimized campaigns with minimal effort.
When a user visits your site for the first time, the Sitecore DMS will create a brand new Visitor record in the analytics database, and link this to a new Visit record. This visit record will be updated for the duration of that session with relevant information, such as pages visited, profiles triggered etc. Sitecore will also place two cookies onto the clients computer, one for the session, and a global cookie that will help Sitecore identify the visitor between sessions. These cookies are called SC_ANALYTICS_SESSION_COOKIE, and SC_ANALYTICS_GLOBAL_COOKIE respectively.
