Sandbox Services Data Model

A ChangeSummary encapsulates information related to a change made to a sandbox trackable entity. It stores the change details, as well as author, and state information. It is also aware of exception information related to problems that may have occurred during an attempted transition at the resource tier service. It is also aware of rejection messaging to display to the change author should the change be refused by an approval user.

A ChangeSummaryGroup serves as a grouping structure that contains multiple ChangeSummaries. User authored changes are always grouped together into a ChangeSummaryGroup at the time of promotion by the author. Approvers always review groups and can view details on the group to look at more granular details.

A ChangeDeploy represents one or more groups (and all the associated individual summaries) that are deployed at a moment in time. Deployment signifies the operation during which approved changes are applied to the production state of one or more sandboxable entities.

A Sandbox is a marker construct to identify changes conceptually. Sandboxes can signify a commonly used concept, like "default sandbox" or "hot fix sandbox". Sandboxes can also denote a more temporary concept, like "fall campaign". Changes by multiple users can be associated with a sandbox, and multiple sandboxes can be active at any time to serve different needs.
