+--- **AceDB-3.0** manages the SavedVariables of your addon.
+-- It offers profile management, smart defaults and namespaces for modules.\\
+-- Data can be saved in different data-types, depending on its intended usage.
+-- The most common data-type is the `profile` type, which allows the user to choose
+-- the active profile, and manage the profiles of all of his characters.\\
+-- The following data types are available:
+-- * **char** Character-specific data. Every character has its own database.
+-- * **realm** Realm-specific data. All of the players characters on the same realm share this database.
+-- * **class** Class-specific data. All of the players characters of the same class share this database.
+-- * **race** Race-specific data. All of the players characters of the same race share this database.
+-- * **faction** Faction-specific data. All of the players characters of the same faction share this database.
+-- * **factionrealm** Faction and realm specific data. All of the players characters on the same realm and of the same faction share this database.
+-- * **global** Global Data. All characters on the same account share this database.
+-- * **profile** Profile-specific data. All characters using the same profile share this database. The user can control which profile should be used.
+--
+-- Creating a new Database using the `:New` function will return a new DBObject. A database will inherit all functions
+-- of the DBObjectLib listed here. \\
+-- If you create a new namespaced child-database (`:RegisterNamespace`), you'll get a DBObject as well, but note
+-- that the child-databases cannot individually change their profile, and are linked to their parents profile - and because of that,
+-- the profile related APIs are not available. Only `:RegisterDefaults` and `:ResetProfile` are available on child-databases.
+--
+-- For more details on how to use AceDB-3.0, see the [[AceDB-3.0 Tutorial]].
+--
+-- You may also be interested in [[libdualspec-1-0|LibDualSpec-1.0]] to do profile switching automatically when switching specs.
