+/**
+ * Data access interface
+ *
+ * This interface specifies data access methods libomb needs. It should be
+ * implemented by libomb users. OMB_Datastore is libomb’s main interface to the
+ * application’s data. Objects corresponding to this interface are used in
+ * OMB_Service_Provider and OMB_Service_Consumer.
+ *
+ * Note that it’s implemented as a class since OAuthDataStore is as well a
+ * class, though only declaring methods.
+ *
+ * OMB_Datastore extends OAuthDataStore with two OAuth-related methods for token
+ * revoking and authorizing and all OMB-related methods.
+ * Refer to OAuth.php for a complete specification of OAuth-related methods.
+ *
+ * It is the user’s duty to signal and handle errors. libomb does not check
+ * return values nor handle exceptions. It is suggested to use exceptions.
+ * Note that lookup_token and getProfile return null if the requested object
+ * is not available. This is NOT an error and should not raise an exception.
+ * Same applies for lookup_nonce which returns a boolean value. These methods
+ * may nevertheless throw an exception, for example in case of a storage errors.
+ *
+ * Most of the parameters passed to these methods are unescaped and unverified
+ * user input. Therefore they should be handled with extra care to avoid
+ * security problems like SQL injections.
