 Before you read on, it may be helpful to get some information about the solution of ``horizontal'' data storage into the tables and cross referencing.
-Some of the tables are just using 4 attributes:
+Some of the tables are just using 5 attributes:
 \begin{enumerate}
-\item UID: This countains an unique ID for the complete entry.
-\item ID: This defines a number to seperate the rows of an entry.
+\item UID: This countains an unique ID for the complete entry. An entry may consist of multiple
+rows, seperated by ID.
+\item ID: This defines a number to seperate the rows of an entry. UID + ID must be unique for every entry.
 \item Type: Describes the type of this entry.
-\item Value: And the data which was described by ``Type'' is stored here.
+\item Priority: For instance: Your default email-address will get the priority 1 and the other 2.. . 0 means ``not defined''.
+\item Value: The data which was described by ``Type'' is stored here.
 \end{enumerate}
 
-These kinds of tables are very flexible in what they may contain, due to the fact that the ``Type'' may be without any constraint. Therefore it is perfectly for storing personal information, which may change in the future, or should be increased. The other advantage is the fact that these tables are automatically convertable into XML:
-The ``Type'' has just to be converted into an ``attribute'' in a XML-tag. Thats all, and that will work for all future Types !

-Thus, it is possible to crossreference i.e. a Child (Item1 = ``Child'') in the Table PERSONAL\_DATA (TID1 = 0) with an entry in the Table ADDRESSBOOK (TID= 1, Item2 = ````) which stores the data of that child.\\
-
-\noindent
-Using ``Item'' to select which element should be referenced (instead using the ID which may only exist in our table) should guarantee that this reference may survive conversions between different formats. I.e.: For converting our Database into a XML-File, the Item should be converted directly into a attribute-name which is placed into a tag. Therefore the cross reference will stay correct!
