the XNF is restricted to the subtree determined by this context path.
But then the absolute XNF for [S.sub.1] cannot be achieved.
In this section we will discuss how to transform an ER (Entity-Relationship) schema [28] into XML schema in XML normal form (XNF).
Satisfaction of this condition is the prerequisite to obtain an XML schema in absolute XNF in the next step.
The DA algorithm [1] is applied to obtain the final XNF schema.
Now, using the Theorem 7.3 and DA, the transformation of ER into XNF is realized in the following two steps:
db [right arrow] supplier * partDese * supplier [right arrow] sid sname part * partDesc [right arrow] pid pname part [right arrow] pid did offer * offer [right arrow] oid price delivTime (3) Applying the above steps to the ER schema from Figure 12 gives the XML schema in XNF depicted in Figure 15 and its instance in Figure 16.
To define XNF we use the approach proposed in [24].
Figure 5 shows the pointer structure maintained by an example IMS attachment that would be useful for evaluating our XNF example, in which the Departments table is the parent table and the Employees table is the child table.
Alert solves this dilemma by allowing a method on any application-specific object (including a view or XNF view (see the section "Complex Objects") to specify any event(s) that will trigger an Alert rule (e.g.
Note that since queries to XNF objects are ultimately reduced to sets of normal queries joining several tables, our performance measurements on standard relational join queries represent the cost of retrieving a large, structured object.
