Logical databases have a tree-like structure, which can be defined as follows: ·There is a single node at the highest level. This is known as the root node. ·Each node can have one or more …

In most existing logical databases, the nodes make reference to database tables whose data is read by the logical database and passed to a program for further processing. It is possible, …

The logical tree structure is the internal (integration node) representation of a message. It is also known as the message assembly. When a message arrives at an integration node, it is …
