1.Global expressed in the following form: name ^ (index 1, index 2, the subscript 3, .....)
如：^AirPlane(“Manufacturer”,“Address”,“Country”)=“US”
Multi-dimensional arrays stored in the form of a tree, each node of which correspond directly to disk and data blocks in memory, it is possible to achieve fast access speed. On this basis, we will multidimensional arrays mapped to objects or relational format, are accessible by the object-oriented interface or SQL-based interface.
Example:
set ^Y(3,6,7) = "third"
set ^Y(3,6,8) = "fourth"
set ^Y(3,6,7,8,4) = "fifth"
set ^Y(3,6,7,8,9) = "sixth"
