    ORM2 is the latest generation of object–role modeling. The main objectives for the ORM 2 graphical notation are: [6] More compact display of ORM models without compromising clarity; Improved internationalization (e.g. avoid English language symbols) Simplified drawing rules to facilitate creation of a graphical editor

    Suppose a vector norm ‖ ‖ on and a vector norm ‖ ‖ on are given. Any matrix A induces a linear operator from to with respect to the standard basis, and one defines the corresponding induced norm or operator norm or subordinate norm on the space of all matrices as follows: ‖ ‖, = {‖ ‖: ‖ ‖ =} = {‖ ‖ ‖ ‖:} . where denotes the supremum.
