DBIS : a view by Subsystem or by Business Object

DBIS Software is a representation of the bank as a "living" system in interaction with the outside world,
but autonomous in its organization and its evolution.

Figure 1. The Bank as a System

DBIS Software structures the bank into four main systems.
Navigation principles are identical in each of them.
To illustrate the scenario, we choose the Production System.
Two approaches to read DBIS are possible:

• One follows an approach by Subsystem (anchors: a view by Subsystem),
• the other by Business Object (anchors: a view by business object).

These two approaches are complementary and DBIS allows at any time during the navigation to switch from one to the other.
Documented Navigation means that text boxes are available to specify a definition, characteristics and links appropriate for each DBIS item or component.

Here are some screens to illustrate the easiness and richness of DBIS.

[Notations used. An explanation in order to facilitate the reading of the following scenario.
- The macro-functionalities or "use cases" are represented by ellipses and the arrows illustrate the interactions between the macro-functionalities and "the actors" - people, other macro-functionalities, systems

- The elementary functionalities are represented by rectangles which are generally read from top to bottom to express a "cycle" of processing. The elementary classes are presented within "object models" which are generally read from top to bottom and the "levels of stabilization of the data" expressed horizontally. The lines feature relationships between elementary classes, and their cardinalities are noted in the form of * for a 0... N relationship, and nothing for a 1..1 relationship. ]
