TOMAS - MORPHOLOGICAL APPROACH
TO INFORMATION SYSTEM DESIGN
TOMAS is developed by use of morphological
approach to the development of information systems. The designer of
TOMAS is author of that approach, as well.
Morphological approach to information
system design is based on the following propositions:
There is an invariant structure for
all information systems consisting out of the:
set of entities and atributes relevant
for the object system, i.e. for the user organization
set of structural links between these
set of flows of material, money, work
and information and states that are results of those flows.
For all organizations of the same type
- e.g. factories - there is common structure of:
flows and contents of information
typical problem situation
major decisions to be made.
For a given level of information technology
and given type of organization, one can determine:
algorhytms for database handling
set of information to be generated by
set of user and system procedures.
This makes possible development of
prefabricated information systems.
This makes possible the development
of information meta systems that could support several types of organizations,
and/or organizations that include various types of business.
Some business functions have the same
structure in various types of organizations, e.g.
finance, human resources etc.
approach to information system design ensures development of information
systems with superior quality and low costs.
