The meaning and the concept of the term is
Identification for each system
Since the meanings and concepts of the terms
are identified by the dictionary, it is possible to
prevent fluctuation of the meaning
Since it is difficult to handle multiple languages,
a translation function is required separately
It can register in the dictionary more than once
in multiple languages, It is possible to respond
according to each.
For data exchange between databases,
it is necessary to reconstruct the data structure.
By cross-referencing the dictionary data items,
it is unnecessary to reconstruct the existing data
When adding new items to the database, it is ne
-cessary to rebuild the database.

Items can be freely added to classified in advance.
For new classifications, it is possible to construct
it as a new dictionary on the basis of the previous
dictionary, and cope with it by multiple reading of
the dictionary.
The database can be rebuilt.

Database using dictionary can not be redefined.
For example, even discontinued information can
-not be deleted. (discontinued product)
For similar product search of other company's
products, it is necessary to repeat the same
search for each product catalog database.
Data of the items of the product catalog instructed
from the dictionary information can be extracted from
the associated database group (horizontal search)
The stored information does not have genealogy
information such as item, class, parentage relationship.
Genealogy information is added by dictionary informa
-tion. Therefore, classification search becomes possible.
