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
-base. |
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.
