Hybrid DB model for digital output archive system

Disclosed is a system for digital archive output system that can archive unlimited number of digital output forms and provide the high performance by combining two types of databases. One database (Database-A) has a high-speed searching function to run a search for the contents of digital output forms in a limited number of target forms. And, another database (Database-B) has the capability to manage unlimited number of files. Database-A has the copy of certain files that are in Database-B.

Database-A manages a part of digital output forms. Database-A can search text data from the output forms and edit the contents of output forms.

Database-B manages all digital output forms by their attributes such as form-id, form-title, form-date, etc. Database-B can select the output form from unlimited number of output forms. But Database-B doesn't access the contents of the output form.

This figure illustrates the relationship between Database-A and B.
