AB  - This study seeks to develop optimal measures that enable organizations or institutions to quickly
resume web services after performing database integration and migration following the new establishment or
modification of systems. Database integration was performed for multiple databases and instances by avoiding
schema collision for each character set and the database connection information of various Java-based web
services was analyzed. Using the information of new databases integrated with existing databases, connection
information mapping tables were derived for each user account. The mapping tables were used to design and
implement a conversion gateway for connection to new databases and web service migration was carried out.
When multiple web services require migration due to a change in the target database, the corresponding
database connection information of application programs for each service must be analyzed and services can
undergo migration after connection information is modified. This involves significant time and costs. This study
performed service migration by implementing a driver-level conversion gateway corresponding to the
connection process of databases without having to separately modify application programs for each service.
This method of migration allows organizations to resume web services in a shorter period of time. This quick
restoration of services contributes to service stability and business continuity, thereby greatly enhancing
business competitiveness. By implementing driver-level common functions for database connection resulting
from a change in the database server, fast and stable standard measures were presented for database
connection during migration.
