The IBM Sterling Database Query Client is available as a part of the IBM Order Management (SaaS offering) .
This database query interface is available as an HTTP Client and can be accessed using the following URL: https://<ip>:<port>/smcfs/yfshttpdbi/sterlingdbqueryclient.jsp

This tool aims to assist System Implementers (SI), Administrators and IBM Support personnel to query the remote database easily and securely on an on-demand basis to examine the actual data to assist their analysis. It also eliminates the need to setup third party database browsing tools.

The security aspects of granting the right access, ensuring no alteration of content and so on are at the disposal of the administrators. It is recommended to restrict the access for DB Query tool and control the queries invoked here, as retrieving huge amount of data may impact the application server and performance of the environment.
