Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Database Administrators

Managing application-level C4I data and maintaining the common operational picture on GCCS-M provides an operational data-management foundation for retraining in database administration.

How to prepare: Build database-administration skills through a practice-database lab that exercises access controls, software upgrades, security measures, and change testing. Modifying DBMS software, assigning user privileges, administering user-access levels, software upgrades, and database security measures are civilian DBA duties in O*NET, but are not documented military duties for this NEC.

What the civilian work involves

Plan and install upgrades of database management system software to enhance database performance.
Specify users and user access levels for each segment of database.
Test changes to database applications or systems.
