Report recommendations to appropriate DBA specialist and/or technical services. • Review results of database integrity checks. Resolve identified issues. • Design appropriate strategy to reorganize database objects to release unused space or repair fragmentation. • Install database management software in any environment • Install database patches and service packs in any environment. • Provide maintenance, support, and assistance to specialist DBAs with installation and configuration of clustered database failover, database replication solutions, and database backup solutions. • Review, install, analyze, and implement security patches to be applied to remain Payment Cared Industry (PCI) compliant, vendor compliant, and Michigan Cyber Security compliant. • Designs the security model based on set standards. Create database user accounts and schemas in production environments based on defined and approved forms and procedures. • Define/design roles and profiles. • Recommend standard password security policies. • Implement data encryption. • Design, configure, and initiate auditing with appropriate options as needed. • Create and deploy new database in development and test environments. • Ensures and validates the integrity and quality of the scripts to be promoted to any of the environments. • Provide guidance to systems analysts, based on documented standards, in creating and modifying application specific database objects. • Perform Data Export/Import/Load and data transformations between databases in production environments. • Perform production data file transfers between different systems, across state agencies, federal government, vendors, etc. • Analyze and resolve database space utilization in production environments.
