The record

Purpose: DTM Schema Comparer compares and synchronizes database schemas, including tables, columns, views, indexes, triggers, keys, comments and stored procedures.
Visual comparison: Schemas are shown as trees with synchronous navigation, and comparison results use red, green and yellow indicators for different, orphaned and equal objects.
Synchronization: The tool can compare or synchronize an entire schema or a selected part and can create a .SQL synchronization script without performing synchronization.
Automation: GUI and command-line modes support batch files, schedulers and Windows Task Scheduler integration.
Database connectivity: Supported unified interfaces are ODBC, IDAPI and OLE DB, with native Oracle Call Interface support also available.
Multivendor databases: The product can compare MySQL with Microsoft SQL Server or Sybase schemas and DB2 with Microsoft SQL Server or MySQL schemas.
Text comparison: It includes a built-in database-object text comparison tool and can use an external text comparison tool.
Filtering: MySQL schema object and owner/schema filtering supports exclude and include options.
Integration: The MySQL-focused page states that DTM Schema Comparer directly integrates with DTM Data Comparer.
Reporting: The product provides HTML comparison reports with three levels of information presentation.
Platform limits: The download page lists Win32 Unicode and x64 Unicode demo builds, and the system requirements list Windows XP through Windows 10 desktop editions plus Windows Server versions.
Privacy and security: DTM soft says its free, demo and commercial products contain no adware or spyware and collect no information unless user-activated logging is enabled.
Support: DTM soft technical support may request ERROR.LOG files for technical purposes and says the information is not provided to third parties.
Licensing: A single license permits one installation on one computer, with a second copy allowed for the primary user's portable computer.
