ODB Database Viewer not only enables you to create and manage local .odb databases, but also allows you to connect to and manage almost all popular database engines: MySQL/MariaDB, MS Access, PostgreSQL, Oracle, MS SQL Server, and more.
Note: if you use the default HSQLDB Embedded database (.ODB file), you need to install Java (JRE/JDK) on your PC. You can find why and how from the link below.
