From the developer:
Jailer is a tool for database subsetting, schema, and data browsing. It exports consistent, referentially intact row-sets from relational databases. The tool removes obsolete data without violating integrity. It is DBMS agnostic (by using JDBC), platform-independent, and generates DbUnit datasets, hierarchically structured XML, and topologically sorted SQL-DML.
You may want to check out more Mac applications, such as JAIL RUN 3D 2014 HD, 4D Budget or Wild West Quest: Dead Or Alive, which might be related to Jailer.
