Project Summary
Jailer is a tool for database subsetting and sampling, schema browsing, and rendering. It exports consistent, referentially intact row-sets from relational databases. It 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.
Features
* Exports consistent and referentially intact row-sets from your productive database and imports the data into your development and test environment.
