Database Subsetting Tool

Jailer is a tool for database subsetting, schema and data browsing. 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.
• Improves database performance by removing and archiving obsolete data without violating integrity.
• Generates hierarchically structured XML, topologically sorted SQL-DML and DbUnit datasets.
• Data Browsing. Navigate bidirectionally through the database by following foreign-key-based or user-defined relationships.
• Open Source. Entirely written in Java. Platform independent. DBMS agnostic.

• 2015-12-04 Support for oracle's ROWID pseudo-column.
• 2016-09-08 New "Export To" mode allows to export rows directly into a different schema in the same database.
• 2015-12-04 Support for oracle's ROWID pseudo-column.
• 2015-10-23 Release 5.0 introduces the ability to collect rows in a separate embedded database. This allows it to export data from read-only databases.
• 2011-07-20 Implemented the "Subset by Example" feature: Use the Data Browser to collect all the rows to be extracted and let Jailer create a model for that subset.
• 2010-04-15 A Data Browser has been introduced. Navigate bidirectionally through the database by following foreign-key-based or user-defined relationships.
• 2008-12-23 Jailer now supports the DbUnit flat XML dataset file format, thus allowing the users of the famous JUnit extension DbUnit to use the extracted data for unit testing.
• 2007-12-05 Version 2.0 comes with new graphical user interface.
