DataBaseliner is a tool that allows a self contained subset of data to be extracted from a database. By defining key seed data to extract and setting up relationships dataBaseliner will extract a slice of data from a source database that is completely referentially integral and output this as a SQL script that can be run into development and test schemas.

DataBaseliner is written using Java and jdbc to connect to databases, as such it can work with any database that provides a compliant jdbc driver. As different drivers and databases have different idiosyncrasies and requirements for SQL generation a flexible extension mechanism is used to add support for different databases. Support for each database is provided as a separate jar.

DataBaseliner is configured using an xml document that defines how to connect to the database, what data to extract and how tables relate to each other.
