DataObjects README

DataObjects.rb is an attempt to rewrite existing Ruby database drivers to conform to one, standard interface.

At present, PostgreSQL, MySQL and SQLite drivers are available. More drivers are currently under development. If you feel like living on the edge, install and test drivers directly from this repository.

Introduction

To connect and send queries to databases, DataObjects relies on native extensions. Native extensions have been written in both C (for the Ruby MRI platform) and Java (for the JRuby platform). Individual drivers may include extensions for both Ruby MRI and JRuby, or one or the other.

C extensions have been written using according to each vendor API. Java drivers use the standard JDBC API. Although there are dialectical differences between the Java drivers, the JDBC API ensures a reasonable amount of commonality. As such, the Java extensions rely on a common do_jdbc_support gem, which wraps code that is common to all of the Java extensions.

Installation

To install a driver from the repository cd into the driver directory and use the provided rake install task to install for the default platform.

If a driver includes extensions for both MRI or JRuby platforms, you can be explicit about which platform you wish to install the extension for as follows:

rake install:mri
jruby -S rake install:jruby

Copyright and Licensing

Please see the copyright notices in each individual driver README or LICENSE file. Java-based drivers bundle JDBC driver JAR files, which may be provided under a license that is more restrictive than the MIT License used by the data_objects gem itself.
