ORM LITE is a
light-weight, open-source ORM tool that implements most of the ORM 2 notation.
New: Rmap, SQL, Sample Data. Please try out the beta release and help us to improve this new,
introductory-level ORM tool.
What’s New in v0.11a?
The most important
change is that sample data can now be entered for fact types. The quick start
documentation has been updated to describe important keyboard short cuts. Several
bugs have been fixed. To upgrade v0.11 files, run the new “Install ORM Diagram”
The Rmap and SQL
generation are much improved over last release. We have implemented a new
Relational Tables diagram that is automatically created and updated by Rmap.
The generation of names is much improved. Indices are created for most
uniqueness constraints. The implementation includes table baseline and
The Relational Tables
diagram was added because it provides a concise summary of the ORM model and
because we felt that the value of ORM/Rmap would be easier to understand and
demonstrate through experimentation with a visual representation.
ORM LITE was created
to help popularize ORM. It is open source software, so it can be shared at no
cost. It is completely self-contained, so it is easy to install. It is
cross-platform, working on Windows, Macintosh, Linux, and Unix. When users are
ready to upgrade to an industrial strength tool, NORMA is recommended.
By packaging ORM LITE
as a GanttPV add-in, we are putting an ORM tool into the hands of 100 new
project managers each day. As more project managers learn about ORM, more teams
will adopt it. ORM LITE includes a brief introduction to ORM and points users
to the ORM Foundation web site for more information.
ORM LITE is
scriptable. It is hoped that ORM practitioners will be interested in using ORM
LITE to develop and test new ORM related algorithms.
ORM LITE works with
the GanttPV Server. This makes it easy to share models among team members.
Model changes are tracked and can be shared via the server.
