Scope: This forum is dedicated to sharing ideas about the ORM-LITE modeling tool.
ORM-LITE is a new, light-weight, open-source ORM tool that implements most
of the ORM 2 notation. 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
In addition to ORM2 diagrams, the current release includes an Rmap algorithm, SQL
generation, and a relational tables diagram that is automatically created and updated by Rmap. The relational tables diagram provides a concise summary of an ORM model and makes it easier to demonstrate the value of ORM/Rmap.
Why the ORM community will find it of interest
of the ORM community would like to see a greater demand for ORM. We are promoting ORM by packaging ORM-LITE as an add-in to the GanttPV
project scheduling tool. Because GanttPV is downloaded
about 100 times per day, this strategy will put 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
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. For example, the current release contains an implementation of Rmap (the script is included and can be
modified as desired); an ORM to UML mapping algorithm is
in the works. A programming guide and object map for ORM-LITE are available in the Library.
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.
The current release of ORM LITE is available at http://pureviolet.net/ganttpv/orm/index/ or in the library section of this web site.
