StructureOpenERP is a web application, it is a web server that handles the business logic and communicates with the database application. The clients interact with the application using a web interface. The server part of OpenERP is written in Python programming language, the web part is written in Javascript.
 

ModulesBusiness features are organised into modules. A module is a folder with a pre-defined structure containing Python code and XML files. A module defines data structure, forms, reports, menus, procedures, workflows, etc... Modules can also contain web components written in Javascript.
Database

OpenERP uses PostgreSQL as database management system.

The documentation is also managed using this service but a website dedicated to all publications has been set up in 2009.

Development environment
Module development mainly relies around edition of Python and XML files. Some application logic (i.e. workflows and data structure) can be changed through the client interface.
