OES Enterprise wiki

OES is a platform for building line-of-business applications: stock, accounting, payroll, sales. This wiki is the user's guide: what the platform is, how to install and build it, how to make a first application, and how the parts fit together.

Contents

Getting started

1. Introduction: what OES is, and the words used throughout
2. Installation: download a build and start it
3. Building from source: build it yourself on Windows, Linux or macOS
4. First steps: a small stock application, from an empty base to a report

Working in the designer

5. The designer: the window, the menus, saving and running
6. The metadata tree: every kind of object a configuration is made of
7. Forms: what the user sees, and how it is bound to data
8. Modules and the language: where code lives and what it looks like
9. Queries and reports: reading data back

Running it

10. Application server: serving bases without a window
11. How the platform is built: programs, libraries, databases
12. Pitfalls: what goes wrong, and what to do
