A New Application Framework Design
This is a draft document - it can be changed at any time by anyone.
Document Purpose
This document is intended to introduce a high level design of an application framework for the Apache Open for Business project.
Overview
The application framework will be written in Java and it will provide the basic structure to write an application. The framework will provide the following basic functionality:
- Configuration.
- Globalization (locale, time zone, currency).
- Logging.
- Security (authentication/authorization).
- Persistence (file system or database).
- Services.
- Runtime management.
Design Goals
- Single jar file.
- Compact, small memory footprint.
- Scalable from SBCs to enterprise-class ERP systems.
- Reuses existing technologies.
Easy to configure and maintain.
Design Participants Note
Please take some to watch this presentation by Joshua Bloch: How to Design a Good API & Why it Matters.
