ODOS

Operational Distributed Object System

Extensible .NET application server, object server and development framework

separator

ODOS is a comprehensive platform that enables enterprise .NET development and deployment for n-tier environments.

ODOS simplifies data access, improves user-interface design, and enables rich on-demand applications to operate over the internet. It provides a complete migration path to, and support for, next-generation Microsoft technologies. The framework provides sophisticated object persistence, real-time object change distribution, client and server-side selective caching, advanced data binding, business rule validation, real time risk monitoring, support for offline/disconnected operations, and support for publishing and consuming Web Services, among its many features. It framework is addressing software development companies and institutions specialized in ERP, Decision Support and Command & Control Systems for State, Public Sector or Defense organizations.

Some of the advantages of ODOS framework usage are:

  • Code re-use
  • Write and test less code
  • Increase developers productivity
  • Reduce code maintenance
  • Reduce training tools and learning cost
  • Centralized upgradeable infrastructure
  • Business to System logical separation
  • Implementation time cut backs up to 80%
  • Implementation cost cut backs up to 60%
  • Reduced overall risk

The development process to follow when using the ODOS Framework to implement n-tier applications can be visualized at the following figure:

The specific development tasks for each application to be implemented and a simple view of the application’s architecture can be visualized at the following figures:
