CASE approach in telecom. software development

Alcatel has a worldwide connection network which allows full integration between all their software development environments. This is based on several mainframes which are connected to a central one. A number of workstations are connected to each mainframe. The integration allows flexible management of the software development. Supported by this distributed environment the automation of the software development reaches full application. A CASE environment integrates a set of tools which allows a designer to follow the life cycle of the software allocated to him while the complete or partial control of the software project can be done from a centralised point. Moreover, every developer has access to a central library where he can find software objects at all levels of the life cycle. The authors have a tools integration platform S12DE (System 12 Development Environment) which is composed of two parts: ARCADE (Alcatel Reusable Computer Aided Development Environment) which runs on a workstation and the LCMS (Local Configuration Management System) running on an IBM mainframe, collecting all the items coming from each workstation
