Expanding the Repertoire of Process-based Tool Integration

Valetto, Giuseppe

The purpose of this thesis is to design and implement a new protocol for tool enveloping, in the context of the Oz Process Centered Environment. This new part of the system would be complementary to the already existing Black Box protocol for Oz and would deal with additional families of tools, whose character would be better serviced by a different approach, providing enhanced flexibility and a greater amount of interaction between the human operator, the tools and the environment during the execution of the wrapped activities. To achieve this, the concepts of persistent tool platforms, tool sessions and transaction-like activities will be introduced as the main innovative features of the protocol. We plan to be able to encapsulate and service conveniently classes of tools such as interpretive systems, databases, medium and large size applications that allow for incremental binding of parameters and partial retrieving of results, and possibly multi-user tools. Marginal modification and upgrading of the Oz general architecture and components will necessarily be performed.
