1. What’s new in version 5 of GAUDI
LHCb Software Week
5-7 July 2000
P. Mato / CERN
The following are few slides intended to trigger a discussion/brainstorming with the goal of producing an Architecture for the DCS kernel.
Definition on Architecture: “The architecture of a system is the structure of the system”. Two main ingredients: A set of building blocks, and a set of collaborations that specify how those building blocks cooperate to provide various system functions.
An DCS architecture will allow us to provide set of control applications or control systems that fulfill a range of needs within the DCS domain. An architecture encourages reuse.
Analogies in the real world: Gothic architecture, Lego Basic® architecture, Lego Technique® architecture.
“To be successful, an object-oriented project must craft an architecture that is both coherent and resilient and then must propagate and evolve the vision of this architecture to the entire development team”, G. Booch, Object Solutions.
