Practical process patterns: SOS

Description

Pattern SOS – synchronisation of sources. This PPT should be downloaded to see the animation. More details in my blog.

Transcript

• Each connection should

• follow the common access rules (data protection)

• be traceable

• be coordinated

• be secure (data transportation)

• be reliable (operation)

• be effective

• be normalised

• Real complexity n(n-1)/2

Synchronisation of sources (SOS): N to N data exchange problem 2009-08-25 Practical processs patterns Source 1 Source 2 Source 3 Source 4 Source 5

• Coordination service provides

• central coordination

• single source for common rules (data protection)

• audit trails

• operational visibility

• Real complexity 2(n+1)
