Data selection act

摘要

In today's 'write-once/read-maybe' culture 80 per cent of business event data is never accessed after being stored; and it is never modified by one user, let alone by many. So do we use relational database technology (RDB) simply because it's there? Similarly, there is significant marketing hype about the need to share native CAD data, and many vendors have multiple translation facilities to enable data sharing — but why? Unless your process acts specifically on the 3D data for analysis, rapid prototyping or machining, sharing is unnecessary. In fact, to preserve the intellectual property of your design it is actually desirable to limit the extent to -which the detailed data is made available to third parties.
