Design and manufacturing of computer chips is a advanced technology. It is a very complex process, capital intensive, requires large investments in plant and production machines which deal with 0.18 micron technology. Current technology uses micro-electronics of about 0.35 micron using aluminum as conductors, 0.25 micron sizes using copper as conductors of electrons. In near future the technology of 0.10 micron with copper and even nano-electronics will be used to make computer chips. Aluminum conductors will be phased out by copper on computer chips, as copper is a better conductor of electrons.
Table below shows the progress and future advancement trends of computer chips.
In fact, any person in this world with a small low-cost PC can create a Oracle database server system. If 10 people work for a year than it is 10 man-years spent. It will be a great advantage to take the existing code and add missing features or enhancements to PostgreSQL and start using it immediately.
