Bachman compared the Ptolemaic-to-Copernican change in astronomy to the change in computer programming in the early 1970s. When Bachman made the comparison in 1973, data processing was changing from a computer-centered view of information systems to a database-centered view. Bachman pointed out that the ancients of data processing wanted to view all data as a sequential stream of cards flowing through a computer (the computer-centered view). The change was to focus on a pool of data on which the computer happened to act (a database-oriented view).

Today it's difficult to imagine anyone thinking that the sun revolves around the Earth. Similarly, it's difficuly to imagine a programmer thinking that all data could be viewed as a sequential stream of cards.

Rake task to perform "view migrations" for using SQL Views with Rails. Avoids the need to copy or re-run multiple migrations when changes are made to queries providing view data.

Usage: rake db:views:load

Place SQL create statement for each view in a file as db/views/<view_name>.sql. Optionally include a numeric prefix such as 01_first_view.sql to order views that may have dependencies.

namespace :db do
  namespace :views do
    desc "Execute all stored View statements on DB connection"
