It only means that they come into the realm of feasibility as repository technology becomes a reality.”

“Business System Planning and Business Information Control Study are representative of enterprise analysis tools that are growing in importance and are likely to become mandatory for ant business that continues to grow and evolve.”

“the architect's drawings a transcription of the owner's perceptual requirements.”
