EVOLUTION TO THE DW2.0 ENVIRONMENT

  • From the standpoint evolution of architecture it is interesting to look backward and to examine the forces that shaped the evolution. In fact there have been many forces that have shaped the evolution of information architecture to its highest point – DW 2.0
  • Some of the forces of evolution have been:

1)        The demand for more and different uses of technology: when one compares the very first system to those of DW 2.0 one can see that there has been a remarkable upgrade of systems and their ability to communicate information to the end user. It seems almost inconceivable that not so long ago output from computer system was in the form of holes punched in cards. And end user output was buried as a scrap of information in a hexadecimal dump. The truth is that the computer was not very useful to the end user as long as output was in the very crude from in which it originally appeared.

2)        Online processing: as long as access to data was restricted to very short amounts of time, there was only so much the business person could do with the computer. But the instant that online processing became a possibility, the business opened up to the possibilities of the interactive use of information intertwined in the day – to – day life of the business. With online processing, reservation systems, bank teller processing, ATM processing, online inventory management, and a whole host of other important uses of the computer became a reality.

3)        The hunger for integrated, corporate date: As long as there were many applications, the thirst of the office community was slaked. But after it was recognized that something important was missing, what was missing was corporate information. Corporate information could not be obtained by adding together many tiny little applications. Instead data had to be recast into the integrated corporate understanding of information. But once corporate data became reality whole new vistas of processing opened up.

4)        The need to include unstructured textual data in the mix: for many year decisions were made exclusively on the basis of structured transaction data. While structured transaction data is certainly important, there are other vistas of information in the corporate environment. There is a health of information tied up in textual, unstructured format. Unfortunately unlocking the textual information is not easy. Fortunately, textual ETL (extract/transform/load) emerged and gave organizations the key to unlocking text as a basis for making decisions.

5)        Capacity: if the world of technology had topped marking innovations, a sophisticated world such as DW 2.0 simply would not have been possible. But the capacity of technology, the speed with which technology works, and the ability to interrelate different forms of technology work all capacity is an infrequently encountered constraint imagine a world in which storage was held entirely on magnetic tape(as the world was not so long ago.) Most of the types of processing that are taken for granted today simply would not have been possible.

6)        Economics: In addition to the growth of capacity, the economics of technology have been very favorable to the consumer. If the consumer had to pay the prices for technology that were used a decade ago, the data warehouses of DW 2.0 would simply be out of orbit from a financial perspective. Thanks to Moore’s law the unit cost of technology has been shrinking for many years now. The result is affordability at the consumer level.
