In the previous chapter, we have seen why data warehousing is essential for enterprises, of all sizes in all industries. We have reviewed how businesses are reaping major benefits from data warehousing. We have also discussed the building blocks of a data warehouse. You now have a fairly good idea of the features and functions of the basic components and a reasonable definition of data warehousing. You have understood that it is a fundamentally simple concept at the same time you know it is also a blend of many technologies. Several business and technological drivers have moved data warehousing forward in the past few years.
Before we proceed further, we are at the point where we want to ask sonic relevant questions. What is the current scenario and slate of the market? What businesses have adopted data warehousing? What are the technological advances? In short what at the signets-nt trends.
It is too early in our discussion of the subject to talk about trends? The usual practice is to include a chapter on future trends towards the end, almost as an afterthought.
The reader typically glosses over the discussion on future trends. This chapter is not so much like looking into the crystal hall for possible future happenings: we want to deal with the important current trends that arc happening now.
It is important for you to keep the knowledge about the current trends as a backdrop in your mind as you continue the deeper study of the subject. When you gather the informational requirements for your data warehouse, you need to be aware or the current trends. When you get into the design phase you need to be cognizant of the trends. When you implement your data warehouse. You need to that your data warehouse is in line with the trends, knowledge of the trends is important and necessary even at a fairly early stage of your study. In this chapter we will touch upon most of the major trends. You will understand how and why data warehousing continues to grow and become more and more pervasive. We will discuss the trends in vendor solutions and products. We will relate data warehousing with other technological phenomena such as the Internet and the Worldwide Web. Wherever More detailed discussions are necessary, we will revisit some or the trends in later chapters.
