The term Big Data has existed in some form or another for years but recently has taken on a new and more official meaning. In today’s world of massive internet applications, digital instruments streaming non-stop data, scientific data collection and fraud detection, Big Data has grown far beyond what even a large company used to consider large – into the hundreds of terabytes or even petabytes. Furthermore, Big Data has a large unstructured component to it, whether comments on websites, blog data, internet usage, images or documents. This kind of information typically does not map well to traditional database technologies which rely on a very structured table/column arrangement.
Considering high volume and great variability of data, along with very high uptime and extremely short response times needed, traditional RDBMSs simply won’t work – they will not be able to scale out to provide 1 second response time when a Facebook user posts a picture or visits a friend’s wall when there are millions of users looking at petabytes of data. Thus, completely different kinds of data access and storage technologies are needed, ones which are designed to scale far beyond even a very powerful systems such as Oracle ExaData.
This article discusses Oracle’s view of Big Data and in particular how it pertains to Data Warehousing and Business Intelligence. Keep in mind there are many offerings and capabilities pertaining to the acquisition and use of Big Data which are well beyond the scope of Data Warehousing and BI systems; I’m going to focus on just a slice of it here.
