The Changing Of The Technology Guard: NoSQL + Hadoop` suggests that the technology landscape is shifting with Big Data, and NoSQL and Hadoop are becoming increasingly important. Traditional databases like Oracle and Teradata may be too expensive and ill-suited for typical big data tasks, while Hadoop addresses a smaller portion of the database market, specifically the OLAP market. In contrast, NoSQL databases like MongoDB are addressing the larger OLTP market, which is home to operational databases that can help enterprises put their data to work in real-time, making it a key area of focus for the fastest growing Big Data community and second hottest job trend after HTML5.
