SQL BIG DATA
Hadoop, the big yellow elephant that has become synonymous with big data, is here to stay. SQL (Structured Query Language), the language invented by IBM in the early 1970s, has been with us for the past 45-plus years or so. SQL is the most popular data language, and it is used by software engineers, data scientists, and business analysts and quality assurance professionals whenever they interact with data. This book discusses the marriage of these two technologies. It consolidates SQL and the big data landscape. It provides a comprehensive overview, at a technology and architecture level, of different SQL technologies on big data tools, products, and solutions. It discusses how SQL is not just being used for structured data but also for semistructured and streaming data. Big data tools are also rapidly evolving in the operational data space. The book discusses how SQL, which is heavily used in operational systems and operational analytics, is also being adopted by new big data tools and frameworks to expand usage of big data in these operational systems
