"It’s not easy to find such a generous book on big data and databases. Fortunately, this book is the one." Feng Yu. Computing Reviews. June 28, 2016. This is a book for enterprise architects, database administrators, and developers who need to understand the latest developments in database technologies. It is the book to help you choose the correct database technology at a time when concepts such as Big Data, NoSQL and NewSQL are making what used to be an easy choice into a complex decision with significant implications. The relational database (RDBMS) model completely dominated database technology for over 20 years. Today this "one size fits all" stability has been disrupted by a relatively recent explosion of new database technologies. These paradigm-busting technologies are powering the "Big Data" and "NoSQL" revolutions, as well as forcing fundamental changes in databases across the board. Deciding to use a relational database was once truly a no-brainer, and the various commercial relational databases competed on price, performance, reliability, and ease of use rather than on fundamental architectures. Today we are faced with choices between radically different database technologies. Choosing the right database today is a complex undertaking, with serious economic and technological consequences. Next Generation Databases demystifies today’s new database technologies. The book describes what each technology was designed to solve. It shows how each technology can be used to solve real word application and business problems. Most importantly, this book highlights the architectural differences between technologies that are the critical factors to consider when choosing a database platform for new and upcoming projects. Introduces the new technologies that have revolutionized the database landscape Describes how each technology can be used to solve specific application or business challenges Reviews the most popular new wave databases and how they use these new database technologies

Employers who don’t adapt to the expectations of younger generations are losing top talent, as they leave for positions at companies with modern practices. Learn what companies need to do to fit into the new normal in the workplace. Generation Y sees the world differently than any other generation in modern memory, and nowhere is this more evident than in the workplace. The shifts that this generation has seen in the economy, technology, and the world have changed what they want from life and work--which is not a 9-5 existence for forty-plus years, leading to a typical retirement at sixty-five. What older generations call a poor work ethic from a spoiled generation, Gen Y sees as a different way of doing things. Companies that take the time to listen realize that what Gen Y is asking for isn’t that crazy; in fact, it’s better in many ways such as: A demand for work-life balance isn’t a cry for fewer work hours--it’s a cry to be able to work from outside the office beyond a rigid 9-5 schedule (which can lead, to Gen Y employees working even more hours than you expected). Leaving a job after a couple years isn’t an inability to commit--it’s a need to learn more, expand their experience, and develop their career at a faster pace, which is helpful to companies that hire those individuals, including your own. Elevating nontraditional benefits over financial benefits is a step toward creating an emotional connection to the company where employees spend most of their time and invest mental and emotional efforts. The need to work for a company with a purpose reflects the power that social media has on the social consciousness. Next Generation Leadership will explore what’s behind these shifts in the character of the emerging workforce. It shows that, as Gen Y assumes managerial positions, the nature of leadership and business will change over the next few decades in irrevocable and profound ways.

The world of education is being radically altered with the change being driven by technology, openness, and unprecedented access to knowledge. Older correspondence-style methods of instructional delivery are passé and “classroom adapted to the web” approaches to learning are often ineffective and do little to harness the transformational potential of technology. E-Learning scenarios, mobile technologies, communication and information access, and personal learning environments are becoming mainstream and, as a result, control of the learning process is shifting away from institutions and into the hands of learners. This volumes promotes a forward-thinking agenda for research and scholarship that highlights new ideas, deep insights, and novel approaches to “unconstrained” learning.

There is no HR-related topic more popular in the business press than performance management (PM). There has been an explosion in writing on this topic in the past 5 years, condemning it as a failure and calling for fundamental change. The vast majority of organizations use the same basic process which I call “Last Generation Performance Management” or PM 1.0 for short. Despite widespread agreement that PM 1.0 is failing, few companies have abandoned it or made fundamental changes to it. While everyone agrees it is broken, few agree on how to fix it. Companies continue to tinker with their systems, making incremental changes every few years with no lasting improvement in effectiveness. Employees continue to achieve amazing things in organizations every day, despite this process not because of it. Nothing has worked because organizations, business leaders and HR professionals focus on PM practices instead of the fundamental purpose of PM and the paradigms, assumptions, and beliefs that underlie the practices. Companies ask their performance management process to do too many things and it fails at all of them as a result. At the foundation of PM 1.0 practices is the ideology of a meritocracy and paradigms rooted in standard economic and psychological theories. While these theories were adequate explanations for motivation and behavior in the 19th and 20th centuries, they fail to account for the increasingly complex nature of organizations and their environments today. Despite the ineffectiveness of PM 1.0, there are powerful forces holding it in place. Information on rigorous, evidence-based recommendations is crowded out by benchmarking information, case studies of high-profile companies, and other propaganda coming from HR think tanks and consultants. Business leaders and HR professionals learn about common practices not effective practices. This book confronts the traditional dogma, paradigms, and practices of PM 1.0 and holds them up to the bright light of scientific scrutiny. It encourages HR professionals and business leaders to abandon PM 1.0 and it offers up a more appropriate purpose for PM, alternative paradigms to guide them and practical solutions that are better supported by scientific research, referred to as “Next Generation Performance Management” or PM 2.0 for short.
