A Course In In-memory Data Management

RRP $271.99

Recent achievements in hardware and software development, such as multi-core CPUs and DRAM capacities of multiple terabytes per server, enabled the introduction of a revolutionary technology: in-memory data management. This technology supports the flexible and extremely fast analysis of massive amounts of enterprise data. Professor Hasso Plattner and his research group at the Hasso Plattner Institute in Potsdam, Germany, have been investigating and teaching the corresponding concepts and their adoption in the software industry for years.

This book is based on an online course that was first launched in autumn 2012 with more than 13,000 enrolled students and marked the successful starting point of the openHPI e-learning platform. The course is mainly designed for students of computer science, software engineering, and IT related subjects, but addresses business experts, software developers, technology experts, and IT analysts alike. Plattner and his group focus on exploring the inner mechanics of a column-oriented dictionary-encoded in-memory database. Covered topics include - amongst others - physical data storage and access, basic database operators, compression mechanisms, and parallel join algorithms. Beyond that, implications for future enterprise applications and their development are discussed. Step by step, readers will understand the radical differences and advantages of the new technology over traditional row-oriented, disk-based databases.

In this completely revised 2nd edition, we incorporate the feedback of thousands of course participants on openHPI and take into account latest advancements in hard- and software. Improved figures, explanations, and examples further ease the understanding of the concepts presented. We introduce advanced data management techniques such as transparent aggregate caches and provide new showcases that demonstrate the potential of in-memory databases for two diverse industries: retail and life sciences.

Memory As A Programming Concept In C And C++

RRP $428.99

The overwhelming majority of bugs and crashes in computer programming stem from problems of memory access, allocation, or deallocation. Such memory related errors are also notoriously difficult to debug. Yet the role that memory plays in C and C++ programming is a subject often overlooked in courses and in books because it requires specialised knowledge of operating systems, compilers, computer architecture in addition to a familiarity with the languages themselves. Most professional programmers learn entirely through experience of the trouble it causes. This 2004 book provides students and professional programmers with a concise yet comprehensive view of the role memory plays in all aspects of programming and program behaviour. Assuming only a basic familiarity with C or C++, the author describes the techniques, methods, and tools available to deal with the problems related to memory and its effective use.


Foundations Of Computer Science

Foundations of Computer Science: From Data Manipulation to Theory of Computation successfully provides students with an overview of the many specializations within the field of computer science. Although many incoming freshman students are familiar with computers, they are often unaware of the broad field of computer science beyond the task of programming. Behrouz Forouzan has developed a five-part approach to introduce students to different aspects of the discipline without overwhelming them with technical detail. These topics include computer and data, computer hardware, computer software, data organization, and advanced topics. Throughout the book, Forouzan emphasizes the concept rather than the mathematical model, and difficult topics are supplemented with visual aids as needed to help students grasp concepts.


Martyrdom And Memory

Martyrs are produced, Elizabeth Castelli suggests, not by the lived experience of particular historical individuals but by the stories that are later told about them. And the formulaic character of stories about past suffering paradoxically serves specific theological, cultural, or political ends in the present. "Martyrdom and Memory" explores the central role of persecution in the early development of Christian ideas, institutions, and cultural forms and shows how the legacy of Christian martyrdom plays out in today's world.

In the pre-Constantinian imperial period, the conflict between Roman imperial powers and the subject Christian population hinged on competing interpretations of power, submission, resistance, and victory. This book highlights how both Roman and Christian notions of law and piety deployed the same forms of censure and critique, each accusing the other of deviations from governing conventions of gender, reason, and religion. Using Maurice Halbwachs's theoretical framework of collective memory and a wide range of Christian sources -- autobiographical writings, martyrologies and saints'lives, sermons, art objects, pilgrimage souvenirs, and polemics about spectacle -- Castelli shows that the writings of early Christians aimed to create public and ideologically potent accounts of martyrdom. The martyr's story becomes a "usable past" and a "living tradition" for Christian communities and an especially effective vehicle for transmitting ideas about gender, power, and sanctity.

An unlikely legacy of early Christian martyrdom is the emergence of modern "martyr cults" in the wake of the 1999 shootings at Columbine High School. Focusing specifically on the martyr cult associated with one of the victims, "Martyrdom and Memory" argues that the Columbine story dramatically expresses the ongoing power of collective memory constructed around a process of rendering tragic suffering redemptive and meaningful. In the wake of Columbine and other contemporary legacies of martyrdom's ethical ambivalence, the global impact of Christian culture making in the early twenty-first century cannot be ignored. For as the last century's secularist hypothesis sits in the wings, "religion" returns to center stage with one of this drama's most contentious yet riveting stars: the martyr.
