Scalable SQL and NoSQL Data Stores - Rick Cattell Home Page

In this paper, we examine a number of SQL and socalled “NoSQL” data stores designed to scale simple OLTP-style application loads over many servers. Originally motivated by Web 2.0 applications, these systems are designed to scale to thousands or millions of users doing updates as well as reads, in contrast to traditional DBMSs and data warehouses. We contrast the new systems on their data model, consistency mechanisms, storage mechanisms, durability guarantees, availability, query support, and other dimensions. These systems typically sacrifice some of these dimensions, e.g. database-wide transaction consistency, in order to achieve others, e.g. higher availability and scalability. Note: Bibliographic references for systems are not listed, but URLs for more information can be found in the System References table at the end of this paper. Caveat: Statements in this paper are based on sources and documentation that may not be reliable, and the systems described are “moving targets,” so some statements may be incorrect. Verify through other sources before depending on information here. Nevertheless, we hope this comprehensive survey is useful!

History Repeats Itself - EDBT
by prolato 0 Comments favorite 0 Viewed Download 0 Times

In this paper, I describe some of the recent developments in the database management area, in particular the NoSQL phenomenon and the hoopla associated with it. The goal of the paper is not to do an exhaustive survey of NoSQL systems. The aim is to do a broad brush analysis of what these developments mean - the good and the bad aspects! Based on my more than three decades of database systems work in the research and product arenas, I will outline what are many of the pitfalls to avoid since there is currently a mad rush to develop and adopt a plethora of NoSQL systems in a segment of the IT population, including the research community. In rushing to develop these systems to overcome some of the shortcomings of the relational systems, many good principles of the latter, which go beyond the relational model and the SQL language, have been left by the wayside. Now many of the features that were initially discarded as unnecessary in the NoSQL systems are being brought in, but unfortunately in ad hoc ways. Hopefully, the lessons learnt over three decades with relational and other systems would not go to waste and we wouldn’t let history repeat itself with respect to simple minded approaches leading to enormous pain later on for developers as well as users of the NoSQL systems! Caveat: What I express in this paper are my personal opinions and they do not necessarily reflect the opinions of my employer.

Al Qaeda and the Taliban - Institute for Middle Eastern Democracy

This paper examines the complex, often misunderstood, relationship between al-Qaeda, the Taliban and the various militant groups found in FATA (the Federally Administered Tribal Areas) in Pakistan, including the TTP (Tehrik-i-Taliban Pakistan). Much of what is commonly assumed about the Taliban, the TTP and al-Qaeda is based on misinformation, misunderstanding or a misrepresentation of historical events. The Taliban and alQaeda can in many ways be seen as sharing common values, although their ultimate goals remain very different. The Taliban were not part of the mujahedeen fighting against the Soviets in Afghanistan, and emerged only in 1994. Al-Qaeda, for all the conspiracy, did not receive money from the CIA during the 1980s, and was only officially formed as an organisation in 1988. The creation of the TTP in 2007 is another matter, and was created as an umbrella organisation for various Pakistani militant groups, and maintains close ties with al-Qaeda. However, the Pakistani Taliban is not the same Taliban as the one formed in 1994, and although it swears its loyalty to Mullah Omar, its goals differ from that of the Afghani Taliban. We can speak of al-Qaeda and the Taliban in two broad strokes – pre 9/11 and post 9/11. The attacks on the Twin Towers and the Pentagon (as well as the failed attack on Washington DC with the hijacked flight 93), was the culmination of al-Qaeda as a tightly knit, hierarchical organisation. The subsequent “War on Terror” and the invasion of Afghanistan in October 2001 destroyed much of its organisational capacity; it also left the Taliban severely weakened. However, they both regrouped in the FATA region over a period of years, and al-Qaeda spread its ideology throughout northern Pakistan, coalescing with militant groups and local warlords. Before 9/11, al-Qaeda and the Taliban were very much two different organisations; today, it is not so simple, and in 2010, General David Petreus claimed that there is “a symbiotic relationship between all of these different organizations: al-Qaeda, the Pakistani Taliban, the Afghan Taliban ... They support each other, they coordinate with each other, sometimes they compete with each other, [and] sometimes they even fight each other.” (cfr, 2010, http://www.cfr.org).

How to find And Acquiring Fabulous Books

There are various fantastic novels, like silke, you can go through throughout your free time. In fact, it will not be simple to distinguish the favorable types through the average literature. Could very well be asking yourself how you are likely to find that novel that you might curl track of on top of your chair. Here are several tricks. The synopsis will often be found at the back manage or located on the essential flap associated with the book. You get a specific concept of whatever the narrative will probably be and what exactly the people are similar to, by checking this. This can certainly be useful in picking out the manual that will actually help keep you entertained.

Algebra 2 and Trigonometry - Forest Hills High School

Algebra 2 and Trigonometry is a new text for a course in intermediate algebra and trigonometry that continues the approach that has made Amsco a leader in presenting mathematics in a modern, integrated manner. Over the last decade, this approach has undergone numerous changes and refinements to keep pace with ever-changing technology. This textbook is the final book in the three-part series in which Amsco parallels the integrated approach to the teaching of high school mathematics promoted by the National Council of Teachers of Mathematics in its Principles and Standards for School Mathematics and mandated by the New York State Board of Regents in the Mathematics Core Curriculum. The text presents a range of materials and explanations that are guidelines for achieving a high level of excellence in their understanding of mathematics. In this book: ✔ The real numbers are reviewed and the understanding of operations with irrational numbers, particularly radicals, is expanded. ✔ The graphing calculator continues to be used as a routine tool in the study of mathematics. Its use enables the student to solve problems that require computation that more realistically reflects the real world. The use of the calculator replaces the need for tables in the study of trigonometry and logarithms. ✔ Coordinate geometry continues to be an integral part of the visualization of algebraic and trigonometric relationships. ✔ Functions represent a unifying concept throughout. The algebraic functions introduced in Integrated Algebra 1 are reviewed, and exponential, logarithmic, and trigonometric functions are presented. ✔ Algebraic skills from Integrated Algebra 1 are maintained, strengthened, and expanded as both a holistic approach to mathematics and as a bridge to advanced studies. ✔ Statistics includes the use of the graphing calculator to reexamine range, quartiles, and interquartile range, to introduce measures of dispersion such as variance and standard deviation, and to determine the curve that best represents a set of bivariate data.
