Understand the design, construction and operation of data centres with this easy-to-use reference. Data centres are spaces where computer systems, physical network technology and associated components are housed, operated and monitored, and any industry or business that employs computer systems or networked systems at any scale will interact with data centres. Data centres are complex and expensive to build and operate, and successful project delivery requires a wide range of specialised knowledge and skills. This accessible reference lays out the requirements for creating these essential facilities. Data Centre Essentials is a comprehensive survey of the essential principles of data centre design, construction and operation. It is designed to provide those involved in a data centre project or providing professional service deliverables to the data centre industry but do not have a technical background or deep sector experience with the understanding required to participate in such projects. The non-technical language and thorough engagement with key considerations make it ideal for anyone looking to understand one of the pillars of a digital society.

Databases have become an integral part of modern-day life. We live in an information-driven society and database technology has a direct impact on our daily lives. Decisions are routinely made by organizations based on the information collected and stored in the databases. Because databases play such an important role in business and society, database programming is a key skill. In addition to database management systems, in order to effectively apply and implement databases in real industrial or commercial systems, a good Graphic User Interface (GUI) is needed to enable users to access and manipulate their records or data in databases. Visual C#.NET is an ideal candidate to be selected to provide this GUI functionality. Unlike other programming languages, Visual C#.NET is a language that has a number of advantages, such as being easy to learn and easy to understand with relatively shallow learning curves. Beginning with Visual Studio.NET 2003, Microsoft integrated a number of programming languages, such as Visual C++, Visual Basic, C# and Visual J#, into a dynamic model called .NET Framework which makes Internet and Web programming easy and simple .Any language integrated in this model can be used to develop professional and efficient Web applications that can be used to communicate with others via the Internet. ADO.NET and ASP.NET are two of the most important sub- models of .NET Framework.

Data analysis has been a hot topic for a number of years, and many future data scientists have backgrounds that are relatively light in mathematics. This slim volume provides a very approachable guide to the techniques of the subject, designed with such people in mind. Formulae are kept to a minimum, but the book's scope is broad, introducing the basic ideas of probability and statistics and more advanced techniques such as generalised linear models, classification using logistic regression, and support-vector machines. An essential feature of the book is that it does not tie to any particular software. The methods introduced in this book could also be implemented using any other statistical software and applying any major statistical package. Academically, the book amounts to a first course, practical for those at the undergraduate level, either as part of a mathematics/statistics degree or as a data-oriented option for a non-mathematics degree. As a data scientist you will be using the computer to perform the data analysis. Any programming language should be able to carry out the analyses that we describe. We used R (because it is free); our code is available as an accompaniment to the book.
