Ready to master SQL and ace your dream job interview? Dive into "Grokking the SQL Interview," your passport to SQL expertise! Uncover the secrets to crafting powerful queries, mastering joins, and acing real-world SQL interviews? Are you on the brink of a career in data analytics, database administration, or software development? Perhaps you're gearing up for a crucial job interview that hinges on your SQL skills. If so, "Grokking the SQL Interview" is your essential companion on the path to SQL mastery and interview success. As a Java developer who has cleared SQL interviews, I can attest that SQL interviews are not easy, given the vast nature of SQL and the variety of concepts and topics it covers. When I was preparing for Java interviews, I was looking for a resource where I learn and prepare SQL questions from a programmer’s perspective rather than a DBA, but I couldn’t find any. Grokking the SQL Interview is my effort to fill that gap and become an excellent resource for anyone looking to master SQL and prepare for SQL interviews. Whenever I prepare for Java Interview, I always prepare about SQL and Linux; these are everywhere. That’s why I decided to cover essential topics from an interview perspective when I thought to write about this book.

Discover critical considerations and best practices for improving database performance based on what has worked, and failed, across thousands of teams and use cases in the field. This book provides practical guidance for understanding the database-related opportunities, trade-offs, and traps you might encounter while trying to optimize data-intensive applications for high throughput and low latency. Whether you are building a new system from the ground up or trying to optimize an existing use case for increased demand, this book covers the essentials. The book begins with a look at the many factors impacting database performance at the extreme scale that today’s game changing applications face—or at least hope to achieve. You’ll gain insight into the performance impact of both technical and business requirements, and how those should influence your decisions around database infrastructure and topology. The authors share an inside perspective on often-overlooked engineering details that could be constraining—or helping—your team’s database performance.

The complete guide to learning everything you need to know about Apache Ignite. This book is addressed to anyone interested in learning in-memory computing and distributed database. It is useful for developers and architects new to Apache Ignite as well as those who already use any other in-memory databases and want to expand their knowledge. The Apache Ignite is a memory-centric distributed database, caching and computing platform for developing the data-intensive application to scale out to hundreds of millions of transactions per seconds and petabyte of in-memory data. This next generation memory-centric platform can function as an in-memory data grid, or it can be deployed as a full functional persistence data store with SQL and ACID transaction support. The main mantra of the Apache Ignite platform is to keep the entire dataset into in-memory and on disk, boost application performance by providing caching capabilities and processing data in parallel. Such a paradigm has been identified as the answers to problems of traditional disk-based database performance since it can load and execute all the necessary datasets in memory. This paradigm eliminates the substantial number of disk I/O, which hamper transactions and create a performance bottleneck for the traditional database systems.

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.
