Overview of this book

Are you an experienced C++ developer eager to take your skills to the next level? This updated edition of Expert C++ is tailored to propel you toward your goals. This book takes you on a journey of building C++ applications while exploring advanced techniques beyond object-oriented programming. Along the way, you'll get to grips with designing templates, including template metaprogramming, and delve into memory management and smart pointers. Once you have a solid grasp of these foundational concepts, you'll advance to more advanced topics such as data structures with STL containers and explore advanced data structures with C++. Additionally, the book covers essential aspects like functional programming, concurrency, and multithreading, and designing concurrent data structures. It also offers insights into designing world-ready applications, incorporating design patterns, and addressing networking and security concerns. Finally, it adds to your knowledge of debugging and testing and large-scale application design. With Expert C++ as your guide, you'll be empowered to push the boundaries of your C++ expertise and unlock new possibilities in software development.

Design patterns in data-intensive applications

This section will discuss the common uses of design patterns in data-intensive applications. We will not select patterns from those in the previous section to show as many patterns as possible. However, the patterns included in the previous section can have applications in data-intensive applications.

In this context, we will explore a data-intensive application that provides a real-time stock process and allows users to perform buy and sell operations. The system uses a database to store information and a C++ API to allow users to perform the operations. The performance of this application is key, as a small time difference can result in big monetary losses. To implement this application, we’ll consider five design patterns:

  • Proxy pattern: The proxy pattern can limit access to information. For example, it can be used to check users’ permissions and return results based on the customer level of access, from live...
