Download or read book Event Based Programming written by Ted Faison and published by Apress. This book was released on 2011-12-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now available in paperback— Languages like C#, VB .NET, and Delphi include built-in support for events, and these events become very powerful when they connect the objects and components of a system. Events make it possible for such parts to interact without any coupling. And the resulting parts can be developed and tested individually which keeps the code clean and simple. Component-based development (CBD) is an extension of object-oriented programming. CBD does away with the language and vendor-specific limitations of OOP, makes software reuse more practical and accelerates the development process. Event-based programming is the next logical step in CBD, and makes components more reusable due to their decoupled nature. But event-based systems are easier to develop, which means they're cheaper and more reliable than traditional OOP or CBD systems. This book teaches you how to develop software based on parts that interact primarily through an event mechanism. You'll learn how to use events in many different situations, to solve recurring development problems without coupling. The book introduces Signal Wiring Diagram, a novel form of software diagram similar to the circuit diagrams used by hardware designers. The book concludes with a series of case studies, incorporating all featured concepts. In a nutshell, you'll want to pick up a copy of this book because it: Shows how to use an event-based paradigm to reduce or completely eliminate coupling between classes and components Describes components, including coordinators, workers, builders, binders, and routers Contains three complete case studies that model concepts being used to design small, medium, and large systems

Download or read book Delphi Event based and Asynchronous Programming written by Neven Prasnikar, Jr and published by . This book was released on 2021-02-07 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Event-based programming is everywhere. Nowadays, you can hardly write any kind of application without leaning on events and messages.This simple, yet extremely powerful mechanism is also the cornerstone of asynchronous and multithreaded programming. Without events, we would not know when some task was completed.But, asynchronous and multithreaded programming consists of more than just handling multiple threads, protecting shared resources, and synchronization. It also includes designing and understanding program flow. That design aspect is often forgotten, taken for granted, and solving all the fine-grained nuances of multithreaded programming hogs the spotlight.Without understanding asynchronous flow and the bigger picture it can be hard to properly solve all the other issues, including multithreading. What used to be plain spaghetti code, now becomes temporal spaghetti.You can lose control over your objects, have bits of code creating and releasing them all over the place, even without adding multithreading into the mix. Memory leaks, crashes, and holding references to dead data long after its destruction are perfectly possible even in a singlethreaded environment.While the starting point of this book is giving a proper introduction to event-based and asynchronous programming flow and design, it also provides the necessary implementation details, explanations and code examples needed to put those designs into practice.

Download or read book Practical Microservices written by Ethan Garofolo and published by Pragmatic Bookshelf. This book was released on 2020-04-09 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: MVC and CRUD make software easier to write, but harder to change. Microservice-based architectures can help even the smallest of projects remain agile in the long term, but most tutorials meander in theory or completely miss the point of what it means to be microservice-based. Roll up your sleeves with real projects and learn the most important concepts of evented architectures. You'll have your own deployable, testable project and a direction for where to go next. Much ink has been spilled on the topic of microservices, but all of this writing fails to accurately identity what makes a system a monolith, define what microservices are, or give complete, practical examples, so you're probably left thinking they have nothing to offer you. You don't have to be at Google or Facebook scale to benefit from a microservice-based architecture. Microservices will keep even small and medium teams productive by keeping the pieces of your system focused and decoupled. Discover the basics of message-based architectures, render the same state in different shapes to fit the task at hand, and learn what it is that makes something a monolith (it has nothing to do with how many machines you deploy to). Conserve resources by performing background jobs with microservices. Deploy specialized microservices for registration, authentication, payment processing, e-mail, and more. Tune your services by defining appropriate service boundaries. Deploy your services effectively for continuous integration. Master debugging techniques that work across different services. You'll finish with a deployable system and skills you can apply to your current project. Add the responsiveness and flexibility of microservices to your project, no matter what the size or complexity. What You Need: While the principles of this book transcend programming language, the code examples are in Node.js because JavaScript, for better or worse, is widely read. You'll use PostgreSQL for data storage, so familiarity with it is a plus. The books does provide Docker images to make working with PostgreSQL a bit easier, but extensive Docker knowledge is not required.
