Domain-Driven Design

"Eric Evans has written a fantastic book on how you can make the design of your software match your mental model of the problem domain you are addressing. "His book is very compatible with XP. It is not about drawing pictures of a domain; it is about how you think of it, the language you use to talk about it, and how you organize your software to reflect your improving understanding of it. Eric thinks that learning about your problem domain is as likely to happen at the end of your project as at the beginning, and so refactoring is a big part of his technique. "The book is a fun read. Eric has lots of interesting stories, and he has a way with words. I see this book as essential reading for software developers-it is a future classic." -Ralph Johnson, author of Design Patterns "If you don't think you are getting value from your investment in object-oriented programming, this book will tell you what you've forgotten to do."Eric Evans convincingly argues for the importance of domain modeling as the central focus of development and provides a solid framework and set of techniques for accomplishing it. This is timeless wisdom, and will hold up long after the methodologies du jour have gone out of fashion." -Dave Collins, author of Designing Object-Oriented User Interfaces "Eric weaves real-world experience modeling-and building-business applications into a practical, useful book. Written from the perspective of a trusted practitioner, Eric's descriptions of ubiquitous language, the benefits of sharing models with users, object life-cycle management, logical and physical application structuring, and the process and results of deep refactoring are major contributions to our field." -Luke Hohmann, author of Beyond Software Architecture This book belongs on the shelf of every thoughtful software developer.--Kent BeckWhat Eric has managed to capture is a part of the design process that experienced object designers have always used, but that we have been singularly unsuccessful as a group in conveying to the rest of the industry. We've given away bits and pieces of this knowledge...but we've never organized and systematized the principles of building domain logic. This book is important.--Kyle Brown, author of Enterprise Java(TM) Programming with IBM® WebSphere®The software development community widely acknowledges that domain modeling is central to software design. Through domain models, software developers are able to express rich functionality and translate it into a software implementation that truly serves the needs of its users. But despite its obvious importance, there are few practical resources that explain how to incorporate effective domain modeling into the software development process.Domain-Driven Design fills that need. This is not a book about specific technologies. It offers readers a systematic approach to domain-driven design, presenting an extensive set of design best practices, experience-based techniques, and fundamental principles that facilitate the development of software projects facing complex domains. Intertwining design and development practice, this book incorporates numerous examples based on actual projects to illustrate the application of domain-driven design to real-world software development.Readers learn how to use a domain model to make a complex development effort more focused and dynamic. A core of best practices and standard patterns provides a common language for the development team. A shift in emphasis--refactoring not just the code but the model underlying the code--in combination with the frequent iterations of Agile development leads to deeper insight into domains and enhanced communication between domain expert and programmer. Domain-Driven Design then builds on this foundation, and addresses modeling

Decentralized Finance (DeFi) & Metaverse For Beginners 2 Books in 1 2022: The #1 Guide On Investing In Cryptocurrency, Bitcoin, Ethereum, Smart Contracts, Blockchain Gaming, Virtual Reality, NFT (eBook, ePUB)

Decentralized Finance (DeFi) 2022 Cryptocurrency's promise is to make money and payments all around accessible to anyone, regardless of where they are on the planet. The Decentralized Finance (DeFi) or Open Finance development makes that promise a stride further.Imagine a global, open option in contrast to each financial service you use today - investment funds, loans, trading, insurance and more are accessible to anybody in the world with a cell phone and internet connection. This is presently conceivable on smart contract blockchains, like Ethereum. Smart contracts are programs running on the blockchain that can execute consequently when certain conditions are met. These smart contracts empower developers to work undeniably with more modern functionality than essentially sending and accepting cryptocurrency. These projects are what we currently call decentralized apps or dapps. You can think about a dapp as an app that is based on decentralized innovation, instead of being built and constrained by a solitary, unified substance or organization. Become accustomed to this word, dapp, you'll be seeing it a ton from now into the foreseeable future.While a portion of these concepts may sound cutting edge, automated loans negotiated straightforwardly between two strangers in different parts of the world, without a bank in the center a large number of these dapps are now live today.. Metaverse For Beginners 2022 When people talk about the future, they usually mean virtual reality. The reason is that when you say "the future," most people think of science fiction, and nearly all SF takes place in a virtual space. The word metaverse is actually an old term for cyberspace-the virtual environment that exists on computers. So, you could argue that the metaverse and cyberspace are virtually the same things. The word metaverse originally meant just one thing: a synonym for the word universe. Now, it means a lot of things, some contradictory. Metaverse has the slick ring of the future around it, but in reality, it refers to past or present realities, not just a future vision. The term is thrown around so much that you can't trust what it means. What we call the metaverse might be better termed the internet-on-steroids or something more accurate and less sexy-sounding! The metaverse is a little bit like virtual reality, except not quite. It's a confusing term these days. That's because, in the 90s, Neal Stephenson (of Snow Crash fame) imagined the metaverse as a network of connected 3D spaces that users could interact with using VR goggles and haptic feedback devices. The metaverse is the general term for all digital universes being connected. We are just starting to build these worlds, and it's easy to get sidetracked by the technologies that we're using to build them, (which are sometimes quite new.) Just as an aside, remember how every startup in 1983 used a Commodore 64 as its main computer? Even with that amazing machine, no one really predicted anything like what the internet would become. Hey everyone, I'm doing a think piece that looks at the future of VR. I'm really interested to hear from people on this one! What would you like technology to do for you in the metaverse? What new activities and experiences do you most want developing? The main aim of this piece is to get a better understanding of what we actually want the future to be. The metaverse can't become real until someone builds it with code. Until then, the metaverse is whatever we imagine it to be while we are building it together.
