Introducing Delphi ORM


Book Description

Discover the fundamental concepts of object-relational mapping (ORM) design, Aurelius’ basic features, and the practical applications of those features. In a series of tasks, you will be exposed to techniques and best practices that make the use of Aurelius easy and efficient. Furthermore, you’ll refine your analytical skills to sharpen your understanding of Delphi (Pascal), helping you write better code along the way. Introducing Delphi ORM explains that while database design is difficult, database programming (i.e., manipulating, extracting, filtering, and manipulating data) is even more difficult. ORM frameworks provide a simpler way for you to access and manage data in databases. You’ll see how they offer different levels of abstraction and tools to code data access in a database-agnostic way by introducing a layer between the application and the data access language (SQL, LINQ, and so on). By the end of the book, you will be confident in using a wide range of Aurelius features to allow you to get started with databases in a very short space of time. What You Will LearnGain the fundamentals of ORM frameworks and Aurelius for DelphiAchieve basic tasks, such as connecting to the database and adding, deleting, and updating records, using Aurelius Employ advanced database queries Use the TAureliusDataSet component Integrate with mobile platforms such as Android and iOSWork with the data modeler application Who This Book Is For Software developers starting with Aurelius or those who have some exposure to the framework.

MVVM in Delphi


Book Description

Dive into the world of MVVM, learn how to build modern Windows applications, and prepare for cross-platform development. This book introduces you to the right mindset and demonstrates suitable methodologies that allow for quick understanding of the MVVM paradigm. MVVM in Delphi shows you how to use a quick and efficient MVVM framework that allows for scalability, is of manageable complexity, and provides strong efficiency. One of the biggest challenges developers face is how to convert legacy and monolithic Delphi applications to the MVVM architecture. This book takes you on a step-by-step journey and teaches you how to adapt an application to fit into the MVVM design. What You Will Learn Gain the fundamentals of MVVM Visualize MVVM as a design philosophy Create easy-to-use frameworks for building your own MVVM applications Develop a methodology for converting legacy applications to the MVVM pattern Architect cross-platform and multi-lingual applications using the MVVM pattern Who This Book Is For Delphi developers with a good knowledge of Delphi or programming experience in a different language. In addition, this book is attractive to Delphi developers who want to modernize existing applications based on the MVVM design.




Learn Object Pascal with Delphi


Book Description

"Learn Object Pascal with Delphi" provides an introduction to the popular programming language that is used as the basis for many computer science programs and a wide range of professional software development projects. The book is organized around specific programming skills, such as defining constants, creating variables, declaring types, making decisions, looping, encapsulating routines into procedures, using arrays and records, and handling files. Among the elements that make this book perfect for beginning Delphi developers are Quick Check review questions to reinforce new concepts; Test Your Knowledge exercises for trying out newfound skills; and an appendix listing Object Pascal's reserved words. The companion CD-ROM puts you to work immediately with the complete Delphi 5.0 Standard Edition compiler ready for installation. The CD also contains the complete source code for all of the examples; trial versions of GLAD components; and a trial version of the UIL Security System from Unlimited Intelligence Limited. Warren Rachele is an application developer with over 15 years of experience writing code. He is the chief systems architect at The Hunter Group in Evergreen, Colorado, and an instructor at colleges in the Denver area. He is also a frequent contributor to the "Delphi Informant" and the author of "The Tomes of Delphi: Win32 Database Developer's Guide".




Object-oriented Programming in Pascal


Book Description

Rather than taking the more traditional "procedural" approach, the authors take an object-oriented approach from the start to teach introductory programming concepts. Focusing on effective use of objects, they concentrate on building programs from an object library, reusing the objects, and developing classes and methods.




Delphi in a Nutshell


Book Description

The opening chapters discuss the Delphi object model, runtime type information and concurrent programming, while the bulk of the book is a language reference with every keyword, directive, function, procedure, variable, class, method, and property that is part of Delphi Pascal.

Entity Framework Core in Action


Book Description

Summary Entity Framework Core in Action teaches you how to access and update relational data from .NET applications. Following the crystal-clear explanations, real-world examples, and around 100 diagrams, you'll discover time-saving patterns and best practices for security, performance tuning, and unit testing. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the Technology There's a mismatch in the way OO programs and relational databases represent data. Entity Framework is an object-relational mapper (ORM) that bridges this gap, making it radically easier to query and write to databases from a .NET application. EF creates a data model that matches the structure of your OO code so you can query and write to your database using standard LINQ commands. It will even automatically generate the model from your database schema. About the Book Using crystal-clear explanations, real-world examples, and around 100 diagrams, Entity Framework Core in Action teaches you how to access and update relational data from .NET applications. You'l start with a clear breakdown of Entity Framework, long with the mental model behind ORM. Then you'll discover time-saving patterns and best practices for security, performance tuning, and even unit testing. As you go, you'll address common data access challenges and learn how to handle them with Entity Framework. What's Inside Querying a relational database with LINQ Using EF Core in business logic Integrating EF with existing C# applications Applying domain-driven design to EF Core Getting the best performance out of EF Core Covers EF Core 2.0 and 2.1 About the Reader For .NET developers with some awareness of how relational databases work.
