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.

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.

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.

This book was originally written to support an introductory course in Object Orientation through the medium of Smalltalk (and VisualWorks in particular). However, it can be used as a book to teach the reader Smalltalk, to introduce object orientation as well as present object oriented design and analysis. It takes as its basic premise that most Computer Scientists I Software Engineers learn best by doing rather than from theoretical notes. The chapters therefore attempt to introduce concepts by getting you the reader to do things, rather than by extensive theoretical discussions. This means that these chapters take a hands-on approach to the subject and assume that the student/reader has a suitable Small talk environment available to them. The chapters are listed below and are divided into six parts. The reader is advised to work through Parts 1 and 3 thoroughly in order to gain a detailed understanding of object orientation. Part 2 then provides an introduction to the Smalltalk environment and language. Other chapters may then be dipped into as required. For example, if the reader wishes to hone their Smalltalk skills then the chapters in Part 4 would be useful. However, if at that point they wish to get on and discover the delights of graphical user interfaces in Smalltalk, then Part 5 could be read next. Part 6 presents some more advances subjects such as metaclasses and concurrency which are not required for straight forward Small talk development.

Diagramming and process are important topics in today’s software development world, as the UML diagramming language has come to be almost universally accepted. Yet process is necessary; by themselves, diagrams are of little use. Use Case Driven Object Modeling with UML - Theory and Practice combines the notation of UML with a lightweight but effective process - the ICONIX process - for designing and developing software systems. ICONIX has developed a growing following over the years. Sitting between the free-for-all of Extreme Programming and overly rigid processes such as RUP, ICONIX offers just enough structure to be successful.
