Overview of this book

FireMonkey (FMX) is a cross-platform application framework that allows developers to create exciting user interfaces and deliver applications on multiple operating systems (OS). This book will help you learn visual programming with Delphi and FMX. Starting with an overview of the FMX framework, including a general discussion of the underlying philosophy and approach, you’ll then move on to the fundamentals and architectural details of FMX. You’ll also cover a significant comparison between Delphi and the Visual Component Library (VCL). Next, you’ll focus on the main FMX components, data access/data binding, and style concepts, in addition to understanding how to deliver visually responsive UIs. To address modern application development, the book takes you through topics such as animations and effects, and provides you with a general introduction to parallel programming, specifically targeting UI-related aspects, including application responsiveness. Later, you’ll explore the most important cross-platform services in the FMX framework, which are essential for delivering your application on multiple platforms while retaining the single codebase approach. Finally, you’ll learn about FMX’s built-in 3D functionalities. By the end of this book, you’ll be familiar with the FMX framework and be able to build effective cross-platform apps.

Introducing Tables, Query, StoredProc, and Command

TFDTable, TFDQuery, and TFDStoredProc provide a dataset interface to data retrieved from a database system, each with some peculiarities. They are obviously very common components in data-centric applications, together with TFDCommand, which can be used to execute SQL statements and is largely used in the implementation of FireDAC adapters (the intermediate objects that translate dataset-like operations to SQL-like statements).

All the typical functionalities, such as master/detail mechanisms, macros and parameters, cached update support, local filtering and sorting capabilities, metadata retrieval, persistence capabilities, aggregates, and advanced functionalities such as the LocalSQL technology, are available to all FireDAC datasets (TFDTableTFDQuery, and TFDStoreProc). Some of them are also available for TFDMemTable and TFDCommand (which slightly diverge from the other components).

We will cover some...
