About the book
A complete view of the book.
FireDAC in Practice follows the development of a data-access layer from the first connection to the decisions that sustain a production application. Rather than presenting isolated components, it shows how queries, parameters, types, transactions, and updates relate to consistency, performance, and user experience.
Across six parts, readers progress through in-memory data, Cached Updates, Local SQL, batch processing, concurrency, pooling, diagnostics, recovery, and deployment. Delphi examples with different relational databases reveal the distance between code that merely works in a laboratory and a solution capable of remaining dependable under load, failure, and continuous change.
The challenge
Does this situation sound familiar?
Making a query work is only the first step. In production, connections, transactions, concurrency, performance, failures, and database differences turn apparently simple decisions into risks for the entire system.
The book’s approach
Keep data access reliable beyond the first query.
Explore FireDAC progressively, from architecture and driver configuration to queries, transactions, in-memory data, concurrency, security, recovery, and deployment.
“The value of a data-access library appears both in what it delivers and in how the system recovers.”
By the end of the book, you will be able to:
✓Understand FireDAC architecture, drivers, and configuration
✓Write parameterized queries and handle data types correctly
✓Control transactions, master-detail relationships, and updates
✓Use in-memory data, caching, and Local SQL with clear criteria
✓Measure performance and handle concurrency and asynchronous execution
✓Prepare security, recovery, and deployment for production
Questions that guide the reading
Answers begin with the right questions.
Questions explored through context, criteria, and examples.
How do parameters, types, transactions, and updates affect correctness?
When do caching and in-memory processing help—or create risk?
How can a data layer be prepared for concurrency, failure, and deployment?
Inside the book
A structured journey that helps you move forward.
Concepts and applications presented in a coherent sequence.
Foundations and the first connection
Understand the architecture, drivers, connections, and configuration behind the first successful access.
Queries and commands
Build parameterized queries and commands while respecting types, errors, and database behavior.
Transactions and relationships
Coordinate transactions, master-detail relationships, and updates without losing consistency.
In-memory data and updates
Use FireDAC memory, cached updates, and Local SQL where they add measurable value.
Performance and concurrency
Evaluate concurrency, pooling, asynchronous work, and bottlenecks with evidence.
Security, recovery, and deployment
Protect credentials and data, recover from failure, and prepare dependable deployment.
What makes this book different
Depth to understand. Clarity to keep moving forward.
21 chapters using RAD Studio 13 Florence, Delphi 13, and Firebird 5 as the main references
The FireStore case study and complete examples in a public repository
Decision matrices, exercises, and deliberately induced failures to verify behavior
Comparisons with SQLite, PostgreSQL, and MySQL with explicit limits and guarantees
