EntityDAC Professional is an advanced Object-Relational Mapping (ORM) framework developed by Devart specifically for Delphi developers. It maps database tables directly to Delphi classes and introduces full support for Language Integrated Query (LINQ) to simplify database-independent application development. Core Architecture & Mapping
Comprehensive OOP Mapping: Enables object-relational mapping of database structures into Delphi classes while maintaining complete compatibility with standard object-oriented programming concepts like polymorphism, encapsulation, and inheritance.
Flexibility with Base Classes: You can map database structures to custom classes inherited from standard TObject, meaning you can integrate EntityDAC into existing heritage projects without being strictly locked into inheriting from a custom frame base class.
Three-Way Mapping Choices: Developers can configure mapping mechanisms via explicit code mapping, attribute-based mapping, or external XML mapping files. The Professional Edition Advantage
While Devart provides Express and Standard editions of EntityDAC, the Professional Edition unlocks critical design-time features and runtime tools for enterprise applications:
Design-Time Control Bindings: Features specialized data-aware components, such as TEntityTable and TEntityQuery, designed to bind control architectures straight to user interfaces at design-time.
The Entity Developer Bundle: Includes the Professional Tier of Devart Entity Developer, a visual ORM model designer tool. It automates the generation of database models (Database-First), models to databases (Model-First), or class schemas into active application data footprints (Code-First) without manual XML or code-attribute typing.
Source Code Tier Availability: By purchasing the specific Professional Edition with Source Code, software creators gain absolute access to the complete source code files for all component classes and underlying data providers. Key Technical Performance Features
Advanced Engine LINQ Queries: LINQ functions natively as a database-independent execution platform, validating query structures during app compilation and utilizing standard Delphi Code Completion helpers to minimize code syntax errors.
Entity & Query Caching: To provide high-performance operations compared to basic Data Access Components, EntityDAC caches database metadata, query results, and loaded entity identities to minimize redundant roundtrip database requests.
Enterprise Relationships: Built-in support for lazy loading of specific records, complex Table-per-Type (TPT) and Table-per-Hierarchy (TPH) structural mapping, cascade save/delete sequences, and complex associations (One-to-One, One-to-Many, Many-to-Many). If you are planning a project, let me know: Which IDE version of RAD Studio/Delphi you are using?
What database engines (e.g., SQL Server, Oracle, PostgreSQL, MySQL) you need to connect to?
Whether you are building a brand-new application or adding an ORM layer to an existing legacy codebase?
