Supported Databases (MVCActiveRecord)

MVCActiveRecord works with any database supported by FireDAC. The RQL (Resource Query Language) compiler and SQL generator are available for the following databases:

DatabaseMinimum VersionNotes
PostgreSQL9.6+RETURNING clause, native UUID. Recommended: 13+
Microsoft SQL Server2012+OFFSET/FETCH pagination requires 2012. Recommended: 2019+
MySQL5.7+LAST_INSERT_ID, backtick quoting. MariaDB 10.2+ also supported
Firebird1.5+gen_id sequences, ROWS pagination. RETURNING clause requires 2.0+. Recommended: 3.0+ (IDENTITY columns)
InterBaseXE3+No RETURNING clause, uses gen_id sequences for auto-generated keys
SQLite3.8+last_insert_rowid, no sequences. Recommended: 3.30+
Oracle12c (12.1)+OFFSET/FETCH pagination, RETURNING clause, sequences via DUAL

Tip: Include MVCFramework.SQLGenerators in your project's uses clause to register all database backends at once. Alternatively, include only the specific generator you need (e.g. MVCFramework.SQLGenerators.PostgreSQL).

🔒 Security & TLS 1.3 Support

DelphiMVCFramework provides enterprise-grade security features including full TLS 1.3 support. The framework automatically negotiates the highest available TLS version and provides:

  • Perfect Forward Secrecy with modern cipher suites
  • Certificate validation and custom certificate handling
  • SNI (Server Name Indication) support for multiple SSL certificates
  • HTTP Strict Transport Security (HSTS) headers
  • Secure cookie handling with SameSite attributes
  • CSRF protection mechanisms

TLS 1.3 brings significant security and performance improvements, including faster handshakes and stronger encryption algorithms. DelphiMVCFramework leverages these improvements automatically when deployed in compatible environments.

🏁 Quick Start

Here's how a simple DMVCFramework controller looks like:

// 1. Create a controller
[MVCPath('/api/hello')]
TMyController = class(TMVCController)
public
  [MVCPath('/world')]
  [MVCHTTPMethod([httpGET])]
  function HelloWorld: TMyObject;
end;

// 2. Implement the action
function TMyController.HelloWorld: TMyObject;
begin
  Result := TMyObject.Create('Hello World!');
end;

// 3. Register and start server elsewhere
FMVC := TMVCEngine.Create(Self);
FMVC.AddController(TMyController);
