TMS Aurelius is a framework for Delphi which comes with support for data manipulation, complex or advanced queries, as well as inheritance and polymorphism.

Aurelius brings all benefits an application can obtain from using an ORM framework:
· Productivity: Avoid complex SQL statements that can only be verified at runtime. Code directly with objects.
· Maintainability: Clearer business logic by dealing with objects, hiding all the database-access layer.
· Portability: Easily change the underlying database - all your business code stays the same since they are just pure objects.

Features :

Several database servers supported (MS SQL Server, Firebird, MySQL, DB2, Interbase, Oracle,...)
Several database-access components supported (dbExpress, AnyDac, SQLDirect, ADO, IBX,...)
Multi-platform solution - Win32, Win64, Mac OS X, VCL, FireMonkey
Saving, updating and loading of entity objects in an object-oriented way
TAureliusDataSet for easy and fast interfacing to DB-aware controls in VCL
Queries - Powerful query API using criteria expressions, projections, grouping, conditions and even logical operators in a LINQ-like approach
Inheritance mapping and polymorphism - map a full class hierarchy into the database
Cross-database development - use a single Delphi code to target multiple databases in a transparent way
Choose from classes-to-database approach (creating the database structure from classes) or database-to-classes approach (creating classes source code from database, using TMS Data Modeler )
Mapping directly in classes using custom attributes
Association mapping
Lifetime management of objects using object manager
Cached and identity-mapped objects
Automatic database structure generation
Nullable types support
Lazy loading for associations and blob fields
Allows logging of SQL commands
