Feature overview

Benefits

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.
  It's basically something that prevents you from writing code like this:
  

  Query1.Sql.Text := 'SELECT I.ID AS INVOICE_ID, I.INVOICE_TYPE, I.INVOICE_NO, I.ISSUE_DATE, I.PRINT_DATE, ' +
    'C.ID AS CUSTOMER_ID, C.CUSTOMER_NAME, C.SEX, C.BIRTHDAY, N.ID AS COUNTRY_ID, N.COUNTRY_NAME' +
    'FROM INVOICE AS I INNER JOIN CUSTOMER AS C ON (C.ID = I.CUSTOMER_ID) ' +
    'LEFT JOIN COUNTRY AS N ON (N.ID = C.COUNTRY_ID)' +
    'WHERE I.ID = :INVOICE_ID;'
  Query1.ParamByName('INVOICE_ID').AsInteger := 1;
  Query1.Open;
  ShowMessage(Format('Invoice No: %d, Customer: %s, Country: %s',
    [Query1.FieldByName('INVOICE_NO').AsInteger,
    Query1.FieldByName('CUSTOMER_NAME').AsString,
    Query1.FieldByName('COUNTRY_NAME').AsString])); 

  and instead write this:
  

  Invoice := Manager1.Find<TInvoice>(1);
  ShowMessage(Format('Invoice No: %d, Customer: %s, Country: %s',
    [Invoice.InvoiceNo, Invoice.Customer.Name, Invoice.Customer.Country.Name]));

• 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.

Feature details

• Several database servers supported (MS SQL Server, Firebird, MySQL, DB2, Interbase, Oracle,...)
• Several database-access components supported (dbExpress, AnyDac, SQLDirect, ADO, IBX,...)

• 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 )

Comments

I've played with the trial of Aurelius a bit and I like what I've seen so far (Firebird 2.5 with IBObjects). Especially the way how I can get started with a legacy database is nice. I wouldn't like if Aurelius thinks it needs to be clever when it comes to maintaining the underlaying database for changes due to the technical challenges mentioned above. For sure, Aurelius has potential for being an important part in the Delphi world when writing OO-based database clients.
