  1. Firebird 3 Database Encryption Support

    In Firebird 3.0 release there is an option to encrypt the whole database (http://firebirdsql.org/file/documentation/release_notes/html/en/3_0/rnfb30-security-encryption.html).
    For the encryption of the database you need a plugin (like this one that is working with AES128 from https://www.ibphoenix.com/products/software/encryptionplugin).
    To open an encrypted database you just have to send the encryption key via a callback function "setDBCryptCallback" to the Firebird server.
    My idea is if it's possible that the IBDAC component would be upgraded with the functionality to automaticly pass a setted "encryption_password" parameter (maybe there will be a need to have also a paramter for setting the Encryption library).

  4. New version for Odac

    Delivery a new version of Odac with just 2 classes, TOraSession and TOraQuery. That product would be more dry out and more cheap, reaching a biggest number of users.

    OraQuery allows execution of both SQL Query and StoredProc, as well as many other things, therefore there is no essential difference between the edition with TOraSession and TOraQuery and the Standard Edition. So if you need a cheaper edition, you can use the Standard Edition.

    Such functionality is implemented in IBDAC.

    Here is a code example:

    IBCTransaction.IsolationLevel := iblCustom;
    IBCTransaction.Params.Clear;
    IBCTransaction.Params.Add(‘wait’);
    IBCTransaction.Params.Add(‘read_committed’);
    IBCTransaction.Params.Add(‘rec_version’);

    The same can be done in the desing-time using the transaction component’s designer form.

  10. Better ODAC Locate() functionality

    Currently a call to Locate pulls back all the data locally, and with large tables this can take an extremely long time.
