    Hi,
    1. internal data organization and data structure:
    http://www.peg.com/techpapers/monogr...ma/schema.html

    2. data types:
    decimal, character, integer, date, logical, recid.

    3. concurrency control:
    3 modes of retrieving records: NO-LOCK - equivalent of READ_UNCOMMITTED transaction isolation level, SHARE-LOCK - equivalent of REPEATABLE_READ; EXCLUSIVE-LOCK - equivalent of SELECT ... FOR UPDATE.

    4. DDL
    There is no DDL. You can modify logical db structure by loading *.df file with schema changes definitions.

    5. Very efficient, far more better than SQL-92 standard. I think that you need documentation for Progress as ypou mentioned very broad range of subjects concerning Progress technology.

    Regards
    Bogdan
