>No more workareas, Set Database or Create Session. No more ambiguous data management.
>No more housekeeping (close data, etc.) The objects manage the data they represent.
>Encapsulated Data.
>Sharing data among forms is much easier.
>Almost complete control over if, and under what conditions, data gets written to disk.
>Flush is now granular, right down to the rowset level.
>Programmatic control over login.
>Rowset-level events that fire for appends, edits, changes, abandons and deletes.
>Field-level events that fire before datalink and after changes.
>Explicit control over the datalink itself.
>Finally! - the ability to freeze or refresh datalinked controls at will.
>Morphing.
>Filter Mode
>Scalability.
>Business rules move away from the User-Interface.
>Field level custom methods.
>Data-level validation.
>"Live" calculated fields.
>Heterogeneous data access (multiple data engines simultaneously)
>and most important of all:
>Object data - with all its benefits of reusability and inheritance.
