Готов поделится с сообществом рядом слухов, на счет того, что ждет нас с выходом 10.1:
"- in Progress 10.1 there will be true object orientation
- you can
define classes in the 4GL
- inheritance
- overriding
- interfaces
- Progress assumes
apps will use a gui front end from Microsoft
- the Progress IDE is moving to Eclipse
-
Eclipse is a Java open-source framework good for developing
project-based IDEs like Visual
studio - www.eclipse.org
- he showed a Progress IDE developed with Eclipse
- there was 4GL
code in the editor
- I guess the idea is to write Progress 4GL Web Services with this IDE
and use Microsoft or something else for your app's GUI
- the new object orientation will fit
into this IDE
- Dynamics (using smart objects) has just finished some features
and there will
be no new development for it.
- I guess Progress guru Arthur Fink was right -
"smart
programmers do not use Smart Objects"
- he emphasized the Progress ProDataSet
- a 4GL object
which holds a set of records from related tables
(e.g. a customer, with his invoices, with
their line items)
- he held up a big book about ProDataSet which I think he wrote
- it is
in the Progress documentation online apparently
- this is a lot like Microsoft's Object Spaces,
which was going
to be in ADO.NET V2.0, but is delayed a long time, or abandoned
- he said
there would be a single method for converting between
the ProDataSet and a big XML with the
same data
- an obvious help in developing Web Services
- the bulk of his talk of the Progress
future was on Service Orientation
- using Progress to write Web Services
- designing apps for
Service Orientation
- running the apps in the Sonic ESB Enterprise Service Bus"
В подтверждение предыдущей инфы есть отдельный топик в программе exchange2005:
During this session you'll learn how an application constructs a user-defined object in the 4GL and how this object can extend the behavior of other application-defined objects as well as implement functionality defined in interfaces. Join us as we explore how the Progress 4GL supports constructors and destructors, strongly typed object handles, overriding and polymorphism.

Суммируя и резюмируя все вместе взятое: нас ждет OOP4GL, который поставит жирный крест на ADM*/Dynamics и многих других framework'ах, которые люди написали, чтобы компенсировать отсутствие OOP в P4GL. По поводу вымирания предыдущих технологий от PSC сейчас на peg.com ведется интенсивное обсуждение этой животрепещущей темы, т.к. многие, как я понял, серьезно вложились в эти технологии.
У кого есть дополнительная инфа, а также комментарии, делитесь
Представители PT от вас в первую очердь интересно услышать какие-либо комментарии
