Subject: Adaptiveness
Cc: info@odmg.org, lieber@ccs.neu.edu

Adaptiveness in object-oriented databases

After reading the exchange of ideas between Won Kim and ODMG in 
Object Magazine (Sept. 1994), I would like to bring the work
on AQL (a variant of OQL) to your attention. AQL is relevant to 
the ODMG and SQL3 efforts.

The basic novel idea is to use adaptive queries
(and programs) which are both shorter and more flexible.
The adaptiveness property is achieved through succinct subgraph
specifications. The adaptive approach has been shown to be
effective to simplify oo programming and also seems useful 
for query languages and to define views.

The AQL paper is available from:

ftp://ftp.ccs.neu.edu:/pub/people/lieber/adaptive-query-lang.ps

using either xmosaic or anonymous ftp. The abstract is below.

If you are close to Boston, you are invited to come to the defense.

    AQL: An Adaptive Query Language for Object-Oriented Databases

                             Abstract

Object-oriented database query languages strive for simple,
concise, but powerful forms of expression.  However, existing
object query languages such as the proposed OQL standard often
require users to navigate through complex networks of objects
to form relationships.  This talk shows how OQL can be extended
by incorporating traversal specifications, which provide a more
flexible means of interrelating objects.  As a traversal
specification is executed, variables are bound to some of the
objects visited.  These variables are then made available to
the rest of OQL.

The extended query language is referred to as Adaptive Query
Language (AQL).  The talk will explain the syntax and semantics
of the core of AQL and discuss possible extensions to AQL. 
A prototype implementation experience, using the Demeter/C++ Tools
and the Texas object-oriented persistent store, will be discussed.
The proposals of several other authors to simplify object navigation
will also be reviewed and compared to AQL.

Thesis committee: Karl Lieberherr (advisor), Betty Salzberg,
  Ed Sciore (Boston College).

Host at Harvard University: Ugo Gagliardi
  This defense takes place in Professor Gagliardi's class on
  object-oriented data bases.

Here is some information about PCTE:


1. Technical Features of PCTE
-----------------------------

PCTE stands for "[a basis for a] Portable Common Tool Environment".

PCTE provides a set of well integrated basic services which form a
foundation for distributed software development environments (SDE).
Systems of that sort are often termed SDE frameworks, or
repositories. PCTE mainly comprises:

- a distributed database management system based on the entity
  relationship model with extensions such as composite objects,
  versions, multiple inheritance, long fields (files), dynamically
  created views, nested transactions etc.

- an execution system which offers all essential features of the
  POSIX model of program execution such as process hierarchies,
  inheritance of open files, process communication via pipes and
  message queues. Tools can be written as shell scripts. A
  notification mechanism allows tools to keep multiple windows
  consistent and supports control integration within the SDE.

- distribution services: the object base and processes are
  transparently distributed; replication of objects is supported,
  schema management is distributed. PCTE is designed for large
  networks of workstations and allows isolated workstations (e.g.
  portable ones) to operate autonomously.

- extensive security features: discretionary and mandatory access
  controls for individual objects, auditing

PCTE is self-referential: types, processes, partitions of the object
base, users, user groups etc. are represented as objects.


2. API vs. kernel vs. SDE
-------------------------

All services described above are accessible via an application
program interface (API). The ECMA and ISO standards of PCTE are
functional specifications of this API. APIs for the host languages C
and Ada are standardised, there is a draft for a C++ API. In order
to make sure that all language-bound specifications are consistent,
there is one language-independent (`abstract') specification of the
PCTE services to which all language-bound specifications refer.

An implementation of one of the APIs must contain a library and
runtime kernel for all operations of this API (except a few
operations which are optional). In addition, any product will
consist of a number of administration tools for installation,
backup etc., a browser, a DDL compiler etc. 

A PCTE-based SDE consists of a PCTE implementation and a set of
tools which are based on the PCTE API and which are integrated via
the PCTE services.

PCTE provides a dedicated framework for distributed data and control
integration in modern I-CASE environments / SDEs. In a groupware
context, PCTE can also provide an excellent technology to implement
process models and enact them in a distributed way leading to a new
generation of highly integrated process centered SDEs.


3. History and Future
---------------------

PCTE originates from an European ESPRIT project (PCTE versions 1.4
(1986) and 1.5 (1988)). It was significantly extended in a NATO
project (PCTE+) and during the ECMA standardisation. In 1994, it has
been adopted as ISO standard IS 13719. The standard consists of
three volumes:

 - language-independent specs 	ISO/IEC 13719-1  (also ECMA-149)
 - C   language binding		ISO/IEC 13719-2  (also ECMA-158)
 - Ada language binding		ISO/IEC 13719-3  (also ECMA-165)

The PCTE specifications are maintained by ISO/IEC JTC1/SC22 WG22 and
ECMA/TC33. There is an OMG-SIG on PCTE. The OMG-SIG, TC33 and WG22
work on additional services for fine-grained data support and CORBA
compliant object-oriented extensions.

PCTE is the result of of hundreds of person-years of effort over ten
years and has matured significantly in this process.


4. Products and Prototypes
--------------------------

Examples of PCTE implementations which are commercially available
today include:

- EDS's Portos runs on Sun's Solaris, DEC's OSF1,VMS, Microsoft's NT,

- Transtar's Emeraude is heterogeneously distributed across
  Sun/Solaris, HP/UX, IBM/AIX, DEC/OSF1, Bull/SCO and PC/Microsoft's
  Windows. e-mail: info@transtar.fr; phone: +33 1 46 94 77 77; fax:
  +33 1 46 94 77 99

PCTE-based I-CASE/SDE products/projects integrating well known CASE
tools include:  ICL(UK)'s ToolPark, NTTdata(Japan)/SMG(USA)'s DATA
Bench, Thomson(France)'s Entreprise, Transtar(France)'s ISD,
Vista(USA)'s PCTE WorkBench.

A research prototype implementation known as H-PCTE is freely
available from the Univ. of Siegen, Germany. H-PCTE implements only
the DBMS of PCTE and has been used to study performance issues and
as a testbed for tool development techniques.  Information:

- e-mail list (pcte@omg.org) with over 300 hundreds people
- ftp server (omg.org) to retrieve electronics copies of specs,
  info, docs.
- PCTE Newsletter (free from PIMB, info from rcochran@catalyst.ie
  fax +353 1 883 0882)
- PCTE Specifications (free from ECMA at helpdesk@ecma.ch, fax +41 22
  786 5231, or from the ftp server) [be warned that the API specs are
  not a tutorial, they are definitely not recommended for beginners]
- OMG/SIG/PCTE and ECMA/TC33 technical working groups  (every 2 months)
- PCTE User Group in North America (NAPUG), Japan (JPUG) and Europe (UG)

Several dozen articles about PCTE and PCTE-based environments have
been published in conferences about software engineering in general
and SDEs; the database literature does not contain much material
about PCTE.
