description: DiamondBase is written entirely in C++, and uses a schema
compiler to generate C++ class defintions for the objects, as
well as some comparison code which is also linked in to the
final executable. There is currently work to eliminate the
dependency on the extra comparison code to permit generic
browsers to operate on it. It was written originally as a
replacement for MetalBase which was too slow. DiamondBase is
very fast.

version: GNU E 2.3.3, Storage Manager (SM) 3.0
interfaces: GNU E, (C++ for direct access to the Storage Manager)
access methods: B+tree and linear-hashing based indexes
multiuser: yes, client-server
transactions: yes
distributed: yes, applications can access multiple servers in a single
transaction. Distributed commits are performed across servers
and clients have access to an interface allowing participation
in distributed commits managed by an external agent.
query language: GNU E -- a persistent programming language based on C++
robustness: High (at least for academic software).
The SM release includes a facility for regression
testing most features, including crash recovery.
description: The EXODUS Storage Manager (SM) is a client-server object
storage system which provides "storage objects" for storing
data, versions of objects, "files" for grouping related storage
objects, and indexes for supporting efficient object access. A
storage object is an uninterpreted container of bytes which can
range in size from a few bytes to hundreds of megabytes. The
Storage Manager provides routines to read, overwrite, and
efficiently grow and shrink objects. In addition, the Storage
Manager provides transactions, lock-based concurrency control,
and log-based recovery.
GNU E is a persistent, object oriented programming language
developed as part of the Exodus project. GNU E extends C++
with the notion of persistent data, program level data objects
that can be transparently used across multiple executions of a
program, or multiple programs, without explicit input and
output operations.

interfaces: emacs-like editor, ?
access methods: ?
multiuser: yes
transactions: ?
distributed: ?
query language: ?
robustness: ?
description: LINCKS is an object-centred multi-user database system
developed for complex information system applications where
editing and browsing of information in the database is of
paramount importance. The focus is on sharing of small
information chunks which combine to make up complex information
objects used by different users for different purposes. The
information chunks are semi-structured in that they contain one
part which is well-structured to facilitate addition of A.I.
processing within the system, and one part which is
unstructured and suitable for management by the user.
Features: shared composite objects, database history,
atlernative views, change collision notification (when more
than one person makes changes to the same composite object)

access methods: ?
multiuser: yes, but writing locks entire tables
transactions: yes
distributed: ?
query language: C++, tcl, graphical object browser
limits: ?
robustness: ?
description: The persistent object management system OBST was developed by
Forschungszentrum Informatik (FZI) as a contribution to the
STONE project. This project (supported by grant no. ITS8902A7
from the BMFT, i.e. the German Ministry for Research) aims at
the development of a software engineering environment for
education purposes and is carried out as a joint project of
nine german universities and research institutions.
An essential feature of STONE is that the object oriented
paradigm is pursued consequently as a key concept. OBST is the
common persistent object store for all tools within the STONE
environment.
OBST provides a rich OO model including multiple inheritance,
generics, overloading, and privacy. The schema definition
language is syntactically similar to C++. It comes with a
library of pre-defined classes like Set<Entity>, and
List<Entity>. New methods can be incrementally loaded at
runtime.

name: William's Object Oriented Database (Wood)
version: 0.6
interfaces: MCL 2.0
access methods: custom
multiuser: no
transactions: no
distributed: no
query language: none. Has BTrees for indexing.
limits: Will slow down when the database size exceeds
256 megabytes. Otherwise, database size limited
by disk size (up to Macintosh limit, which is,
I believe, 4 gigabytes). Object size limited
to 24 megabytes. If you think of a Wood database
as a random access FASL file, you'll have the
right idea.
robustness: Until it has a real logging/recovery mechanism,
I wouldn't advise using it for mission critical
data. Caches pages in memory, so if you crash,
you will lose. Has a function to flush the
cache to disk, so you can do explicit checkpoints
to make it more robust.
description: Wood is a simple persistent store for MCL 2.0.
This is still alpha software. It is incomplete: though you can
save/restore all Lisp objects to/from a file, there is no
transaction/recovery manager and no garbage collector for the
persistent heap. I will not be able to provide much support,
but you get source code.

--------------------------- deductive databases ---------------------------
---------------------------------------------------------------------------
name: Aditi Deductive Database System
version: beta release
interfaces: motif, command line, NU-Prolog
access methods: Base relations contain variable sized records. Base relations
can be indexed with B-trees or multi-level signature files
(superimposed code words) allowing multi-attribute indexing and
querying, or they can be stored as unindexed flat files.
multiuser: yes
transactions: next release
distributed: ?
query language: prolog, graphical (Motif)
limits: ?
robustness: ?
description: Aditi is a multi-user deductive database system. It supports
base relations defined by facts (relations in the sense of
relational databases) and derived relations defined by rules
that specify how to compute new information from old
information. The old information can be from derived relations
as well as base relations; the rules of derived relations may
be recursive. Both base relations and the rules defining
derived relations are stored on disk and are accessed as
required during query evaluation.
ports: SPARC/SunOS, MIPS/IRIX
author: The development of the Aditi system started in 1988 by
Professor Kotagiri Ramamohanarao, and many people have been
involved in its development, in particular Jayen Vaghani, Tim
Leask, Peter Stuckey, John Shepherd, Zoltan Somogyi, James
Harland and David Kemp. The support of Kim Marriott, David

multiuser: When used with Exodus
transactions: When used with Exodus
distributed: ?
query language: Prolog-like with SQL-style extensions; C++ interface
limits: No type checking; only atomic values in persistent relations
robustness: Research software; used for teaching and in research projects,
but some bugs remain
description: The CORAL deductive database/logic programming system was
developed at the University of Wisconsin-Madison. The CORAL
declarative language is based on Horn-clause rules with
extensions like SQL's group-by and aggregation operators, and
uses a Prolog-like syntax. Many evaluation techniques are
supported, including bottom-up fixpoint evaluation and top-down
backtracking. Disk-resident data is supported via an interface
to the Exodus storage manager; however, CORAL can run without
Exodus if disk-resident relations are not required.
A good interface to C++ is provided. Relations defined using
the declarative language can be manipulated from C++ code,
and relations defined using C++ code can be used in declarative
rules. C++ code defining relations can be incrementally loaded.
requires: AT&T C++ 2.0 or later
ports: Decstations, Sun 4, Sparc, HP Snakes
author: The CORAL group consists of R. Ramakrishnan, P. Seshadri,
D. Srivastava and S. Sudarshan. The following people made
important contributions: T. Arora, P. Bothner, V. Karra

description: lq-text is a text retrieval package.
That means you can tell it about lots of files, and later you
can ask it questions about them. The questions have to be:
"which files contain this word?" or "which files contain this
phrase?", but this information turns out to be rather useful.
Lqtext has been designed to be reasonably fast. It uses an
inverted index, which is simply a kind of database. This tends
to be smaller than the size of the data, but more than half as
large. You still need to keep the original data.
Lqtext uses dbm (berkeley db or sdbm) to store its indexes.

name: SMART
version: 11.0
interfaces: terminal, X (slightly oder version), and several
under development including Z39.50
access methods: inverted file search or sequential search
multiuser: yes, but last writer wins when there are update conflicts
distributed: In-house version, to be made public in fall
query language: Natural language
index size: approx 40% of original text.
limits: Can only handle roughly 4 Gbytes of text in
non-distributed version.
robustness: Research tool; parts have been well-tested but others not.
description: SMART is an implementation of the vector-space model of
information retrieval proposed by Salton back in the 60's. The
primary purpose of SMART is to provide a framework in which to
conduct information retrieval research. Standard versions of
indexing, retrieval, and evaluation are provided.
The system is designed to be used for small to medium scale
collections, and offers reasonable speed and support for these
actual applications.
SMART analyses the collection of information and builds
indexes. It can then be used to build natural-language based
information retrieval software. It uses feedback from the
user to tighten its search.
restrictions: Research use only.

access methods: inverted string index
multiuser: read only
distributed: client/server
query language: natural language, boolean, Relevance Feedback
index size: roughtly = data size
limits: "none"
robustness: fairly high
description: There are three main components: WAISINDEX, WAISSERVER, and
WAISSEARCH.
WAISINDEX creates an inverted file index. WAISINDEX includes
filters for a number of common file formats.
WAISSERVER listens for Z39.50 packets and tries to answer
them.
WAISSEARCH is the user agent that talks to WAISSERVERs. There
are several front ends: shell, X, and emacs.

interface to: Unix/Informix, VMS/Oracle
description: DSQL is a simple client/server protocol to support remote
access of SQL databases. DSQL was designed in response to a
perceived need at Genentech to provide graphical front-ends on
Macintosh computers to Informix relational databases running on
Unix servers. DSQL version 3 is distributed with 2 server
implementations and four client library implementations. The
API for the client libraries has been standardized, and the
client code is divided into portable and architecture-specific
portions.
