        Catalog of Free Database Systems

This document attemts to catalog databases that are 
available without payment and with source.  

The latest version of the document can be ftp'ed: get
pub/free-databases from ftp.idiom.com.

I will post this document about once a month to comp.databases,
comp.databases.object, comp.answers, and news.answers.  I will 
also post it to other groups somewhat randomly.

Please send additions, corrections, and donations to 
David Muir Sharnoff <free-databases@idiom.com>


I would like user testimonials.  I want to know which databases
are usable and which are trustable!  Is there any database on
this list that I could store payroll records on?

Thanks,

name:           DiamondBase
version:        0.2
interfaces:     C++ library
access methods: b+ tree
multiuser:      Alpha in this version
transactions:   no
distributed:    no
query language: C++ methods
limits:         limits are set at compile time.  The default max records 
                is 21474836.
robustness:     The database engine is quite stable. The multi-user extensions
                are a recent addition and are still considered to be an alpha
                version. The single user version is separate however and
                unaffected.
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. Facilities are now available to access
                generic relations without providing comparison code. It was
                written originally as a replacement for MetalBase which was too
                slow.  DiamondBase is very fast.
announcements:  send mail to Darren Platt to be put on their list
questions:      send mail to Darren Platt
bugs:           send mail to Darren Platt
requires:       C++

robustness:     Very mature technology
description:    This is the database program that was the basis for INGRES
                Corporation.  Obviously, it does not have all the bells 
                and whistles of the current commercial product.  However,
                it is small and fast and it works.
                So called ordered relations are slow and not locked.

description:    MetalBase is a small relational database.  It has all the
                pieces that a relational database should C interface, curses
                interface, report writer, etc.  It does not have design which
                takes advantage of shared memory or the better access methods.
                None of the interfaces are standard, but all of them are easy
                to use.

                Stonebraker at U. C. Berkeley.  To facilitate research
                efforts, a software test-bed was created; this is the
                "Postgres" DBMS software.  The Postgres DBMS is extended
                relational or object oriented, depending on the buzzword du
                jour.  Postgres is relational.  It is highly extensible.  It
                has object oriented features like inheritance.  it has query
                language procedures, rules, updatable views, and more.

distributed:    yes, includes replicated objects
query language: ?
limits:         ?
robustness:     "all reported bugs fixed"
description:    Arjuna is a programming system for reliable distributed
                computing. Arjuna supports nested atomic actions for
                controlling operations on objects (instances of C++ classes),
                which can potentially be persistent. The software available
                includes a C++ stub generator which hides much of the details
                of client-server based programming, plus a system programmer's
                manual containing details of how to install Arjuna and use it

name:           EXODUS Project software
version:        GNU E 2.3.3, Storage Manager (SM) 3.1
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, but not nested.
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.
references:     A bibliography of EXODUS related papers can be obtained from
                the ftp site described below.  Some of the papers are available
                from the ftp server as technical reports, and are marked as
                such in the bibliography.
status:         No longer being developed.  However, the authors are working
                on a new system, SHORE, and will support current Exodus 
                users well enough to keep them going until SHORE is useable.
                GNU E 2.5.8 is in beta and can be ftped.

access methods: ?
multiuser:      yes
transactions:   no
distributed:    no, but maybe later
query language: hypertext-ish X user interface
robustness:     The underlaying store handler (NODE) has been used since '89
                and is quite stable. The system have betweem 20 to 500 users.
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)

                OBST was originally designed to serve as the common persistent
                object store for the tools of an software engineering
                environment.
                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.

description:    Texas is a simple, portable, high-performance persistent store
                for C++ using "pointer swizzling at page fault time" to
                translate persistent addresses to hardware-supported virtual
                addresses.  Texas is built on top of a normal virtual memory,
                and relies on the underlying virtual memory system for
                caching.  Texas is easy to use, and is implemented as a UNIX
                library.  It is small and can be linked into applications.  It
                requires no special operating system privileges, and
                persistence is orthogonal to type---objects may be allocated on
                either a conventional transient heap, or on the persistent
                heap, as desired.  Texas supports simple checkpointing of heap
                data.

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,

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.

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

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.

interfaces:     Virtually none. 
access methods: ?
multiuser:      no
transactions:   no
distributed:    no
query language: Query-by-example object retrieval + some
limits:         The database is memory resident when in use and cannot

robustness:     Operation is fairly stable but by no means for
                mission-critical data.  Mostly useful for experimentation.
description:    MOOD5 is an object-oriented database system written in Prolog.
                Unlike other general purpose OODBS, the system is meant to be
                used by non-programmer end-users with its unified user
                interface named the Object-Editor, or OE, in short. Therefore,
                the program may better be described as an OODB application. It
                is developed for the purpose of exprimenting the power of OODB
                in dealing with complex material data. As a result, it contains
                may novel features which are considered to be necessary to
                support material database practice such as the reasoning for
                data retrieval, the support of literal expressions for physical
                quantities, and so on.  Interest from engineers/scientists who
                are to deal with a bulk of experimental data (not only from
                materials) and programmers in association with them are very
                much appreciated.

                Guarantees recovery from (almost) all application/system crashes
description:    GRAS is a database system which has been designed according
                to the requirements resulting from software engineering
                applications. Software development environments are composed
                of tools which operate on complex, highly structured data.
                In order to model such data in a natural way, we have selected
                attributed graphs as GRAS' underlying data model.
                The current version has programming interfaces for Modula-2 and 
                C and supports:
                - persistent attributed, directed node- and edge-labeled 
                  graphs (including long attributes and indexes)
                - temporary/volatile generic sets, binary relations, and lists,
                - graph modification triggers causing further modifications
                - primitives for version control comprising the capability
                  for efficiently storing graphs as forward/backward deltas 
                - primitives for declaring graph schemes and for incremental
                  evaluation of derived attributes (constraints).
                In additon, there are tools for compressing and displaying 
                graphs.  The GRAS system may be considered to be the core of a
                graph oriented DBMS environment.  The environment is based on a
                VHLL called PROGRESS.  This environment supports: a
                syntax-directed editor for graph schemes, rewrite rules and
                sequences of rules; an incremental consistency checker; an
                incremental compiler&interpreter for PROGRESS; an enhanced
                graph browser

description:    RDB is mostly a set of Perl scripts working as filters, like

name:           The Berkeley DB code
version:        1.79
interfaces:     ndbm, hsearch
access methods: hash, b+tree, recno
multiuser:      no 
transactions:   no 
distributed:    no
query language: none
limits:         can handle large items
robustness:     The db routines are used in some production code so they
                are likely to work reasonably well.
description:    The Berkeley DB Code is a unification of several previous
                interfaces.  It also forms the basis of a unified interface
                to new access methods (b+tree, recno).

description:    Ths is a library that maintains a simple balanced btree index.
                Nothing more is provided than routines to insert, set, find
                (specific, next, and previous), and delete keys. Each key,
                however, has a spare long value that can be used to contain an
                offset to a data file. A library to handle fixed-length records
                based on these pointers should be trivial. (Can you say
                'dBASEIII'?) Another failing of this library is its total
                inability to cope with having several programs modifying
                indices at the same time. (it *CAN*, but I won't vouch for the
                result) The good solutions to that particular problem are OS
                dependent, unfortunately, and I am not a database guru anyhow.

robustness:     The README says that there are bugs.
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.

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.

name:           CB++
version:        0.1
interface from: C/C++
interface to:   SunOS/Oracle (DOS+Windows/Oracle,Gupta, OS/2 Sybase)
description:    CB++ provides a plain C/C++ interface (not embedded) for SQL
                database server access.  It was written in 1989 as a basis for
                storing C++ objects in a relational database.   It is very
                simple to use and makes applications portable among different
                SQL databases.  The library itself is relatively easy to port
                as the database vendor specific code is separated into a single
                C++ class which makes up only a limited part of the library.
                The author supports the current SunOS/Oracle version and
                server ports to other UNIX databases (DOS-, Windows-, OS/2-stuff
                is provided as it is and no longer supported)

version:        3.0
interface from: Unix, Macintosh, MS-DOS, MS-Windows, and Macintosh Hypercard
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.

version:        2.28
interface from: Onyx 4gl, (emacs and smalltalk planned)
interface to:   Ingres89, Informix, GAWK, Shql, Yard (Postgres, OBST planned)
                The informix port is slow and no longer being extended
                because the author feels their support is inadiquat.e
interfaces:     Onyx uses a OO-Parser to access different engines
                The transaction manager can be accessed by any aplication
                which is able to use pipes or TCP/sockets.
multiuser:      Depends on the used engine.
transactions:   Yes, but no rollback, all transactions are atomic as
                a block, replication of transactions is planned for
                one of the next releases.
distributed:    Yes its possible to connect to any mentioned database
                anywhere in the net.  Replication is planned.
query language: SQL + Onyx 4gl (based on Model-View-Controller idea)
limits:         Current version uses memory to store selected data.
robustness:     Onyx is experimental, but useable for clients.  The author is
                supporting himself by writing applications written in Onyx 4GL.
description:    Onyx is a 4gl based on the idea of model view controller. Onyx
                4gl connects to a transaction manager based on a OO-Parser
                generator via a socket.  While the design goal of the protocol
                was to keep it as simple as posible, its a good starting point
                of writing vendor independent database applications.

description:    MultiCal is both a novel approach to supporting multiple
                calendars and internationalization of time constants and a
                query processor prototype that demonstrates this approach.
                MultiCal consists of about 48K source lines of C code; the
                query processor prototype consists of about 63K source lines of
                code.  The documentation consists of fifteen documents,
                comprising some 300 pages of material.
                MultiCal consists of an approach to providing limited
                extensibility for support of multiple calendars and languages
                for temporal support within a database management system
                (DBMS). We have augmented the Structured Query Language (SQL),
                specifically, SQL2, with time values, i.e., temporal
                constants.  Our approach is notable in that we allow many
                different calendars to be used in the database management
                system, and we incorporate only calendar-independent constructs
                into the language. We introduce three new temporal data types.
                New language features are defined for temporal built-in
                functions, special time values, arithmetic expressions
                involving time, temporal predicates, and aggregate functions
                over time. Ten languages are supported.
                To illustrate how an existing DBMS could be augmented to
                support multiple calendars, we provide a prototype DBMS that
                supports the proposed extensions. This prototype consists of
                query analysis and execution components. It eschews traditional
                functionality such as concurrency control and disk access
                methods, as these aspects are not relevant to timestamp
                management.
