	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 idiom.berkeley.ca.us.

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.berkeley.ca.us>


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,

-Dave

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

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.

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,

query language:	C++, tcl, graphical object browser
limits:		4 GB per container, 2^32 containers
robustness:	OBST is quite stable since the start of '93. Releases were
		made to enhance the coding quality rather than to add new
		features. There are somewhere between 50 and 500 users.
description:	The persistent object management system OBST was developed by
		Forschungszentrum Informatik (FZI) as a contribution to the
		STONE project (supported by grant no. ITS8902A7 from the BMFT,
		i.e. the German Ministry for Research).
		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.

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.

		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.

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.

name:		GRAS (GRAph-oriented database System)
version:	5.90/9 [[6.0 alpha]]
interfaces:	Navigational programming interfaces for C and Modula-2
access methods:	tries fro database pages, static hashing within pages
multiuser:	Very restricted single writer/multiple reader access
		[[6.0: shared read/write access with locks on a per-session, 
		transaction, or operation basis]]
transactions:	yes; based on backwards logs.  Checkpoints allow roll-back (and
		roll-forward) to a previous state.  
distributed:	no.  [[6.0: Multiclient/multiserver architecture]]
query language:	PROGRES (PROgrammed Graph Rewriting Systems; a language released
		separately)
limits:		2**16 nodes per database and 2**16 databases per multi-database
		[[6.0: 2**32 nodes]]
robustness:	Has been successfully used as the underlying database for
		a number of research prototypes and one commercial product.
		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

		result) The good solutions to that particular problem are OS
		dependent, unfortunately, and I am not a database guru anyhow.

name:		Onyx
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.
status:		experimental; actively developed and supported.

access methods:	?
multiuser:	no
transactions:	no
distributed:	no
query language:	enhanced SQL2 
index size:	?
limits:		?
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.
