	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.  The latest version is
always posted; the ftp version is never ahead.

There is a WWW version provided by Karl Guggisberg of the Software
Composition Group: http://cuiwww.unige.ch/~scg/FreeDB/

I will post this document about once a year 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?   I have not used any
of these database nor have I used many commercial databases.  I am
not qualified to answer your database questions or able to reccomend
a database for your use.  Please try not to ask.

Thanks,

multiuser:	no
transactions:	no
distributed:	no
query language:	?
description:	A major component of the Datascope Seismic Application
		Package is a relational database system, Datascope. Although
		it is used primarily for seismic applications at the JSPC,
		it is a general purpose database system which can also be
		useful outside the seismic community.  Datascope is a
		relational database system in which tables are represented
		by fixed-format files.  The system provides the standard
		operations on relational database tables: subsets, joins,
		and sorts. And, since the data is typically plain ascii,
		it's also possible to just use standard UNIX tools like
		sed, awk, and vi.  Some features:
		+ It is possible to store ranges as keys and index them
		+ Attributes can have units
		+ Support for foreign keys
		Datascope provides a cheap, easy, fairly intuitive way of 
		moving from the traditional plethora of formats to a better 
		approach which organizes the data, documents it, and 
		provides powerful tools for manipulating it.

		beta.  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

description:	Typhoon is a relational database management system.  It was

		of nice features not found in db_VISTA.
		All relations are defined in a so called Data Definition
		Language (ddl) file.  You define the database relations like
		you would write a C structure with chars, ints, strings,
		multidimensional arrays, nested union and structures, etc. Then
		you define primary, alternate and foreign keys for each
		relation.  The Data Definition Language Processor (ddlp)
		compiles the database defintion into a binary file which
		constitutes the database description. The database relations
		are accessed via C subroutines which manipulate individual
		records within a table.
		- Multiple open database
		- Multi-field keys
		- Nested structures in records
		- Controlled unions
		- Referential integrity
		- Variable length fields
		- Null keys (optional keys in db_VISTA, but easier to use)
		- Dynamic opening and closing of database files

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.

		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)

		The Monet Server runs multiple interpreter threads, which parse

		can runtime be extended with new modules.
		The Monet kernel is designed as a microkernel DBMS. This design
		keeps the code mean and lean. Different users can plug in

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.

		Triton provides for multi-language access and sharing of data,
		dynamic creation of classes (with methods) and objects, special
		support for relations, and special support for triggers. Triton
		uses a client-server architecture with data and methods held in
		the server.
		Triton is written in E, which is a persistent C++. 
		What Triton adds to Exodus is another interface and a lot
		of higher-level functionality.	This includes an Object Manager

robustness:	Until it has a real logging/recovery mechanism,
		I wouldn't advise using it for mission critical

		you will lose. Has a function to flush the
		cache to disk, so you can do explicit checkpoints

description:	GRAS is a database system which has been designed according
		to the requirements resulting from software engineering

		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:	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.

interface to:	Oracle

description:	ciORA is a set of C interface routines to Oracle that are
		modeled after the standard I/O portion of the C library.  ciORA
		presents a familiar interface to an experienced C programmer by
		avoiding the awkward embedding of SQL statements using
		precompilers and the tedium of using low-level OCI calls.
		ciORA eliminates the need for precompilers by supplying an
		interface library providing equivalent functions.  It also
		provides a higher level of abstraction to the functions in the
		Oracle Call Interface (OCI).  ciORA manages (and hides) the
		tedious details necessary when writing programs using OCI by
		replacing the cumbersome Oracle constructs such as logon data
		areas, cursor data areas, and external datatypes, the Oracle
		array interface, bind variables, select-list-items, and the
		like with constructs familiar to a C programmer using the
		standard I/O portion of the C library.	ciORA also provides a
		consistent interface to Oracle errors similar to the convention
		used in C's errno.

description:	AdaSAGE is not a DBMS.
		AdaSAGE is an application development tool that provides
		facilities for creating an application specific relational data

		listening to SQL and responding by executing the requested
		command. Second is issuing SQL to get a foreign system to
		execute some process on your behalf.  In the first case AdaSAGE
		provides both an embedded SQL technology and an interactive SQL
		system adapted to comply with ANSI-SQL DML Level 1. In the
		second case AdaSAGE does not provide any capabilities for
		creating SQL commands, but since AdaSAGE is a set of Ada
		packages there is no reason that a package could not be
		developed to do so.
		The capability to record all transactions and roll forward from

name:		GNUstep Database Library
version:	1.0.0
interface from:	GNUstep
interface to:	Postgres, Sybase, SQL Server
description:	The GNUstep Database Library is a hierarchy of Objective-C
		classes that provide a three-tiered architecture for
		developing database applications.  The three-tier architecture
		is a flexible paradigm for building robust and scalable
		client/server applications; the three tiers refer to the
		database, the Application Objects, and the user interface.
		The separation of the database from the user interface
		through intermediary Application Objects allows the data
		to be distributed appropriately across database servers
		and still have the user interface display data cohesively
		for the end-user.  Business logic, as implemented in the
		Application Objects, provides the mechanism for consistency
		and reusability across all your business applications.

name:		Onyx
version:	2.47
interface from: Onyx 4gl, Tcl, web
interface to:	Ingres89, GAWK, Shql, Yard, Minerva SQL, Postgres4.2, 
		some CDROMs! (German Books in Print)
interfaces:	Onyx uses a OO-Parser to translate SQL to different query
                languages.
                The transaction manager can be accessed by any aplication
                which is able to use pipes or TCP/sockets.
multiuser:	Depends on the engine used.
transactions:	Yes, but no rollback, all transactions are atomic as
		a block, replication of transactions is possible.
distributed:	Yes its possible to connect to any mentioned database
                anywhere in the net.  Replication over mail or tcp is
                posible, and crypted with idea/md5.
query language: SQL + Onyx 4gl + Tcl + "extended" HTML
limits:		Current version uses memory to store active cursors.
                Most people told there is to few documentation.
                GCC > 2.5.8 sometimes makes problems.
robustness:	Onyx is stable, and useable for clients. If you are using a
                stable engine, you'll get a stable applcation. And you can
                exchange engines, when performance or features/bugs are
                required.  The author is selling applications to departments
                of environment in germany, and bookstores.   The author would
		like to have it keep track of his paycheck.
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:		actively developed and supported; current version is stable.

what:		database date manipulation library
version:	1.0
interfaces:	?
access methods: ?
multiuser:	no
transactions:	no
distributed:	no
query language: enhanced SQL2 
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.
