Free embedded database software for linux

Web Reference Database is a bibliographic manager that can import and export references in various formats (including BibTeX, Endnote, MODS XML, and OpenOffice).
It can make formatted lists of citations in HTML, RTF, PDF, or LaTeX, and offers powerful searching, rich metadata, and RSS support
Enhancements:
- This release offers major function enhancements and bugfixes.
- Batch import from various bibliographic formats (including BibTeX, Endnote, RIS, ISI, and MODS XML) is now supported, as is import from a PubMed ID.
- An OpenDocument spreadsheet for use with OpenOffice.org can be exported, and formatted citation lists can be generated as HTML, RTF, PDF, or LaTeX. An SRU/W service and support for unAPI, OpenURL, and COinS metadata have been added.
- These allow the data to be used by the next generation of bibliographic clients.
- A new command line client is also included.

MP3DB2 is a collection of bash scripts for keeping track of large MP3 collections. It will retrieve song information from the filenames and ID3 tags of a directory or CD of MP3s and store them in a local database.
This program is a complete rewrite of my MP3 database version 1. Version 1 only stored the data that was present in the filenames while version 2 actually retrieves information from the ID3 tags of each MP3.
Please note that as of this version the database format is NOT considered carved in stone. I have already added a few fields mid-development and this will continue for a while if I think the format can be made better. See the changelog for a list of changes to the database format since V2.0.
Enhancements:
- mp3dupe: now just displays the name of the directory we are checking not the full path in the host filesystem.

MP3-Database project is a tool to organize your MP3 collection. If you insert a CD with MP3 files in your CDROM drive, MP3DB can read all ID3 tags of the MP3 files.
With this information MP3DB creates a database which can be searched for a specific song, artist, or CD.
A GUI makes it easy to use the program. Any title found in the database can easily be added to a playlist or can instantly be played by XMMS.
Main features:
- MySQL (Is needed as database backend)
- Perl5
- Perl Modules:
- Tk
- Tk-MesgBox
- Tk-LabFrame
- Tk-Pane
- DBI
- MP3-Info
- Msql-Mysql-modules
- To play MP3 files the MP3 player XMMS should be installed on your system. MP3-Database can easily be adapted to other MP3 players
Enhancements:
- NEW Data Structure: The MySQL database is much more complex than before. I used 3 Tables for Artists, Albums and Titles to store the data. This ensures that I have no redundancies in the tables. This has also enabled me to store additional fields in the database (for example the date of birth of an artist, or the release year of an album).
- NEW Temporary Database: I added some tables to store all new artists, albums and titles in a temporary database. This enables the user to check the new entries before adding them to the permanent database.
- NEW FEATURES: Additional Artist and Album information can be stored in the database, MP3DB can now create a random playlist and a playlist with the top 20 MP3 titles, MP3DB can show you a statistic how many artists, albums and titles are stored in the database.

Mckoi SQL Database is a full featured SQL-92 relational database management system written in Java.

The software can operate as either a dedicated multi-client, multi-threaded database server, or can be used as an embedded database inside a Java application.

The engine is designed to be easy to use and maintain and versatile for sophisticated database development tasks. The software provides a JDBC 2.0 driver.

To use Mckoi SQL Database, you will need a JavaTM runtime environment version 1.2 or greater. Sun provides Java runtimes for Win32, Solaris and Linux from their website at http://www.javasoft.com/j2se/. IBM also provides various Java runtimes for a number of platforms at http://www.ibm.com/java/jdk/download/.

When Java has been installed on your system, unpack the mckoi distribution file to a directory in your file system. Then you are ready to create a database and develop your database application.

Creating A Database

Before you can begin development of your database application, you will need to create and configure a blank database. The database configuration file describes all of the configurable properties of the database (details of the database configuration file are covered in the next section). The software ships with a default configuration that looks for a database at path ./data in your filesystem.

To create a database using the default configuration with an admin username of admin_user and password aupass00, go to a prompt, change to the Mckoi Database distribution directory and type:

java -jar mckoidb.jar -create "admin_user" "aupass00"

We do not advise using either this username or password in a production system. The user created here has full control over every aspect of the database so choose a username / password carefully.

When the command has completed, a sub-directory called data will have been generated. This directory is used to store data from the database. A sub-directory called log is also generated which stores debugging and query log information.

Database Configuration

When you run the mckoidb.jar package, it looks for a file named db.conf in the current directory. This file contains a number of variables that determine where the database looks for information, as well as other user-definable properties. The configuration file can be renamed and copied to a different location. If you change the configuration file location, you must supply the location when you run the database;

java -jar mckoidb.jar -conf [location of conf file] .....

You can edit the configuration file with a text editor. The default configuration file that ships with the software contains extensive comments on what each variable does.

Java Embedded Python embeds CPython in Java. It is safe to use in a heavily threaded environment, it is quite fast and its stability is a main feature and goal.
Main features:
- Using the native Python interpreter may mean a massive speed improvement over Java-based languages.
- Python is mature so authors neednt fear the interpreter will suddenly change widely-used features.
- Access to the high quality Python modules, both native and Python-based.
- Compilers and assorted Python tools are as mature as the language.
- Python is an ideal language for your business logic. It is easy to learn, eminently readable and generally immune to programming gotchas.
Patches, comments and other help is greatly appreciated. If you need help, post to the SourceForge mailing list or forums. Please include code snippets for the most accurate response.
