JSlovo: database management system for free dictionaries

Version 1.0, February 2005 (c) copyright S.Chekanov (chekanov@sdf.lonestar.org)

jSlovo is a fast database engine and a GUI written in JAVA. It should work on any OS where JAVA is installed. With jSlovo you can create a file-based database from a text file and then use it to search for particular words. It was designed mainly for free dictionaries. The dictionaries can be taken from http://www.dicts.info/ or any other place. The only requirement is that the text file should be in UTF-8 format, with one translation per line, and definitions should be separated by tabulator or "|".

Here are the main features of JSlovo:

Databases from the text files can be created using JSlovo GUI
It is very fast. It uses two-level indexing algorithm;
It can scan any large number of databases. The size of the databases are not limited. All databases are disk based;
Unlike to other JAVA databases (Derby, HSQL), the memory usage of JAVA VM is constant and does not depend on the number of booted databases;
Created databases are very compact (databases are zipped);
Based on UTF-8 encoding;
One can use HTML tags in the text files for created databases;
During the search, HTML files are created with the results of the search. Each definition can further be searched;
Search can be done using substrings.

You will see that this dictionary is now ready for use. Using JSlovo and text files from http://www.dicts.info/, you can create as many dictionaries as you like. They all will be put automatically to the same directory "dbase" and will be ready for use once you have created dictionaries using JSlovo.
