Open Source Java Database Management Systems (DBMS)

DataCleaner is a data quality analysis application and a solution platform for DQ solutions. It's core is a strong data profiling engine, which is extensible and thereby adds data cleansing, transformations, enrichment, deduplication, matching and merging.

Most people are not familiar with command mode. However, there is only command mode in the world of Hadoop and HBase. For the reason above, we are focusing on developing a set of tools, “HBase Client”, which can be used more easily and having a more friendly interface.

A relational database management system, based on the principles laid down in the book "Databases, Types, and The Relational Model: The Third Manifesto" by C. J. Date and Hugh Darwen.

In Memory Database Management System - with SQL and JDBC interface, entirely written in Java

GEBORA is an administrative tool for the Oracle Relational Database Management System. It's an OpenSource alternative to TOAD. Current version has syntax highlight, schema browser, pl/sql viewer and runner and many other features.

Objectwiz is a an administration tools for JEE 6 applications. Once Objectwiz is installed (one jar and two xhtml files) in the application, administrator can perform the following operations: - display all objects of a particular entity bean, - create/edit entity beans objects, - call methods from the session beans, - launch EJBQL query

addressdb is a graphic front end for an SQLite database. Typically the database may be an address book. addressdb incorporates flexible field searches based on SQlite's native comparison operators and word and regular expression searches. Records may be exported as pdf files with flexible formats (eg address labels) and as text files (eg comma separated values - csv) also with flexible formatting. csv files may be used as backup and to transfer data between databases; addressdb can create a database from a csv file. Database fields and output formats are specified through a text configuration file which may refer to more than one database and include several output formats. Fields may be edited on output (eg commas replaced by linefeeds or the case changed)

Provides a no-shrills interaction to generate SQL queries based on arbitrary basic inputs such as CSV. After extracting, just double click on the CSV2SQL.jar file and choose a CSV file to generate SQL out of. Output should show on the next screen. That's it!

Tracks project details using a variety of data options. Primarily designed to contain and organize software requirements in a multi-project, multi-user, environment using a networked SQL compliant database management system while tracking changes.

TreeBASE is a database and web front end that stores phylogenetic trees and the data matrices used to generate them. The current iteration comprises a complete rewrite of the schema and web layer, and will include a web services layer.

This application assists DB2 users while writing commands, proposing options and parameters or, completing words.

UI To the Hadoop HBase Project

English Developed with the aim of helping teachers from different areas to create automated tests that are unique for each student. EasyQuizzer stores all questions in a database management system. Subsequently, an exam is set up with the desired items. The program will then run randomization algorithms that will shuffle both the questions and the alternatives so that there are no two identical exams. Portuguese-Brazil Desenvolvido com o intuito de auxiliar professores a criar provas únicas para cada aluno. O EasyQuizzer armazena todos os seus dados em um Sistema Gerenciadorde de Bancos de Dados, a saber, o Postgres. O programa executa algoritmos de randomização de alternativas certas e erradas por questão, além de embaralhar questões e alternativas evitando que existam duas provas com o mesmo conjunto de alternativas. O usuário pode especificar o numero de provas que deseja gerar, lembrando que a quantidade de alternativas determina o número máximo de provas únicas.
