Alzabo is a two-fold program. Its first function is as a data modelling tool. Through either a schema creation interface or a custom Perl program, it allows a programmer to create a set of schema, table, column, etc. objects that represent a data model. Alzabo is also capable of reverse engineering an existing data model. Its second function is as a RDBMS-to-object mapping system. Once you have created a schema, you can use Alzabo classes to access its data. These classes offer a high-level interface to common operations such as SQL SELECT, INSERT, DELETE, and UPDATE commands.
Oracletool is an interactive, Web-based application for Oracle Database administration. The advantage of Oracletool over non-Web-based tools is that nothing needs to be installed on the client-side machine or in your databases. All you need to use Oracletool, once installed, is a Web browser.
MyJgui is a GUI (graphical user interface) for MySQL. It aims to be easy to use for new users as well as experts. You can store multiple connections that can be used simultaneously. Stored passwords are encrypted using symmetric encryption. Underlying databases and tables are displayed in a tree structure with the connections being the first level nodes. MyJgui is capable of easy data manipulation through a grid. It has a unique feature of bookmarking parametrical queries (sqlmarks). The documentation (user guide) is quite comprehensive and kept up-to-date.

Groonga is a fast and accurate full text search engine based on an inverted index. Newly registered document instantly appears in search results, and updates are allowed without read locks. These characteristics result in superior performance for real-time applications. It is also a column-oriented database management system (DBMS). Compared with well-known row-oriented systems, such as MySQL and PostgreSQL, column-oriented systems are more suited for aggregate queries.
SymmetricDS provides file and database synchronization with support for multi-master replication, filtered synchronization, and transformation across the network in a heterogeneous environment. It supports multiple subscribers with one-direction or bi-directional, asynchronous data replication. It uses Web and database technologies to replicate data as a scheduled or near-realtime operation. The software has been designed to scale for a large number of nodes, work across low-bandwidth connections, and withstand periods of network outage. It works with most operating systems, file systems, and databases, including Oracle, MySQL, MariaDB, PostgreSQL, MS SQL Server (including Azure), IBM DB2, H2, HSQLDB, Derby, Firebird, Interbase, Informix, Greenplum, SQLite (including Android), Sybase ASE, and Sybase ASA (SQL Anywhere) databases.
