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.
DBeaver is a universal database manager and SQL Client. It supports MySQL, PostgreSQL, Oracle, DB2, MSSQL, Sybase, Mimer, HSQLDB, SQLite, Derby, and any database that has a JDBC driver. It is a GUI program that allows you to view the structure of a database, execute SQL queries and scripts, browse and export table data, handle BLOB/CLOB values, modify database meta objects, etc. It has a native UI (provided by the Eclipse SWT library), great performance, and relatively low memory consumption.
websqlclient (WSQLC or wiskl) is a lightweight HTTP server which allows an end user to access JDBC data sources via automatically-generated data entry screens. It is designed to be used with standard Web browsers and wireless tablet PCs, and is highly configurable. It can connect to any JDBC data source. Its main purpose is to provide rapid data-model-driven development. The websqlclient data entry forms are generated by querying the database system table information, but can be configured manually. websqlclient includes a database-agnostic data loading utility (SQLLoader), a data unloading tool (SQLExport), and SQL scripting capabilities.
