CloverETL is Java-based tool/framework for data integration and creation of data transformations. It is component based and follows the concept of transformation graphs which consist of individual nodes/components performing simple (or complex) operations on data. Any transformation can be defined as a set of interconnected nodes through which data flows. CloverETL can be used as a standalone application or be embedded into a larger project.
deltasql is a tool to synchronize databases with source code, which helps to keep database evolution under control. While developing mid-sized or big applications, developers make changes to the data model that go along with changes to the source code. From time to time, branches of source code are done to stabilize the code that will go to production. A sort of data model branch is also needed. deltasql provides a simple way to collect all scripts that change the data model and means to handle data model branches. The deltasql server runs on Apache and is backed by MySQL.
SymmetricDS is Web-enabled, database independent, data synchronization/replication software. It uses Web and database technologies to replicate tables between relational databases in near real time. The software was designed to scale for a large number of databases, work across low-bandwidth connections, and withstand periods of network outage. It includes support for Oracle, MySQL, PostgreSQL, H2, HSQLDB, Derby, MS SQL Server, Firebird, IBM DB2, Informix, Interbase, and Greenplum databases.
GT.M is a high end platform for developing transaction processing database applications. Individual database files in the terabyte range are supported; a logical database can consist of many files. It provides full support for ACID transactions using a Software Transaction Memory (STM) programming model and optimistic concurrency control. The GT.M data model is hierarchical associative memory (i.e. multi-dimensional arrays) that imposes no restriction on the data types of the indexes or content, nor any restriction on the schema is that imposed by the application. Such databases are also referred to as "document oriented", "schemaless", or "schema-free".
H2 is an SQL database engine written in Java that implements the JDBC API. Embedded, server, and clustering modes are available. A browser based console application is included. The database has strong security features. Disk based and in-memory databases and tables are supported.
libdbi implements a database-independent abstraction layer in C, similar to the DBI/DBD layer in Perl. Writing one generic set of code, programmers can leverage the power of multiple databases and multiple simultaneous database connections by using this framework. The plugin architecture allows for new database drivers to be easily added by a third party with flexible licensing.
The eobjects.org MetaModel is a project created for maximum reuse of a SQL-compliant domain model of the database domain. The MetaModel is a model that contains classes that represent the structure of a database (schemas, tables, column, relationships) and interaction with the database (queries) in a SQL/LINQ-like way. In short, it is a model for modelling data in databases and other datastores. With MetaModel you can query different datastores like databases, CSV files, Excel spreadsheets, MS Access files, and XML files using the same approach and the same domain model.
StelsMDB is a MDB JDBC type 4 driver that allows you to perform SQL queries and other JDBC operations on Microsoft Access database (versions 2000, 2002, 2003, and 2007) files. The driver is completely platform-independent and does not require installing additional client or server software to provide access to MDB files. It can be effectively used to create, process, and export Microsoft Access databases in your Java applications. It supports most keywords of ANSI SQL'92, supports inner and outer table joins, supports CREATE, INSERT, UPDATE, and DELETE statements, supports transactions, and supports aggregate, numeric, string, conversion, and user-defined SQL functions.
SymmetricDS Pro is software for data replication, change data capture, and data transformation in a heterogeneous enterprise environment. Performance and scalability allow it to replicate thousands of databases asynchronously in near real time. With flexible configuration and powerful scripting and programming interfaces, it can be extended to meet a range of requirements. Based on the popular open source version of SymmetricDS, the Pro edition enhances the experience with a click-through installer, Web management console, and production support.
GeoServer is a software server that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. GeoServer is the reference implementation of the Open Geospatial Consortium (OGC) Web Feature Service (WFS) and Web Coverage Service (WCS) standards, as well as a high performance certified compliant Web Map Service (WMS). GeoServer forms a core component of the Geospatial Web.
