cego
| Pop | 680.02 |
|---|---|
| Vit | 471.50 |
Cego implements a relational and transactional database system with support for the SQL query language. The current release contains the most common database features for basic table manipulation and data retrieval. Indexes, foreign keys, views, and stored procedures are also implemented. Future releases (2.0 and above) will support a multi-node database concept with log file shipping for an automatic database application failover.

CloverETL
| Pop | 489.51 |
|---|---|
| Vit | 142.08 |
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
| Pop | 375.15 |
|---|---|
| Vit | 76.71 |
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
| Pop | 927.21 |
|---|---|
| Vit | 85.68 |
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
| Pop | 138.19 |
|---|---|
| Vit | 49.36 |
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".

MUSCLE
| Pop | 611.77 |
|---|---|
| Vit | 130.23 |
MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.

H2 Database Engine
| Pop | 507.46 |
|---|---|
| Vit | 68.45 |
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.

Database Independent Abstraction Layer for C
| Pop | 585.49 |
|---|---|
| Vit | 29.20 |
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.

hamsterdb Embedded Storage
| Pop | 345.68 |
|---|---|
| Vit | 37.82 |
hamsterdb Embedded Storage is an embedded database engine written in ANSI-C. It includes B+Trees with variable length keys and records. It supports in-memory databases and endian-independent files, database cursors, multiple databases in one file, "record number" databases, and duplicate keys. hamsterdb is very fast and highly configurable. It compiles and runs on Unix platforms, Linux, Microsoft Windows, and Windows CE.

MetaModel
| Pop | 215.18 |
|---|---|
| Vit | 23.82 |
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.
