KInterbasDB is a Python extension package that implements Python Database API 2.0-compliant support for the open source relational database Firebird and some versions of its proprietary cousin Borland Interbase. In addition to the minimal feature set of the standard Python DB API, KInterbasDB also exposes nearly the entire native client API of the database engine.
Daffodil DB is a SQL-99 specification compliant, lightweight, Java-based relational database engine (RDBMS). It supports almost all constructs of SQL 99 (including triggers, views, constraints, UDT, stored procedures, etc.), supports distributed transactions (XA), provides a complete JDBC 3.0 driver (including support for optional features like save points, rowsets, UDT, XA, connection pooling, etc.), and can run in embedded or server mode. It can be included as a jar file in any Java application. Daffodil DB includes Daffodil DB Browser, a GUI-based database management tool that can be used to carry out all database operations such as creating a database, creating database objects, executing SQL statements, and manipulating data, browser database objects, etc.
Sesame is an Open Source RDF Schema-based repository and querying facility. It is a scalable, modular architecture for persistent storage and querying of RDF and RDF Schema. It supports two query languages (SPARQL and SeRQL), and can use main memory or PostgreSQL, MySQL and Oracle 9i databases for storage.
SPTK (Simply Powerful Toolkit) is a cross-platform toolkit that provides a set of C++ classes for fast and easy application development. It provides GUI components that use FLTK, and features database support with seamless connection to GUI components. There are drivers for use of SQLite and PostgreSQL directly, as well as support for other database engines through UnixODBC. SPTK includes many classes for working with strings, dynamic arrays, and maps, and is faster and has a smaller footprint than STL. It also supports reading, writing, and creating Excel 7 files, high-level GUI components with dataset support, support for automatic layouts, and support for Aspell.
The Easysoft ODBC-JDBC Gateway allows ODBC applications to be used with JDBC databases. It is a fully functional ODBC 3.5 driver that allows you to access any JDBC data source from any ODBC-compatible application. All leading Java databases are supported, including JDataStore, Cloudscape, PointBase, FirstSQL, McKoi, and HSQL. It is compatible with unixODBC, the Linux and Unix driver manager.
Active Record connects business objects and database tables to create a persistable domain model where logic and data is presented in one wrapping. It’s an implementation of the object-relational mapping (ORM) pattern in which an object that wraps a row in a database table or view, encapsulates the database access, and adds domain logic on that data.
