Cloudscape

IBM Cloudscape (now open sourced as Apache_Software_Foundation Derby) is a pure, open source-based Java programming language Relational Database Management System that can be embedded in Java programs and used for online transaction processing (OLTP). A platform-independent, small-footprint (2MB) database, Cloudscape integrates tightly with any Java-based solution.

= Derby Technologies =

Derby Embedded Database Engine

The core of the technology, Derbys database engine is a full functioned relational embedded database engine. JDBC and SQL are the programming APIs.

Derby Network Server

The Derby network server increases the reach of the Derby database engine by providing traditional client server functionality. The network server allows clients to connect over TCP/IP using the standard DRDA protocol. The network server allows the Derby engine to support networked JDBC, ODBC/CLI, Perl and PHP.

Database Utilities

  • ij -- a tool that allows SQL scripts to be executed against any JDBC database.
  • dblook -- Schema extraction tool for a Derby database.
  • sysinfo -- Utility to display version numbers and class path.

    • = History =

    Cloudscape Inc, an Oakland, California, California start-up, was founded in 1996 to develop Java Database technology. The first release of the database engine, then called JBMS, was in 1997. Subsequently the product was renamed Cloudscape and releases were made about every six months. In 1999 Informix Software, Inc., acquired Cloudscape, Inc. In 2001 IBM acquired the database assets of Informix Software, including Cloudscape. The database engine was re-branded to IBM Cloudscape and releases continued, mainly focussing on embedded use with IBM s Java products and middleware. In August 2004 IBM contributed the code to the Apache Software Foundation as Derby, an incubator project sponsored by the Apache DB project.
