HiBase: A Persistent Functional Programming Environment

News

Jun 25 2009: Nokia-Siemens Networks, the current copyright holder of HiBase, has double-licensed the code written by employees of Helsinki University of Technology in the HiBase-project under the MIT-license in addition to GPL (v2). The same hereby is granted to all later additions to the source code.

Jul 24 2002: An update on the status of reimplementation work.

Nov 16 2001: Ville Laurikari has completed his Master's Thesis and released a related tagged regexp matching package. Kenneth Oksanen has released an extended version of his Licentiate's Thesis, and made a bugfix release hibase-0.1.3.

Spring 2001: Nokia Networks aborted the project. We have no subsequent information regarding possible use, maintainance or further development of HiBase at Nokia. Contrary to earlier promises, Nokia refused to grant us a sufficient license to the code and inventions developed at HUT so that we could find alternative funding to develop HiBase to its conclusion.

However, former members of the HUT team continue to develop and rewrite the software on their leasure time towards a GPL'd public release. Very old preliminary versions have already been published on our download page.

Introduction

The goal of the HiBase project was to develop a high-performance database programming environment with challenging additional features required in telecom environments.  These features include high performance, heterogeneous transaction load, complex dynamic database schemes, multi-dimensional indexing, main-memory databases with real-time response, and very high availability ensured by replication and instantaneous takeover.
