rasdaman

Compare

Claimed by rasdaman Analyzed 11 days ago

rasdaman is the pioneer Array DBMS enabling Big Data Analytics on massive n-D arrays ("datacubes") such as spatio-temporal sensor, image, simulation, and statistics data. Its declarative query language extends SQL with high-level array operators. Frontends supported include python, R, GDAL, QGIS ... [More] , OpenLayers, NASA WorldWind, and many more. Client-side parts are LGPL for free use of rasdaman in open and closed applications; the server itself (a separate process) is GPL implementing the paradigm of "life is a give and take". rasdaman has been released into OS by rasdaman GmbH and is now co-led by Jacobs U, the makers of several Big Data standards: ISO Array SQL, OGC WCS and WCPS; rasdaman is official OGC and INSPIRE WCS Reference Implementation and part of OSGeo Live (live.osgeo.org).

NARS2000

Compare

  Analyzed 11 days ago

The first NARS (Nested Arrays Research System) was designed and implemented in the early 1980s as a testbed for new ideas in APL, principally with nested arrays. A quarter of a century later, it's time to try again. The goal of this effort, as with the last one, is to foster new ideas about the ... [More] language and its implementation. Language ideas include new functions, operators, and datatypes. To aid in getting your ideas into an implementation, there will be a mechanism for telling NARS that a user-defined APL function represents a new primitive function, operator, or datatype. In order to experiment with your ideas for new extensions, all you need to know is how to write APL programs. [Less]

Kona is an open-source implementation of the K programming language (K3.2). If you're new to APL, you probably want this project. The K language was originally designed by Arthur Whitney and Kx Systems. It is an ASCII-based array language and a precursor to Kx's KDB, KDB+, and Q. Kona is unaffiliated with Kx.
