Architect is an open source data analysis workbench, available through Open Analytics:
Data scientists manage rich data sources, build statistical models and communicate findings. They work at the intersection of computer science and statistics and often rely on a multitude of tools to keep on top.
Architect provides an Eclipse-based workbench in which data scientists can get their job done, in other words, an integrated development environment (IDE) targeted specifically at data scientists.
Architect installers for Windows 32-bit and 64-bit and for Mac OS X are freely available from the Open Analytics downloads page. Packages for GNU/Linux (Debian and Ubuntu) are available from the Open Analytics repository at deb.openanalytics.eu and sources are on Github.
