	The electron stretcher facility ELSA provides a beam of unpolarized and polarized electrons of up to 3.2 GeV energy to external hadron physics experiments. Its in house developed distributed computer control system is able to provide real time beam diagnostics as well as steering tasks in one homogeneous environment. Recently it was ported from HP-UX running on three HP workstations to a single Linux personal computer. This upgrade to powerful PC hardware opened up the way for the development of a new archive engine with a noSQL database backend based on Hyptertable. The system is capable of recording every parameter change at any given time. Beside the visualization in a newly developed graphical history data browser, the data can be exported to several programs - for example a diff-like tool to compare and recall settings of the accelerator. This contribution will give details on recent improvements of the control system and the setup of the history storage engine.

The electron stretcher facility ELSA provides a beam of unpolarized and polarized electrons of up to 3.2 GeV energy to external hadron physics experiments. Its in house developed distributed computer control system is able to provide real time beam diagnostics as well as steering tasks in one homogeneous environment. Recently it was ported from HP-UX running on three HP workstations to a single Linux personal computer. This upgrade to powerful PC hardware opened up the way for the development of a new archive engine with a noSQL database backend based on Hyptertable. The system is capable of recording every parameter change at any given time. Beside the visualization in a newly developed graphical history data browser, the data can be exported to several programs - for example a diff-like tool to compare and recall settings of the accelerator. This contribution will give details on recent improvements of the control system and the setup of the history storage engine.
