Software Design Concepts for Archiving and Retrieving Control System Data

PDF Version Also Available for Download.

Description

To develop and operate the control system effectively at the Thomas Jefferson National Accelerator Facility, users require the ability to diagnose its behavior not only in real-time, but also in retrospect. The new Jefferson Lab data logging system provides an acquisition and storage component capable of archiving enough data to provide suitable context for such analyses. In addition, it provides an extraction and presentation-facility which efficiently fulfills requests for both raw and processed data. This paper discusses several technologies and design methodologies which contribute to the system's overall utility. The Application Programming Interface (API) which developers use to access the ... continued below

Description

To develop and operate the control system effectively at the Thomas Jefferson National Accelerator Facility, users require the ability to diagnose its behavior not only in real-time, but also in retrospect. The new Jefferson Lab data logging system provides an acquisition and storage component capable of archiving enough data to provide suitable context for such analyses. In addition, it provides an extraction and presentation-facility which efficiently fulfills requests for both raw and processed data. This paper discusses several technologies and design methodologies which contribute to the system's overall utility. The Application Programming Interface (API) which developers use to access the data derives from a view of the storage system as a specialized relational database. An object-oriented and compartmental design contributes to its portability at several levels, and the use of CORBA facilitates interaction between distributed components in an industry-standard fashion. This work was supported by the U.S. DOE contract No. DE-AC05-84ER40150
