Design Aspects of a Database for Remote Laboratory ManagementThis paper describes the design of a database which is used to manage the remote laboratoryRLab. RLab allows users from all over the world to access a set of real world physical models,to perform experiments by interactively working with them in a realtime environment, and todownload the resulting data to their own computer system for further processing. The onlyrequirement for the user's computer is an internet browser.RLab was originally developed at ***University1***; it uses NI LabVIEW to perform theinterfacing to the real world models, as well as to interact with users and the database. The RLabinfrastructure has been ported to a mechanical laboratory site at ***University2*** during thepast two years and is now used in its engineering curriculum, thereby offering access to somefurther real world models and gaining synergy from an international cooperation.To properly run such remote laboratory several aspects need to be considered. New users needto be registered at the system. The availability of experiments needs to be managed. Forinteractive work with one of the experiments, time slots need to be reserved in advance, and theattempt to access the experiments must be verified against the reservations. The experiments'parameter settings as well as results data must be kept to be retrievable afterwards, etc.. Thispaper collects requirements from a set of use cases around RLab. It then groups therequirements, proposes a data model, and describes the implementation using a relationaldatabase system. Furthermore some issues are discussed when extending the laboratory byfurther models and/or experiments, and the paper explains how this is taken care of by the RLabapproach. These results may help institutions to create an appropriate data managementarchitecture when establishing some own remotely accessible experimentation sites.
