Cross-site utilization of test resources, integrated test request and order processes, global access to test data and big (test) data solutions: These are the topics that are the focus of Peak Solution at Automotive Testing Expo Europe 2017 in Stuttgart (20th to 22nd of June).

The openMDM® EWG (Eclipse Working Group) published a web-based prototype client for navigating and searching in test data in the middle of 2016. In December 2016, Peak Solution began to expand this client on behalf of BMW. The goal is to prepare openMDM® 5 for productive use at BMW Group.
In order to be able to find measurement data quickly even after a long time and to interpret and compare it unambiguously for different purposes, it is necessary to precisely document the context in which they were created. With the help of templates, this can be standardized across team and department boundaries.
Measurement data must be quickly retrievable, comparable and interpretable for different purposes and by different persons even after a long time. Companies can only achieve this by precisely documenting under which conditions (= context) the respective measurement data have been created. Conclusion 1: Transparency on test data becomes problematic, if measurement files are stored on the hard disk of a local computer or server just based on individually selected names without a detailed description.
That´s why the market offers a whole series of software tools with which this file-based storage of measurement data can be better organized.
An important function of openMDM® 5 is the full-text search. It allows test engineers to find measurements based on arbitrary search terms and without knowing the exact location.
When choosing a suitable platform, Peak Solution investigated the two servers SolR and ElasticSearch in detail. This article gives a brief overview on how their features match with the requirements of the openMDM® 5 Eclipse Working Group and what recommendation was given.
Looking for an efficient solution for the management of measurement data in motor development, DAF Trucks N.V. has decided to count on openMDM®. The decisive factor was, that openMDM® is an open, manufacturer-independent software platform that enables its users to implement domain specific measurement data management solutions economically and in a forward-compatible way. In addition, the software is based on the ODS standard (Open Data Service) of the ASAM (Association for Standardisation of Automation and Measuring Systems, http://www.asam.net). The generic data model of ODS provides DAF Trucks with a reliable and at the same time flexibly expandable basis for the long-term usability and comparability of test data.
More and more car manufacturers and suppliers require solutions for enterprise-wide, multi-side test data management. Against this background, Peak Solution has investigated different ways to implement a global access to test data based on openMDM® 4.
During the investigation, Peak ODS Server was used for data storage in “mixed mode”. This means metadata (= test and measurement descriptions) is stored in an Oracle database, while mass data is stored in binary files (ASAM MDF) on a file share. The database holds in the course of this a pointer to the external storage location.
