A widely used standard for the persistent storage of measurement data is ASAM ODS. Automotive manufacturers and suppliers use it primarily to set up comprehensive data management solutions for different measurement systems and data formats. In this way, they make test data usable in the long-term, regardless of the tools of individual vendors. Generally in such solutions, the search for certain measurements bases on descriptive information, the so-called metadata.
To gain more information from the existing measurement channels, Peak Solution has developed the Peak Advanced Search.

With Peak (Test) Data Transfer Tool (short: PeakDTT), Peak Solution offers a generic command line tool that convert measurement data and metadata of certain data sources into a defined data target within the scope of different processes. Currently the tool provides plugins for the following data formats: ATF, ATFx, ODS, MDF4 and ISOMME. Of course, users can add additional plugins for application-specific source and target formats at any time if required.
By means of configurable mechanisms it is e.g. possible to map the different data structures of the connected source systems to a uniform ODS application model. In this way, test field manager can easily implement a central and standardized “measurement data hub” for several measuring systems of different vendors. The following figure gives an overview:

Using the Peak ODS server, various ODS clients can subsequently access the measurement data uniformly and interpret it correctly. In addition, the Peak (Test) Data Transfer Tool can be used to exchange application models between different ODS applications via ATFx.
Peak Solution provides an extension for Peak ODS Server (PODS), which is suited for accessing and processing measurement data stored in Parquet files. In its latest technology proposal for Big Data, ASAM has recommended this format as appropriate for storing mass data.

Many automotive manufacturers and suppliers all over the world have used the Peak ODS Server for many years as a powerful backbone for ODS-based applications. Now, Peak Solution has released version 3.0 of the software. By that, Peak ODS Server also supports the current ASAM Standard ODS 6.0. This provides, among other things, an optimized API for accessing measurement data as well as a notification service for the synchronization of distributed ODS servers.

The efficient performance of tests plays a decisive role in vehicle development. Test stand automation and virtualization are important for this, but they are not longer enough. Especially in global acting enterprises a powerful management system is required that overcomes rigid departmental boundaries and gets the complexity of the test processes under control.

The openMDM Eclipse Working Group has published version 0.7 of the openMDM 5 framework. openMDM 5 is a kit of software components, which can be used to compose web-based applications for measurement data management systems. The source code as well as an installation guide for a demo environment are available as download under the so-called MDM|BL project, hosted by the Eclipse Foundation.
