ODS (Open Data Services) focuses on the persistent storage and retrieval of testing data. The standard is primarily used to set up a test data management system on top of test systems that produce measured or calculated data from testing activities. Tool components of a complex testing system can store data or retrieve data as needed for proper operation of tests or for test data post-processing and evaluation. A typical scenario for ODS in the automotive industry is the use of a central ODS server, which handles all testing data produced by vehicle test beds. The major strength of ODS as compared to non-standardized data storage solutions is that data access is independent of the IT architecture and that the data model of the database is highly adaptable yet still well-defined for different application scenarios. Despite this flexibility, clients can query the data from the database and still correctly interpret the meaning of the data. This is achieved by various means through the standard.
ODS servers act as data fusion centers of data from different test beds and measurement devices from different vendors. Data can be accessed independently of their origin via the same methods and interfaces. This even extends to mass-data stored in external files (ASAM MDF), where the DB only holds descriptive meta data a pointer to that external storage location. The same API methods are used for DB-internal measurement data access as well as to external data access, so that users have completely transparent access to the data. Furthermore, ODS servers are scalable, which allow to extend the data models and add more clients to the overall tool chain without having to setup a new server for every extension.
