Can MATLAB^® scale up and meet increasingly demanding fleet test data analytics requirements? To assess the capability and limitations, MathWorks developed a big engineering data demonstrator. In this presentation, Arvind summarizes the result of the yearlong research project to implement a vehicle fleet test data analytics system, including interesting insights into automotive engineering data for different use cases. Highlights include reference architectures to integrate MATLAB with commonly used big data technologies for exploring and visualizing data, techniques for online enrichment of test data as they are streamed, and design considerations to allow efficient storage and execution of analytics on large data sets.
