Data management with microcontrollers (MCUs) and electronic control units (ECUs) presents challenges related to data volume, quality, integration, security, and compliance, requiring robust strategies and software. Problems due to limited processing power, memory constraints, and the need for efficient storage and retrieval of data make data management tasks especially complex for these devices. In this white paper, we review the important elements of data processing and data management challenges and explain how ITTIA DB tackles each issue and solves the problem for manufacturers that are building embedded systems.
