System Architecture

MotorData system is designed as an online service, accessible from anywhere in the world 24/7. Special client-side software is used to connect to MotorData database and display all the information in a user-friendly format.

Such an approach ensures that our customers receive up-to-date and complete data without constant client-side updates. It also allows access to the exact piece of information that the customer needs to solve a problem. Diagram node highlighting, colored wire traces on the interactive diagrams, rich hyper-text capabilities (easy transitions from one component to another) makes the problem analysis and solution smooth and effective. The system is tailored to minimize delays and traffic volume while transferring data via Internet. Our case studies show stable operation even with slow Internet access, such as GPRS mobile connection.
