C EXECUTIVE COURSE OUTLINE

JMI Software Systems offers a standard training course for C EXECUTIVE and related products. In addition to a comprehensive 2 day presentation of the products, a system design session is offered. During this optional 1-to-3 day extension, fundamentals of data flow design, structured design, and related methods of software design are presented, followed by a design (or design review) of the customer's application as it would be implemented with C EXECUTIVE. Data flow diagrams, state tables, and pseudo-code are used to document the design.

Please refer to the description of our design method which has examples of data flow diagrams, pseudo-code, and sample code.

The application design course extension has been used by customers designing color printers, multi-function FAX/laser printers, FAA radar systems, laboratory instruments, communication systems, process control systems, routers, and a wide variety of other real-time embedded applications. Please refer to one customer's comments on this course.

The class can be taught either at JMI's offices or at the customer's site. There is no per-student fee; there is only a standard fee for the instructor and any travel expenses.

Note: depending on class experience and customer needs, certain sections can be deleted and other sections expanded.
