Information Modeling with STEP and EXPRESS

2 day class, contact STEP Tools for the current tuition cost

The EXPRESS information modeling language is used inside and outside of STEP to describe object-oriented information models for Concurrent Engineering, Mechanical and Electrical Products, Asset Management, Laboratory Analysis, Geological Modeling and other applications. This course introduces the student to information modeling, the EXPRESS language and its companion EXPRESS-G. Demonstrations and class exercises are included in the course.

Workshop Topics

  • Information Modeling
  • EXPRESS Basics
  • EXPRESS-G Basics
  • STEP usage of EXPRESS
  • Advanced Concepts & XML
  • Software Tools

Who Should Attend

Information managers, software engineers and programming professionals who need to develop or interpret information models for object-oriented applications.

All classes are held at STEP Tools, Inc. in Troy, New York.
