Mainframe Fundamentals for
Distributed and Web Programmers
| Duration: 1 day |
| Participants: People who wish to become IBM z/OS mainframe application programmers or support personnel, or people who are working in a client/server or Enterprise web environment who need to interface with mainframe computer software and data and need to know the basics of mainframe computer processing. |
|
Objectives:
Upon successful completion of this course you will be able to:
- Describe the concept of application programming. - Explain the functionality of different hardware components of a computer and the different sizes and capabilities of different hardware platforms. - Discuss the purpose of an operating system and ways one communicates with an operating system. - List the various subsystems of the z/OS operating system. - Describe how data is stored and encoded, and contrast mainframe and PC encoding and storage techniques. - Describe networks and their features. - Contrast computer jargon on different platforms environment in which they work. |
| Overview: This lecture/discussion course is designed to introduce mainframe computer application programming concepts to participants interested in becoming a programmer or programming support person, and for C/S and web developers who need to interface with mainframe software and data. This course focuses on mainframe architecture and data and is very helpful to developers who need to develop a greater understanding of the computing environment in which they work. |
| Prerequisites: No knowledge of programming is assumed. |
| Format: Lecture and discussion course. Questions are encouraged. |
