Course Name:
CA-IDMS for the Application Programmer
Course Number: TT110
Description: This
course focuses on CA-IDMS/DB database concepts and navigation techniques. Lab
exercises will use CA-OLQ to enforce navigation techniques along with coding
examples in COBOL for a batch environment.
Through a set of structured practice sessions, students will practice coding
techniques learned in class.
Topics of discussion
include:
- Introduction to CA-IDMS/DB
- Organization of data
- Data storage
- Set structures
- Data structure diagram
- Database currency
- Preparing for database access
- Verifying database access results
- Retrieving data
- Updating data
- Protecting data integrity
Duration:
3 days
Prerequisites:
Students should have a working knowledge of COBOL, MVS
JCL and TSO.
Target Audience:
Programmers and others who will write or modify
navigational code in the CA-IDMS/DB environment
Objectives:
Upon completion of this course, student will be able
to:
- Describe the characteristics of CA-IDMS/DB and the
effects of programming in that environment
- Identify records, sets and foreign-key relationships
on a data structure diagram
- Recognize record components on a data structure
diagram
- Identify information on a data structure diagram and
indicate importance to a programmer
- Define currency and give examples of how currency is
used in database processing
- Describe the requirements for accessing a database
- Use ERROR-STATUS, IDMS-STATUS & AUTOSTATUS
- Write the code to retrieve and store data
- Explain how the database is protected from
concurrent update or abnormal program termination
- Access CA-IDMS/DB database structures using CA-OLQ
as well as coding DML statements
