It’s all about connections
Ready to jump into the weird but useful ways to connect data between IBM® IMS™ databases? And, no, we're not talking about IMS data sharing, but rather, logical relationships.
For example…
What if you have the parts for a bicycle stored in different physical databases. One database (A) has information on the frame parts, and another database (B) has the information for the gears. How can you write one application that finds information on related parts in more than one database? I mean, we don’t have all day for this.
The good news is that IMS applications can find parts that are interrelated. For example, say, a sprocket part number is recorded in database A, and that sprocket attaches to the frame, which is recorded in database B. If you implement logical relationships, the application can find both parts—all without duplicating data!
Who is the course for?
This course describes logical relationships in IMS databases. Logical relationships establish logical access paths between segments that are usually in different databases. The logical path is established through various pointer types that are maintained by DL/I. In this course, you’ll learn how to code the DBDs and PSBs for IMS databases involved in logical relationships, adjust the performance of these databases, and review IMS Monitor reports to see whether the logical relationships are effective.
This is an advanced course for IMS database administrators (DBA) responsible for designing, implementing, maintaining, or tuning IMS databases that use logical relationships.
Learning objectives
After completing this course, you should know how to:
- Code the DBDs and PSBs for IMS databases involved in logical relationships, including those using recursive data structures
- Use IMS utilities to load and reorganize logically related databases
- Choose logical relationship update rules based on application processing requirements
- Identify the DBD coding parameters that are critical to the performance of logically related databases
- Interpret the results of logical relationship implementation choices using the reports provided by the IMS Monitor
If you successfully complete the course, you'll get a digital badge!
You'll need an IBM account to enroll in the course and a Credly account to accept the badge.
