Section 1: Key Points to Know

Anchor: #i1021328

Identifying Characteristics

The TRM User must identify characteristics of the data features within TRM and apply those characteristics to each individual feature in a data matrix. This chapter describes the ADABAS Matrices that contain the system-required information you need to gather in order to update the system successfully.

Anchor: #i1021338

Defined Characteristics

The Adaptable Data Base (ADABAS) matrices provide information to assist any user in selecting values, and entering and retrieving data from TRM:
