To answer this question, you need to understand the concepts of ADABAS and DDM.
ADABAS is a high-performance database management system commonly used for transactional processing. It stores data in a hierarchical structure and provides fast access and retrieval capabilities.
A Data Definition Module (DDM) is used to define the structure and characteristics of the data stored in an ADABAS database. It specifies the fields, record layouts, and relationships between records.
Now, let's go through each option to understand why it is correct or incorrect:
Option A) True - This option is correct. An ADABAS database can indeed be mapped with more than one DDM. Multiple DDMs can be used to define different views or structures for the same underlying data in the ADABAS database. This allows different applications or users to access the data in different ways without changing the actual data storage.
Option B) False - This option is incorrect. As explained above, an ADABAS database can be mapped with more than one DDM.
The correct answer is A) True. This option is correct because an ADABAS database can indeed be mapped with more than one DDM.
