goto a list of sys_db_object, query on name, 'is one of', and put in the list, review the 'Extends table' value.

Hi @pranjalsrvs,

 

correct answer is d) CMDB

 

Because base table is OOTB table with no parents, and cmdb table is extended with cmdb_ci  and others.

cmdb_rel_ci is abotu relationships and ecmdb with the "e" in the beginning doesn't exist.

 

Similarly, it's for [task[ table.

 

Refer to this:

Hi @pranjalsrvs ,

 

Correct answer is:- Base table for CMDB is cmdb but for CI Class Manager [CMDB Hierarchy - Base table is cmdb_ci]

 

  • cmdb_ci:

This table represents the core Configuration Item (CI) and stores the basic attributes of all CIs within the CMDB. 

  • Other options:
    • cmdb_rel_ci: This table stores relationships between CIs, referencing the cmdb_ci table to establish connections. 
    • ECMDB/Ecmdb_rel_ci/Ecmdb_ci: These terms are not typically considered as the base table of the CMDB hierarchy. ECMDB might refer to an extended CMDB or a specific implementation of it, and the other related tables likely deal with specific relationships within the extended CMDB. 

Key point: The cmdb_ci table is the foundational table for all other CI-related data in the CMDB.
