Databases for Db2 is an IBM Cloud database service that supports both relational and non-relational

data querying.

IBM Cloud Databases for Db2: Db2 on IBM Cloud is a managed database service that supports both

relational and non-relational models. It provides JSON and SQL querying capabilities, allowing users

to store and retrieve data in a flexible manner. This makes it capable of handling structured, semi-

structured, and unstructured data, thus supporting both relational and non-relational data formats.

Support for Multiple Data Types: Db2's multi-model database capabilities enable the execution of

SQL queries on relational data and the storage/retrieval of JSON documents, effectively allowing it to

function in both relational and non-relational scenarios.

Reference from IBM Cloud Professional Architect Materials:

According to IBM's documentation on IBM Cloud Databases for Db2, it supports a broad range of

workloads and use cases, including transactional (relational) and operational (non-relational)

workloads, making it suitable for both SQL and NoSQL data models.

The other options are incorrect because:

A . Databases for Redis is a key-value store optimized for in-memory data.

C . Databases for PostgreSQL is strictly a relational database.

D . Databases for etcd is a key-value store primarily used for configuration management.
