Oracle NoSQL Database Cloud Service supports operations on data based on keys. Which of the following best describes how data is primarily accessed and retrieved within this model?
A.
Data is accessed using structured query language (SQL) with joins and complex filtering conditions.
B.
Data is retrieved by traversing relationships between interconnected nodes in a graph structure.
C.
Data is primarily accessed using the unique key associated with the desired data item.
D.
Data is searched based on the content of the values using full-text indexing and complex search queries.
E.
Data is accessed through a predefined schema that dictates how data is organized and queried.
Oracle NoSQL Database Cloud Service follows akey-value data model.
Data is accessed directly using aunique key, which is highly efficient for lookups.
The value associated with the key can be simple or complex (e.g., JSON objects).
Provides fast read and write operations.
Why the other options are incorrect:
A. SQL with joins:Typical of relational databases, not NoSQL.
B. Graph traversal:Relevant to graph databases, not key-value stores.
D. Full-text indexing:Not the primary access method in key-value databases.
E. Predefined schema:NoSQL databases generally supportschema-lessdata storage.
