- D Support for complex data types like XML and JSON
Reveal correct answer
Correct answer: B
A. Relational databases in Microsoft Azure typically adhere to the ACID properties, which ensure that database transactions are processed reliably and consistently. These properties include Atomicity, Consistency, Isolation, and Durability, which are essential for maintaining data integrity and reliability.
B. Flexible schema refers to the ability to easily modify the structure of the database schema without affecting the existing data. Relational databases in Microsoft Azure typically have a fixed schema that enforces data consistency and integrity, making it more challenging to restructure data on the fly.
C. Data integrity is a crucial aspect of relational databases, and it is enforced through keys and constraints. Keys, such as primary and foreign keys, ensure data relationships are maintained accurately, while constraints, like unique and check constraints, enforce data validation rules to maintain data quality and consistency.
D. Relational databases in Microsoft Azure often support complex data types like XML and JSON, allowing users to store and manipulate data in various formats. This feature enables flexibility in handling diverse data structures within the database system.
