Q1Domain Verified
In the context of CouchDB's document model as presented in "The Complete CouchDB Document Model & JSON Design Course 2026," which of the following best describes the primary characteristic of a CouchDB document that enables its flexibility and schema-less nature?
Documents are strictly enforced to conform to a predefined JSON schema, ensuring data consistency across all records.
Documents are inherently relational, with foreign key constraints managed directly within the JSON structure for referential integrity.
Documents are designed to be transactional, with ACID properties guaranteed at the individual document level for immediate consistency.
Documents are immutable and can only be updated by creating entirely new versions, linked via revision history.

Considering the "JSON Design" aspects of "The Complete CouchDB Document Model & JSON Design Course 2026," what is the most significant advantage of denormalizing data within CouchDB documents for read-heavy workloads, as opposed to a normalized approach?
Denormalization reduces disk space usage by eliminating redundant data, leading to faster I/O operations.
Denormalization simplifies document updates by ensuring that all related data resides in a single, easily modifiable structure.
Denormalization minimizes the number of joins required by views, thereby significantly improving query performance for frequent read operations.
Denormalization enhances data integrity by creating multiple copies of the same data, ensuring that at least one copy is always accurate.
Q3Domain Verified
Within the CouchDB core architecture, the concept of "MVCC" (Multi-Version Concurrency Control) is fundamental. How does MVCC, as discussed in "The Complete CouchDB Document Model & JSON Design Course 2026," directly contribute to CouchDB's ability to handle concurrent writes and read operations without explicit locking?
MVCC uses a timestamp-based system to resolve conflicts by discarding older versions of documents in favor of newer ones.
MVCC employs a locking mechanism at the database level to prevent any concurrent access during write operations.
MVCC ensures that each write operation creates a new version of a document, allowing readers to access older, stable versions while writes are in progress.
MVCC allows multiple readers to access a document simultaneously while writers are blocked until the read operation is complete.
