Final answer:
Non-relational databases do not use database-mapping and normalization like relational databases.
Step-by-step explanation:
Non-relational databases
Non-relational databases, also known as NoSQL databases, use a different approach to storing and retrieving data compared to relational databases.
Database-mapping
In non-relational databases, the concept of database-mapping is not used as data is not stored in tables with pre-defined relations. Instead, data is stored in various formats like key-value pairs, documents, or graphs.
Normalization
Normalization is a process used in relational databases to minimize data redundancy and ensure data integrity. However, non-relational databases do not follow a strict normalization process as they prioritize scalability and performance over strict data consistency.
