Which of the following is a characteristic feature of a Relational Database Management System (RDBM

One of the fundamental characteristics of a Relational Database Management System (RDBMS) is its ability to enforce data integrity through the use of constraints such as primary keys, which ensure that each row is uniquely identified, and foreign keys, which maintain referential integrity between related tables. This feature helps prevent data anomalies and ensures consistency within the database. Why Other Options are Wrong: a) RDBMS is designed for structured data, not unstructured data. c) RDBMS uses a relational model, not a hierarchical one. d) RDBMS is designed to support multi-user environments with concurrent access. e) RDBMS strictly follows ACID (Atomicity, Consistency, Isolation, Durability) properties, which guarantee reliable transactions.
