Fundamentals of Database Management Systems Quiz

Challenges in building a DBMS include data security, data integrity, concurrency control, data recovery, query optimization, and efficient storage and retrieval of data.

The three-schema architecture consists of an external schema, a conceptual schema, and an internal schema. The external schema describes the part of the database that is relevant to individual users. The conceptual schema defines the logical structure of the entire database. The internal schema describes the physical storage structure of the database.

The various components of a DBMS include a query processor, transaction manager, storage manager, database engine, data definition language (DDL), data manipulation language (DML), and data dictionary.
