Understanding Data Warehouse Architecture

Data warehouse architecture is fundamentally structured to enable efficient storage, retrieval, and management of large volumes of data for analysis and reporting. This involves specialized database management systems that are designed to handle analytical queries.

Analyzing Options

1. DBMS (Database Management System): While data warehouses use DBMS, not all DBMS are designed for data warehousing purposes.
2. SQL Server: This is a specific relational database management system developed by Microsoft, not a general representation of data warehouse architecture.
3. Sybase: Similar to SQL Server, this is also a specific brand of database management software.
4. RDBMS (Relational Database Management System): This is a category of database management systems that is based on the relational model introduced by E.F. Codd. Data warehouses often utilize RDBMS due to their ability to manage and analyze data in a structured way.

Conclusion

Considering the definitions and applications of each option, the most appropriate choice that describes the fundamental architecture of a data warehouse is d. RDBMS.

Final Answer
