Data warehousing architecture refers to the design and structure used to store, manage, and analyze large volumes of data in a data warehouse. It is typically composed of a central repository (the data warehouse) that consolidates data from multiple sources, which then undergoes ETL (Extract, Transform, Load) processes before being made available for business intelligence (BI) analysis. The architecture of a data warehouse defines how the data is stored, processed, and accessed.

### Single-tier Architecture
The single-tier architecture is the simplest form, where all data resides in one location. In this model, the data warehouse and the database are typically __________ _______ _______ ___ ___ _____ __________ ________ _______ ______ _____ ___.
