E(Extracted): Data is extracted from External data source. 3-Tier Data Warehouse Architecture Data ware house adopt a three tier architecture. Data Warehouse Three Tier Architecture. 2 The bottom tier is a warehouse database server that is almost always a relational database system. T(Transform): Data is transformed into the standard format. The middle tier is an OLAP server which is typically implemented using either (1) a Relational OLAP (ROLAP) model, (2) a Multidimensional OLAP (MOLAP) model. It is usually the relational database (RDBMS) system. The bottom tier of the architecture is the data warehouse database server.

INTRODUCTION:- Data warehousing is an algorithm and a tool to collect the data from different sources and Data Warehouse to store it in a single repository to facilitate the decision-making process. In three-tier architecture for data warehouse,_____ contain the data and the software for data acquisition in one tier,the data warehouse is another tier,and the third tier includes the decision support and the client. Cost-ineffective; Three-Tier Architecture: Three-tier architecture typically comprise a presentation tier, a business or data access tier, and a data tier. The two-tier data warehouse architecture Short Answer . In this acticl I am going to explain Data warehouse three tier architucture. Database ServerThis DBMS architecture contains an Application layer between the user and the DBMS, which is responsible for communicating the user's request to the DBMS system and send the response from the DBMS to the user. It actually stores the meta data and the actual data gets stored in the data marts. The middle tier is the application layer giving an abstracted view of the database. The following concepts highlight some of the established ideas and design principles used for building traditional data warehouses. The three-tier architecture consists of the source layer (containing multiple source system), the reconciled layer and the data warehouse layer (containing both data warehouses and data marts).
