The document outlines various types of data warehousing architecture, including single-tier, two-tier, three-tier, and multi-tier architectures. It describes each architecture's functionality and components, emphasizing operational differences such as client-server communication and data processing layers. The text also hints at training opportunities for those interested in becoming data analysts.

1. TYPES OF DATA WAREHOUSING
ARCHITECTURE

2. DATA WAREHOUSE
• Data Warehouse also known as Enterprise
Data Warehouse (EDW) is a system used for
reporting and data analysis.
• They store current and historical data.

3. The data warehouse architecture has many types.
Single Tier
Two Tier
Three Tier
Multi Tier
ARCHITECTURE…..

4. SINGLE-TIER ARCHITECTURE
 Processing of data takes
place in the main frame
only.
 Various devices are
connected to it just for
the purpose of display.
 They access data through
dumb terminals.

5. TWO-TIER ARCHITECTURE
• It is a client-Server
Architecture.
• There is a direct
communication
between the client
and the server.
• They are tightly
coupled and thus 2-
tier application is
faster.

6. THREE-TIER ARCHITECTURE
• The Client layer is used for the
design purpose.
Ex. Designing a form with
text, label etc.
• The Business layer is the
interface between the Client and
the Data Access Layer and makes
their communication faster.
• Actual database comes in the
picture.
 Contains methods to
connect with the database.
 Performs manipulations
with the database like inserting,
updating, deleting.
Client Layer
Business Layer Data Layer

7. MULTI-TIER ARCHITECTURE

8. Get yourself trained with Data Warehousing and
become a data analyst…..
