An Introduction to Data Warehousing

The data warehouse is a unified repository that stores data (both structured and unstructured) from different sources and provides businesses with centralized access to data. Unlike operational databases that are designed for transaction processing, data warehouses are mainly optimized for querying and analysis.

By providing a consolidated view of an organization’s data, it enables decision-makers to access and analyze historical data to uncover hidden patterns and behavioral insights. This information enables enterprises to optimize their operational strategies to drive growth and boost ROI. According to Gartner, 91 percent of companies that adopted data warehousing solutions have reported improved decision-making capabilities. This clearly indicates the tangible benefits of incorporating data warehousing as part of the BI strategy.

The Core Components of a Data Warehouse

There are several crucial components of data warehousing that play a critical role in data management and processing. Let us delve into the key components of data warehousing and their significance for business intelligence.

1. Extract, Transform, Load (ETL)

The ETL process, as the term suggests, extracts data from multiple sources, transforms it into the desired format and loads it into a data warehouse. This process cleanses, normalizes and aggregates data to enhance quality and consistency.

2. Data Storage

Data warehouses are designed to store enormous volumes of data in the most efficient, presentable, and easily retrievable manner. For this reason, they use specialized storage architectures like massively parallel processing (MPP) or columnar databases. Furthermore, these systems enable query performance optimization, enabling users to access data faster and more efficiently.

3. Metadata Management

In data warehousing, metadata is the data that describes content, structure, or the relationship between different data types stored within the warehouse. It is often described as ‘data about data’ and forms a quintessential part of data warehousing or data management. The use of metadata ensures that users are able to understand the structure and lineage of data stored within a warehouse.

4. Data Mart

A data mart is an important part of the data warehouse that is designed to store and retrieve client-facing data and analyze department-specific information more efficiently. A data warehouse generally comprises multiple data marts that store department-specific data and provide seamless access to this data, whenever required.

5. Data Warehouse Access Tools

A series of access tools are required to easily retrieve data from a warehouse and use it for business intelligence. This includes query and reporting tools, data mining tools, application development tools and online analytical processing (OLAP) tools and data visualization tools.
