Companies increasingly adopt cloud-based technologies for streamlined data collection, reporting, and analysis in today’s business landscape. Data Warehousing is pivotal in business intelligence, helping organizations to enhance performance. It’s crucial to grasp the data repository concept and its significance in the global marketplace. 

Data and analytics are now indispensable assets for any business striving to maintain competitiveness. When monitoring business performance, decision-makers depend on reports, dashboards, and analytics tools to extract insights from data sourced from various channels.

What is a Data Warehouse? What are the Key Features

A data warehouse collects an organization’s data and information from internal and external sources. Information is regularly extracted from internal applications like sales, marketing, finance, customer-facing applications, and external partner programs. This data is utilized for analysis by data scientists to make predictions.

Now, what exactly is a data warehouse? Initially, it is an extensive repository of current and historical information strategically crafted to enhance organizational performance.

The key features of a data warehouse include the following. 

1. Subject-Oriented: The database focuses on specific topics, providing more insightful information on the subject rather than consisting of the entire business process. Topics may include marketing, promotions, glossary, etc. For instance, when analyzing a company’s sales data, a dedicated sales database offers crucial insights like ‘Who was the best customer last year?’ or ‘Who could be the best customer next year?’

2. Integrated: The data repository consolidates information from diverse sources into a standardized format. Data is stored securely and uniformly, ensuring a universally accepted naming, format, and coding repository. This integration facilitates effective data analysis.

3. Non-Volatile: Data remains unchanged, strictly read-only once stored in the database. Previous data is preserved even when new data is added. This feature enables the analysis of historical changes and events.

4. Time-Variant: Data stored in the database is time-dependent, either explicitly or implicitly. An example of time variance in the Data Warehouse is reflected in the primary key, which must incorporate a time factor such as day, week, or month.

Data Warehouse Architecture

Data Warehouse Architecture refers to the design of an organization’s framework for collecting and storing data. Given the need to process, cleanse, and organize data for usability, data warehouse design focuses on identifying the most efficient way to transform raw information into a comprehensible system that yields valuable Business Intelligence (BI) insights.

When constructing a data warehouse, three primary architecture types are considered, each with merits and drawbacks. The Single-tier warehouse architecture aims to create a compact dataset and minimize stored data. While effectively reducing redundancies, it may not suit organizations with substantial data requirements and multiple streams.

Two-tier storage systems physically separate available resources from the facility itself. This enhances data processing and organization efficiency but needs more flexibility and requires a minimum number of end-users.

The Three-tier, most widely adopted data warehouse architecture establishes a structured flow for actionable insights from raw data sets. The bottom tier houses the database server, including data cleaning and transformation back-end tools. 

The second tier utilizes Online Analytical Processing (OLAP) as an intermediary between end-users and the warehouse. OLAP can interact with relational and multidimensional databases, enabling additional data collection based on broader parameters. 

The top tier serves as the front end of the company’s overall business analysis system, where developers can use queries, data visualizations, and analytics software to interact with results.
