Discover key concepts and the architecture behind a logical data warehouse. Learn the difference with traditional data warehouses.

In this post, we’ll explain what a logical data warehouse is and how it can help simplify the management process when dealing with large amounts of structured and unstructured data. We’ll also discuss key points such as scalability, flexibility, cost savings, integration benefits, and more. So if you’re ready to learn all that’s necessary when considering a logical data warehouse solution – don’t miss this infographic with insights from S2E!

What is a Logical Data Warehouse?

Logical Data Warehouses (LDW) allow organizations to break free from traditional data warehousing approaches and access an array of sources, such as relational databases, Hadoop-LIKE clusters, or NoSQL databases in real-time. 

This virtual layer abstracts physical storage to enable direct integration without the need for ETL. Through SQL interfaces, REST APIs, or web portals users have flexible options to analyze their data using visual tools like Tableau QlikView, etc.  Furthermore, they may also include cloud services such as Salesforce Google Analytics & Twitter into this infrastructure.

Check out the infographic below to discover how S2E developed a Logical Data Warehouse and how they applied it successfully in a project for Hippocrates Holding!

Logical Data Warehouse vs Traditional Data Warehouse

In the world of data warehousing, a traditional approach involves a lengthy process of data extraction, transformation, and loading into a central repository. While this approach still holds value, it can be time-consuming and resource-intensive. Enter, the LDW – a flexible, virtual alternative to traditional data warehousing.

Here are the key differences:

Data Integration – data is integrated virtually, granting access directly from its source, sans ETL processes

Data Structure – data is flexible in its organization, allowing for more dynamic querying and analysis than traditional schemas

Data Storage – data can be stored across a variety of sources including databases, Hadoop-LIKE clusters, and cloud-based services

Data Processing – batch processing gives way to real-time or near-real-time processing, supporting timely and accurate data analysis

Data Access – exceeds traditional data warehousing, providing a user-friendly variety of interfaces and tools for querying and analysis.

But be aware, while the LDW offers greater agility and a faster response time, implementing one requires advanced technical skills and is more complex than traditional approaches.
