What Is an Enterprise Data Warehouse: Core Concepts

An enterprise data warehouse (EDW) is a data management solution that centralizes company-wide data in a highly structured format ready for analytics querying and reporting. Its implementation costs can range from $70,000 for the most basic solution to $400,000 to cover the needs of a midsize enterprise. The costs of an EDWH for a large enterprise comprising multiple data sources and advanced analytics capabilities will be higher. An enterprise data warehouse integrates with a data lake, ML and BI software.

To enable answering both enterprise-level and department-specific questions, the enterprise data warehouse ingests data from all corporate business-critical software and external data sources, including:

  • Enterprise resource planning (ERP) system.
  • Customer relationship management (CRM) system.
  • Accounting software.
  • Talent management system.
  • Business process management (BPM) system.
  • Intranet.
  • The company’s website.
  • IoT device management system.
  • Publicly available datasets for machine learning, etc.

Data Warehouse vs Enterprise Data Warehouse


  • Stores data for particular business units
  • Answers department-specific questions

Enterprise DWH

  • Consolidates and stores data for all business units
  • Answers enterprise-level and department-specific questions

Enterprise Data Warehouse Architecture

An enterprise data warehouse is a core element of a BI solution, which is structured in accordance with the particular data management and analytics needs a company pursues. Here, you may see common architectural components of the solutions that ScienceSoft delivers:

Enterprise data warehouse (EDW) architecture components

  • A data source layer - an enterprise data warehouse pulls data from apps’ databases, enterprise systems (e.g., CRM, ERP, document management software, HRM) and external sources (e.g., social media, government reports, chosen stock market trackers).
  • A staging area - an intermediate storage area of temporary nature for data processing under the extract, transform and load (ETL) process. ETL consolidates data from multiple sources and transforms it into a modeled format suitable for storing in the enterprise DWH. Cloud-based enterprise data warehouses, due to their scalability, use ELT (extract, load, transform), which means that the transformation step is performed after data loading into an enterprise data warehouse.
  • Data storage layer - centralized storage where data is made accessible for analytics (querying, reporting) and sharing.
  • Analytics and BI - data in the enterprise data warehouse can be queried via OLAP tools, data mining tools, reporting and visualization tools.

Enterprise Data Warehouse Types

There are three deployment environment types for data warehousing solutions:

  • On-premises – a company purchases all required hardware and software to build and deploy an enterprise data warehouse and maintains it further on.
  • Cloud-hosted – a company deploys an enterprise data warehouse in the cloud, eliminating the need to purchase and maintain hardware and software.
  • Hybrid – a company augments an on-premises enterprise data warehouse with a cloud-hosted repository.



  • Full control over the enterprise data warehouse. In case of a failure, an in-house IT team has direct access to the DWH’s problem area for hardware and software tuning. Moreover, data security remains strictly under the in-house IT team’s control.
  • Full compliance with the required data standards. Data security compliance is easier to achieve with on-premises enterprise DWHs.
  • Availability. Business users from a facility where the enterprise data warehouse is located can effectively access all the data stored in the data warehouse without the dependence on the internet connection.

See the points of caution


  • Full responsibility. Together with the control of the on-premises enterprise data warehouse, a company is fully responsible for its implementation and maintenance.
  • Complexity of agile scaling. To comply with the increased storage or compute requirements, you need to purchase new hardware, which may result in the need to tune or replace current software.




  • Scalability. The inherent agility of cloud data warehouses allows upscaling and downscaling with no impact on the enterprise data warehouse performance.
  • Reduced costs. There are no hardware-related costs (hardware acquisition, deployment, maintenance, administration, etc.). And if you opt for Enterprise Data Warehouse as a Service, all software acquisition and maintenance costs are eliminated either.

See the points of caution


  • Data compliance. Although most cloud providers have security features difficult for attackers to penetrate, some industry standards and regulations (FDA, HIPAA, etc.) still require sensitive data to be stored on-premises.
  • The risk of budget overruns. Unexpectedly increased query volumes, which require additional compute/storage resources, lead to overspending if no controlling or limiting the cloud resources is set up.




  • Cloud flexibility. Meeting storage and compute requirements with the near-unlimited cloud resources.
  • Data compliance. Ensuring sensitive data is stored within the environment which fully meets data compliance standards.

See the points of caution


  • DWH costs. The company has to cover the maintenance costs and operating expenses of the on-premises DWH system while still paying the subscription fee for cloud DWH services.
