Enterprise Data Warehouse
Architecture, Features, Integrations, Costs
Since 2005, ScienceSoft provides businesses from 30+ industries with scalable EDW solutions for efficient data consolidation and enterprise-wide analytics.
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. Enterprise data warehouses integrate with a data lake, ML and BI software.
To enable answering both enterprise-level and department-specific questions, EDW ingests data from all corporate business-critical software and external data sources, including:

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. Below, ScienceSoft's experts provide components of EDW architecture that are common for our projects:
- 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 EDWs, due to their scalability, use ELT (extract, load, transform), which means that the transformation step is performed after data loading into the EDWH.
- 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 EDW and maintains it further on.
- Cloud-hosted – a company deploys an EDW 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.
On-premises
Pros:
- 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 EDW is located can effectively access all the data stored in the data warehouse without dependence on the internet connection.
Cloud
Pros:
- Scalability. The inherent agility of cloud data warehouses allows upscaling and downscaling with no impact on 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 too.
Hybrid
Pros:
- Cloud flexibility. Meeting storage and compute requirements with near-unlimited cloud resources.
- Data compliance. Ensuring sensitive data is stored within the environment which fully meets data compliance standards.

To build a future-proof EDW with all the necessary features, it’s crucial to create data models that not only reflect current business operations but can be easily modified in response to your business growth. Keeping data models’ flexibility in mind, ScienceSoft’s solution architects always work together with seasoned industry experts to envisage potential business changes and efficiently organize enterprise data access, collection, storage, analysis, security, etc.
Key EDW Integrations
Ensures cost-efficient storage of raw data in its initial format. We often implement tiered raw data storage for further cost optimization, e.g., keeping frequently accessed data in a high-performing, costlier tier and storing less ‘popular’ data in a lower-cost, lower-performance tier.
Self-service analytics software
Your team members can generate the reports they need within minutes instead of waiting days for IT or data analysts to create them. Having access to accurate and up-to-date data at the required angle, they can make informed decisions.
Machine learning software
Your data scientists get access to vast amounts of reliable data to build highly accurate models for forecasts, process automation, smart recommendations, and more.

The major factors that influence the cost of the enterprise data warehouse implementation project are:
- The number and diversity of data sources, the complexity of data flows.
- The volume of the data to be ingested and stored by the solution.
- An EDW’s performance, availability, scalability requirements.
- The target data quality thresholds (consistency, accuracy, completeness, etc.) to be achieved within the data transformation processes.
- The data sensitivity and data security requirements.
Based on ScienceSoft’s experience in EDW software implementation, the approximate timeframes for the EDW implementation project are from 3 to 12 months, and the cost of an enterprise data warehouse implementation project may vary as follows:

Enterprise Data Warehouse Benefits
Cross-department collaboration
With all business users having access to a single point of truth, EDW eliminates data silos, enables easy and secure data sharing, and guarantees that all users make decisions based on common information.
Saved time of IT staff and data analysts
Thanks to self-service BI capabilities and data management automation, an EDW minimizes the involvement of IT teams in BI tasks and significantly reduces the manual work of analytics teams.
A 360-degree view
The role of an enterprise warehouse in data mining is essential. An EDW consolidates and stores massive data from various sources, allowing companies to get a comprehensive view of their business at the current point, from the perspective of the past years, and at an angle of intelligent predictions and what-if scenarios.
A solid foundation for implementing AI/ML analytics
Providing vast amounts of multi-source, high-quality data, an EDW makes it possible to train precise AI/ML models that enable accurate predictions, smart recommendations, and business process automation.

How do you ensure compliance with the regulatory standards our EDW requires?
We have in-house compliance experts that can guarantee your solution fully adheres to any required global and local regulations, including HIPAA, GDPR, FDA, MDR, PCI DSS, ADHICS, and more.
What is the difference between an enterprise DWH and a DWH?
The difference between an EDW and a data warehouse is in scope. An enterprise data warehouse supports company-wide decision-making and deals with data from the entire organization, including all the internal and external sources, departments, and business units. A DWH can be limited to handling department-specific analytics.
