The Gist of Data Warehouse (DWH) Implementation

Data warehouse implementation implies developing and deploying a data warehouse to gather and structure company’s data for analytical querying and reporting.

Key 8 steps to data warehouse implementation

  1. Determine DWH viability.
  2. Discover data needs.
  3. Conceptualize your DWH and select the optimal tech stack.
  4. Plan the project.
  5. Design the data warehouse.
  6. Develop and stabilize the system.
  7. Introduce the software to end users.
  8. Monitor and improve.
  • Time: From 6-9 months
  • Cost: Starts from $70,000. You can get a tailored ballpark quote for your case in our free cost calculator.
  • Team: A PM, a BA, a DWH system analyst, DWH solution architect, data engineer, QA and DevOps engineers.

For 18 years, ScienceSoft has been designing and implementing efficient data warehouses that serve a solid foundation for robust BI solutions.

Data Warehouse Implementation Trends

Recently, we’ve defined 4 data warehouse implementation trends based on ScienceSoft’s latest real-life projects:

Trend 1. Moving to the cloud

  • Scalability and flexibility of a cloud data warehouse.

The inherent scalability of a cloud data warehouse allows for easy adaptation to the changing amount of data and the required processing capacity. Thus, scaling the data volume up and down does not affect the performance of the data warehouse.

  • Flexible pricing options.

Cloud providers offer flexible pricing models (e.g., pay-as-you-go) and discount opportunities for provisioned resources to meet their clients’ technical needs and budgets.

  • Data availability.

Nearly all cloud data warehouses perform consistent backups automatically, which results in 99.99% data availability and fault tolerance.

Trend 2. Turning to Data Warehouse as a Service (DWaaS)

When opting for DWaaS, you eliminate hardware and software acquisition, configuration and maintenance costs. As a DWaaS provider performs data warehouse administration and management, there is no need to hire an in-house team for managing the data storage infrastructure.

Trend 3. Big data integration into data warehouse

Combining historical business data with less structured data from big data sources (machine data, transactional data, public data, etc.) provides for uncovering hidden data patterns and correlations and getting insights that can drive business-improving actions, which is a huge step towards accurate forecasting and boosted profit.

Trend 4. Implementing a real-time data warehouse

A real-time DWH provides analytical insights as soon as new data arrives. It means the DWH can send immediate responses (e.g., notifications, automatic action triggers, intelligent recommendations) to specific events right as they happen. Such solutions are used to enhance customer experience, strengthen security, and optimize business costs and processes.

Data Warehouse Implementation Steps

The process of implementing a data warehouse is closely bound to particular business needs and objectives, so the data warehouse implementation steps may differ or merge depending on the project specificity and scale. Based on 18-year experience in delivering data warehousing solutions, ScienceSoft outlines some general steps that are typical of most data warehouse implementation projects:


Data warehouse feasibility study

Duration: 2-4 days

Determining data warehouse implementation project viability considering:

  • Business objectives (strategic and tactical) to achieve with data warehouse implementation.
  • Company’s, departments’ and business users’ needs and expectations from the data warehouse implementation project.
  • A high-level project management scenario with data warehouse implementation project deliverables, skills required, time and costs involved, potential problems.

We usually deliver a PoC to assess the data warehouse implementation viability. The estimated PoC delivery time is 2-3 weeks.





Duration: 3-15 days

Business needs analysis and elicitation of high-level data warehouse requirements, including, but not limited to:

  • Number of data source systems to be integrated.
  • Source data volume and complexity, etc.

During the discovery step, our consultants analyze relevant documentation, interview and hold brainstorming sessions with all stakeholders to collect their needs, goals, and vision of the successful data warehousing project implementation. It helps understand their priorities, plan the development process accordingly and as a result - provide a satisfactory end product.




Data warehouse conceptualization and platform selection

Duration: 2-15 days

Identification of the desired data warehouse feature set and optimal data warehouse software (DWH database, ETL/ELT tool) selection.

Factors to be taken into account:

  • Data sources and data analytics infrastructure in use (if any).
  • Number of data flows to be implemented.
  • Data security requirements, etc.



Business planning

Duration: 2-15 days
  • Defining data warehouse implementation project deliverables and timeframes.
  • Designing project risk management and mitigation plans.
  • Estimating data warehouse implementation costs and DWH TCO.

After evaluating data warehouse TCO, you are ready to estimate the return on investment (ROI) and choose the optimal deployment option ((multi-)cloud, on-premises or hybrid).

Our practice has shown that effective data warehouse implementation project planning can help reduce project time and budget by up to 30%. To achieve that, we carefully elaborate on the findings of the preceding stages.




Data warehouse system analysis and architecture design

Duration: 20-40 days

Among key activities at this stage are:

  • Detailed analysis of each data source with its data types, volume, structure, formats, and more.
  • Identification and analysis of existing data quality issues.
  • Building a valid data model.
  • Identifying entities’ types (e.g., products, vendors, customers) and attributes (identifiers), relations between entities.
  • Mapping objects, etc.
  • Designing ETL/ELT processes for data integration and data flow control.



Development and stabilization

Duration: 5-6 months
  • Data warehouse platform customization.
  • Data sources integration (including adaptation of source systems).
  • Developing ETL/ELT pipelines (including data validation) and ETL/ELT testing.
  • Data warehouse performance testing.

To deliver a data warehouse in the shortest time possible, in our projects we opt for DevOps-driven iterative development – it assures the quickness and frequency of releases without sacrificing the solution’s quality.




Data warehouse launch

Duration: 3-10 days

Introducing the data warehouse solution to end users: depending on data warehouse size and complexity, it can be done on a step-by-step basis.




Data warehouse support and evolution

Duration: throughout the whole data warehouse solution lifetime
  • Iterative data warehouse evolution (adopting changes in the source systems, expanding data flows, etc.)
  • Supporting evolving storage and analytics needs by adding new data sources while preserving high data quality.
  • ETL/ELT performance tuning.
  • Monitoring/adjusting data warehouse performance and availability.

DevOps engineer

Sets up the data warehouse software development infrastructure, automates and streamlines development and release processes by introducing CI/CD pipelines, monitors data warehouse performance, availability, and security.

Sourcing Models

In-house data warehouse implementation

The company has full control over a data warehouse implementation project.

Caution: Not to delay or compromise the project, there should be the sufficient amount of resources and expertise.

Technical resources are partially outsourced

Augmenting the in-house tech team with a vendor’s resources to perform such activities as data warehouse design, implementation or support. The company has substantial control over the implementation project.

Caution: High requirements to in-house competencies. Additionally, there should be effective communication between all stakeholders to avoid project delays.

Technical resources are fully outsourced

Minimized risk of the resource overprovisioning after the project completion.

Caution: High requirements to in-house PM and BA competencies.

In-house project sponsor, everything else is outsourced

Minimized risk of data warehouse implementation project delays or failures due to resource unavailability. A vendor takes on full responsibility for the data warehouse implementation project and all related risks.

Caution: Increased vendor-related risks due to high vendor dependency.
