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.

Time: From 6-9 months

Data warehouse implementation steps: Feasibility study, discovery, data warehouse conceptualization and platform selection, business planning, data warehouse system analysis and architecture design, development and launch, support and evolution.

Cost: Starts from $70,000

Team: A PM, a BA, a DWH system analyst, DWH solution architect, data engineer, QA and DevOps engineers.

Data Warehouse Implementation Trends

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)

Minimizing data administration efforts.

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.

Data Warehouse Implementation Plan

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 our 16-year experience in delivering data warehousing solutions, we outline some general steps that are typical of most data warehouse implementation projects:


Data warehouse feasibility study




Data warehouse conceptualization and platform selection


Business planning


Data warehouse system analysis and architecture design


Development and stabilization


Data warehouse launch


Data warehouse support and evolution

Talents Required for Data Warehouse Implementation

Project manager

Defines and communicates data warehouse implementation project objectives, manages project scope, costs, timing and quality.

Business analyst

Elicits and documents data warehouse solution’s functional and non-functional requirements (including data warehouse solution’s building blocks, integrations with data source systems, etc.), technical limitations (if any).

Data warehouse system analyst

Analyses data sources (and their dependencies) and data analytics software (if any) to be integrated with the data warehouse solution. Reviews data loaded into the data warehouse for accuracy.

Data warehouse solution architect

Draws up data warehouse architecture requirements. Designs data warehouse architecture that supports high availability, performance, scalability, and security of the data warehouse solution.

Data engineer

Develops a data model and its structures, draws up data flows (based on the system analyst’s input). Develops, tests and maintains a data pipeline routing source data to the data warehouse. Builds the ETL/ELT process.

Quality assurance engineer

Conducts data warehouse solution’s requirements analysis, defines a test strategy, and designs an optimal test environment to simulate real-time data warehouse scenarios. Executes test cases to evaluate functional and non-functional aspects of the data warehouse system.

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.

Data Warehouse Implementation Costs

A data warehouse implementation project, which involves developing a 10GB data warehouse with data integration and data cleansing processes, may vary from $225,000 to $485,000 (excluding software licensing and other regular fees).

The major factors that influence data warehouse implementation costs are:

  • Number of data sources (ERP, CRM, SCM, etc.) and their complexity (whether a data model description exists or not; if the data model differs from the new data warehouse data model).
  • Data volume.
  • Complexity of data cleansing.
  • Number of data tables and columns used for analysis.
  • Required security level and policies.
  • Data warehouse velocity, scalability, and fault tolerance.
