What's inside our DWH solution?

Business values of our enterprise data warehouse for insurance companies

Our data warehouse enables the insurance company to leverage data‑driven insights, optimize operations, and enhance customer experiences, ultimately driving strategic growth and a competitive advantage in a rapidly evolving market.

Enhanced decision‑making through unified data

Our DWH solution consolidates data from various systems — claims, underwriting, customer service, and finance — into a single, reliable source of truth. This unified view enables business leaders to analyze trends, monitor key performance indicators (KPIs), and make data‑driven decisions quickly. With accurate and up‑to‑date insights, insurers can better allocate resources and respond to market changes proactively.

Enhanced desicion picture

Increased operational efficiency

By integrating and automating data workflows, a custom data warehouse (DWH) reduces reliance on manual processes and eliminates the need for fragmented spreadsheets. Teams can access consistent, real‑time data without waiting on IT or data analysts. It leads to faster cycle times, fewer errors, and better collaboration across departments.

Deeper customer insights and personalization

With centralized and enriched data, insurance companies gain a holistic view of customer behavior, preferences, and risk profiles. This enables more precise segmentation, targeted marketing, and personalized policy offerings. As a result, customer satisfaction increases, and retention improves.

Scalable architecture for future growth

A custom data warehouse (DWH) is built to align with the insurer's specific data landscape and business objectives. It can evolve alongside new data sources, technologies, and analytics needs, offering long‑term flexibility. This scalability ensures that the data infrastructure can support strategic initiatives such as digital transformation and AI adoption.

DWH layers

The Insurance DWH is implemented as a single, monolithic system, where all major layers (STAGE, ODS, CORE, MIS, ADM) reside within a single Oracle database.

  • Stage

    Temporary data area

    Ingestion and
    validation of raw data from sources
  • ODS

    Operational Data Store

    Structured operational view of recent data for reporting and access
  • Core

    Integrated historical data

    Transformation, calculations, and historicization
  • MIS

    Management Information System

    Data marts for analytics, BI, and downstream systems
  • ADM

    Advanced Data Mining

    Exploratory analysis, predictive modeling, and data discovery
DWH_SUPPORT Web Application (control, ETLs/Logs/ Locks/Performance monitoring, Statistic System reports) Real-time Notifications and Prod Incidents Handling Framework DWH Continuous Integration and Continuous Delivery framework based on Jira/Bitbucket/Jenkins and Build tool ADM ODS Stage MIS DWH Core Downstream Systems Reporting Systems BI Systems Analytical reports Upstream Systems Batch flows Real-time flows {} NoSQL databases (Key – value, Documents, Graph) Relational databases (OLTP, OLAP) Flat files (CSV, fixed) Clouds (Azure, GCP, Amazon) dwh-scheme
  • In Data Flow In Data Flow
  • Out Data Flow Out Data Flow
  • Optional Data Flow Optional Data Flow

Note: In our implementation, a monolithic architecture means that all layers reside within a single Oracle instance without being spread across separate platforms, external storage, or data lakes.

Benefits of DWH layers residing within a single place

Note: The STAGE and ODS layers operate at the same logical level, and both contain raw data. Their difference lies in how data is loaded:

  • STAGE: Batch loading (typically once a day)
  • ODS: Real‑time streaming via Kafka

Our approach to DWH: Hybrid architecture

Among key architectural approaches to developing a DWH, we chose the most common ones — Kimball and Inmon because a hybrid architecture combines the strengths of both.

Inmon Architecture (Top‑down)

  • Builds a centralized enterprise DWH using normalized 3NF structures
  • Data marts are built separately
  • Focus on consistency, data governance, and traceability

Kimball Architecture (Bottom‑up)

  • Builds dimensional data marts using star or snowflake schemas
  • Emphasizes facts and dimensions
  • Optimized for BI tool, faster time to value

Benefits of hybrid architecture

The hybrid approach to building an insurance data warehouse enables us to do the following:

Support the needs of business users and analysts:
  • Access consistent data structures
  • Plug in BI tools with minimal transformation
  • Receive timely, accurate reports and KPIs
  • Accelerate decision-making
01
Address the requirements of DWH engineers:
  • Centralized data governance and lineage
  • Reusable ETL components and frameworks
  • Scalable architecture and automated monitoring
  • Operational efficiency and observability
02
Combine Inmon's reliability with Kimball's flexibility and delivery speed 03
Lay a strong basis for growing the architecture's maturity and business values 04

How is DWH controlled?

dwhControl picture

To ensure efficient support and complete control over the Insurance Data Warehouse, we built DWH SUPPORT — a custom web app based on the Oracle APEX platform. It improves day‑to‑day operations, making it easier for teams to monitor, diagnose, and manage complex data flowing across the DWH environment.

With real‑time visibility into ETL processes, interactive dashboards for load status, and built‑in error diagnostics, DWH SUPPORT helps quickly identify and solve issues. It also enables the secure performance of operational tasks directly through the interface — decreasing downtime, enhancing data reliability, and improving operational efficiency.

To enable rapid incident response and real‑time platform monitoring, a specialized bot — DWH ALERTS — was built and integrated with Jira. It provides instant tech alerts, automatically creates support tickets, and gives real‑time updates on data load statuses. So issues are detected and resolved more quickly.

How is BI organized in our DWH for insurance?

The DWH platform uses Oracle BI as its core business intelligence solution. Our team not only delivers the required data infrastructure — such as data marts, aggregations, and metrics — but also has a dedicated BI team that is responsible for the following tasks.

  • Managing OBIEE repositories (physical, logical, and presentation layers)
  • Designing KPIs, subject areas, and interactive dashboards
  • Supporting business requirements and data architecture
  • Collaborating with analysts and business stakeholders
  • Performing end‑to‑end validation of analytical outputs

Involved in the entire development lifecycle, our BI engineers ensure the accuracy and reliability of analytical solutions by leveraging strong domain knowledge and technical data warehouse (DWH) expertise.

Tech stack

We build enterprise‑grade data warehouses, analytics platforms, and data processing systems of any complexity. From classic on‑premise to hybrid and cloud‑native architectures — we deliver end‑to‑end solutions tailored to your business.

What components should a modern DWH tech stack include?

A modern DWH tech stack includes multiple core components to handle data from ingestion to analysis. For data ingestion, tools like Fivetran, Airbyte, Apache Kafka, and AWS Kinesis collect batch and streaming data. Data transformation is handled using dbt, Apache Spark, Databricks, AWS Glue, or Azure Data Factory, often coordinated by orchestration tools like Airflow or Prefect. Processed data is stored in cloud-based warehouses such as Snowflake, Google BigQuery, Amazon Redshift, or Azure Synapse. For business access and insights, the stack includes a semantic layer with dbt Semantic Layer or LookML, and BI tools like Power BI, Tableau, and Looker. Governance is managed with platforms like Collibra, Alation, or Apache Atlas, while Monte Carlo, Great Expectations, and DataDog ensure data quality and monitoring. Security is enforced through IAM, encryption, and data masking, and for enterprise data management, solutions like Informatica MDM or Reltio are used. This modular and scalable setup is suitable for the insurance industry and adaptable across other sectors.
