Challenge

One of the main goals of the project is to support the tax authority's (NAV) auditing tasks with efficient and easily interpretable reports and analytical tools. These tools enable tax inspectors to quickly identify anomalies, patterns, and potential irregularities in toll payments.

When designing the data structure, we had to consider the NAV's data warehouse standards to ensure compatibility and seamless integration. The structure needed to be flexible to accommodate future expansions and modifications, such as changes in law or the introduction of new data sources. The data model includes the structure for ticketing events, vehicle data, payment information, and other relevant data.

A key and innovative element of the project is the mapping report feature. This visualization tool allows NAV's auditing staff to analyze toll data in a geographical context, identifying traffic patterns and potential irregularities.

How we helped?

• Scheduled Implementation of Data Download Logic
• Data is downloaded from various sources using Oracle Service Bus, followed by validation, transformation, and loading into the data warehouse, taking into account performance and security requirements.
• Data Structure Development
• A well-structured data model has been created in the staging area and the data warehouse to support efficient data processing and storage.
• Data Cleaning, Normalization, and Storage
• • - Data Cleaning: Identifying erroneous, incomplete, or redundant data and establishing appropriate responses.
    
  • - Normalization: Minimizing data redundancy and ensuring data integrity.
    
  • - Storage: Developing and creating appropriate data structures for efficient and secure data storage.
• Implementation of Data Warehouse Loaders
• Creating and establishing data warehouse loaders for all logically related data units. The design of ETL (Extract, Transform, Load) processes ensures efficient and reliable loading of data into the warehouse. Daily data refresh mechanisms have been implemented to ensure up-to-date information.
• DataMart and Reporting
• Designing and developing a data mart for the data. Data has been presented through Oracle BI reports.
• Visual Representation of Data on Maps
• Creating maps to visualize toll data under various conditions.
• Development of Efficient Reports and Analytical Tools
• We designed tools and reports that support the tax authority's (NAV) auditing tasks and are easily interpretable for tax inspectors.
• Facilitating Anomaly and Pattern Detection
• The tools we developed enable rapid anomaly detection, assisting inspectors in identifying irregularities in toll payments.
• Supporting the Work of Tax Inspectors
• Our solutions ensure that inspectors can perform their duties more effectively, with faster access to the necessary analysis and reports.
