What is the Modern Data Stack?
The modern data stack is a new generation data infrastructure that collects, transforms, and analyzes data in real-time using cloud-native tools. Unlike the traditional “big data” approach, it focuses on data quality and processability rather than data volume. At DNOMIA, we provide end-to-end consulting for e-commerce companies in this transformation.
Why is the Big Data Era Ending?
Over the past 10 years, companies have collected petabytes of data and built massive data lakes. However, according to DNOMIA research, over 90% of collected data is never used. This creates a “data swamp” instead of a “data lake.”
| Old Approach | DNOMIA Approach |
|---|---|
| How much data are we collecting? | How much value are we generating from data? |
| Batch processing (daily/weekly) | Real-time streaming |
| IT-dependent reporting | Self-service BI |
| Reactive analysis | Predictive insights |
The 3 Pillars of Smart Data Transformation
1. Data Quality > Data Quantity
A data lake full of low-quality data is actually a data swamp. DNOMIA Data Quality Framework:
- Data Observability: 24/7 data quality monitoring
- Data Lineage: Track data’s journey from source to destination
- Data Contracts: Quality SLAs between producers and consumers
2. Real-Time Insights
Traditional batch processing is giving way to streaming analytics:
- Instant customer behavior analysis
- Real-time anomaly detection
- Event-driven architecture (Kafka, Flink)
3. AI-Augmented Analytics
Artificial intelligence is democratizing data analysis. Results we’ve seen at DNOMIA clients:
- 60% faster insight generation
- 3x increase in self-service report usage
- 40% reduction in IT dependency
DNOMIA Data Maturity Framework
We assess your company’s data maturity at 4 levels:
| Level | Definition | Characteristics |
|---|---|---|
| Level 1: Reactive | Data exists but unused | Excel reports, manual processes |
| Level 2: Defined | Basic BI established | Dashboards exist, IT-dependent |
| Level 3: Proactive | Self-service analytics | Data culture established |
| Level 4: Predictive | AI-driven decisions | Automatic optimization |
Most e-commerce companies are between Level 1-2. At DNOMIA, we map the journey to Level 4.

Where to Start?
Start in 4 steps with DNOMIA Data Maturity Assessment:
- Assess current state: What data is being collected? How much is being used?
- Define business questions: Start with questions that need answers, before technology
- Look for quick wins: Choose a pilot project that can create value within 30 days
- Measure and iterate: Establish a continuous improvement cycle
