• Marketing data is in a SaaS app
• API access has high latency
• Maybe we need to cache it locally?
• We need to address incremental
updates
• Sales is in the EDW
• Currently on prem in Oracle
• Planning migration to the cloud
• Can’t disrupt business!

5. 1. Unified Data Access
• What: Connect all data to the logical layer
• Why:
• Back-end complexity is hidden to end users
• IT gains flexibility for change
• Features:
✔ Connectivity to different sources
✔ Abstraction of underlying technology

6. 2. Semantics
• What: Brings additional meaning to data for simpler usage
• Why:
• Presents data to business users in their own language, simplifies
self-service
• Increase reusability and reduces IT requests
• Features
✔ Definition of derived data models
✔ Tagging and documenting

7. 3. Unified Security & Governance
• What: Secure and govern all data in a single place
• Why:
• Simplifies security management, faster and less
error prone
• Business user only see what they are allowed,
across all data assets
• Features:
✔ Tag-based security policies
✔ Lineage, change impact analysis

9. 5. Performance & Scalability
• What:
• Execute queries at scale in the fastest possible way
• Why:
• Provide fast, responsive execution
• Features:
✔ Real-time data integration
✔ Query optimization
✔ AI-based Query Acceleration
✔ Data replication

10. 10
Execution and optimization
Denodo includes an advance execution engine that optimizes
and orchestrates execution across data sources
▪ By default, since Denodo has no data, execution happens in real time
▪ Denodo pushes down execution to sources as much as possible.
▪ For a single source query, data just passes through with minimal overhead
▪ For multi-source queries, Denodo offers a state-of-the art cost based
optimizer with rules engine to generate efficient execution plans, even for
large data volumes
▪ Includes options like MPP execution and on-demand data movement
▪ Denodo also provides a variety of techniques for selective materialization
▪ Query acceleration based on aggregate-awareness techniques
▪ Advanced caching mechanism
▪ And point-to-point replication capabilities

11. 11
Performance – Multi-source optimization
• This approach gives the DV layer a lot of flexibility to take advantage of
processing at the sources, and in turn, reduce data transfers
• The right execution plan is automatically chosen by the optimizer based on the capabilities
of the sources, and cost estimations based on volume and the operations involved

Smart Query Acceleration: AI-based Recommendations
Denodo 8 uses Artificial
Intelligence to automatically
recommend the best summaries
to increase performance
Denodo uses a complex algorithm
that combines usage history and
cost simulations to generate
them

13. 6. Deployment and Operation
• What:
• Integrated capabilities for management and operation of the platform
• Why:
• Reduce operational work for IT and align with modern CI/CD trends
• Features:
✔ Automated cloud provisioning
✔ Monitoring
✔ Team development and revision management

14. 14
Deployment and Operation
In addition to the execution server and development environment, Denodo includes
a full-fledged ecosystem to manage the operation of the platform
▪ Flexible options for on-prem, cloud and containerized deployment
▪ Fully automated deployment models in AWS and Azure managed graphically in Solution
Manager
▪ Integrated scheduler for batch operations
▪ Caching refresh, stats gathering, etc.
▪ Real-time web-based monitoring tool
▪ Graphical management of updates, migrations and backups
▪ APIs for integration with lifecycle management tools (e.g. Jenkins)
