Denodo Platform 9 Certified Developer Professional study guide
Denodo Platform 9 Certified Developer Professional · Work through your exam, one topic at a time.
The Denodo Platform 9 Certified Developer Professional is a vendor credential aimed at developers and data engineers who build and operate solutions on the Denodo data virtualization platform. It validates that you can work across the full development surface of the product rather than only one module: connecting to and modeling source systems, building base and derived views, tuning queries, applying security and masking, publishing data services, configuring caching and acceleration, scheduling data movement jobs, promoting artifacts through the development lifecycle, and understanding core architecture and administration tasks. The Denodo Platform 9 Certified Developer Professional study guide has 9 sections and about 3,618 words.
01Virtual DataPort: Data Sources, Base Views, and Connection Management
This domain covers how Virtual DataPort (VDP) reaches external systems and turns each connection into a base view - the only view type that reads real data. Expect questions on driver and adapter selection, connection-pool settings, credential modes, schema inference and the effect of connection parameters on execution.
432 words, about 2 min02Virtual DataPort: Derived Views, Joins, Unions, and Query Optimization
Derived views combine, filter and reshape base views without moving data. The exam probes join types and conditions, set operations, aggregation, and above all how VDP decides what runs at the source versus in its own engine.
414 words, about 2 min03Data Modeling and Governance: Associations, Tags, and Metadata
This domain is about the meaning layered on top of views: relationships between them, classification labels, and the descriptive metadata that makes a virtual model usable and auditable. An association declares that a field in one view relates to a field in another, with a cardinality of 1:1, 1:N or N:M and optional role names for each end.
430 words, about 2 min04Data Security: Authentication, Authorization, and Data Masking
Security questions ask who gets in, what they may run, which rows they see and which values are hidden. Expect authentication modes, privilege grants at database/folder/view level, row filters, and masking designs.
431 words, about 2 min05Data Services and APIs: REST, SOAP, OData, and GraphQL Publishing
Publishing turns views and stored procedures into consumable APIs. Questions compare REST, SOAP, OData and GraphQL, and test how authentication, resource naming and limits are configured.
382 words, about 2 min06Caching, Query Acceleration, and Performance Tuning
This domain covers how VDP avoids repeated work: cache modes and invalidation, precomputed summaries, MPP acceleration, and the tuning levers visible in the execution plan. Cache is configured per view with modes off, partial and full.
378 words, about 2 min07Denodo Scheduler: Jobs, Data Movement, and Incremental Loads
The Scheduler is a separate server that automates work: exports, cache refreshes, data movement between systems, replication and maintenance. Expect job anatomy, triggers, dependencies and incremental-load mechanics.
396 words, about 2 min08Denodo Design Studio and Solution Manager: Development Lifecycle and Deployment
This domain covers how artifacts move from a developer's environment to test and production without manual rework: projects, revisions, solutions, environments and deployment. Design Studio is the web-based development environment for building databases, data sources, views and services.
368 words, about 2 min09Denodo Platform Architecture, Installation, and Administration
Architecture questions identify the components, their ports and metadata stores, and how a production topology differs from a single-server evaluation install. Administration covers configuration, startup, logging and backups.
