1What is data virtualization and how does Denodo implement it?
A.A data integration approach that creates a unified logical layer over multiple heterogeneous data sources without physically moving data; Denodo implements this through Virtual DataPort (VDP)
B.A process of copying all enterprise data into a central data warehouse for unified querying
C.A technique for compressing database files to reduce storage costs across multiple systems
D.A cloud migration strategy that replicates on-premise databases to cloud object storage
Explanation: Data virtualization provides real-time, on-demand access to data across disparate sources (databases, APIs, files, cloud services) through a logical integration layer, without ETL-style physical data movement. Denodo's Virtual DataPort (VDP) is the core engine that creates and exposes these virtual views while federating queries to underlying sources.
2In Denodo Virtual DataPort, what is a 'base view'?
A.A view that maps directly to a data source — a table, query result, stored procedure, API endpoint, or file — from an underlying system
B.A view that aggregates data from multiple derived views into a summary
C.A view created by joining two or more base views using SQL join conditions
D.A view that caches query results in the Denodo cache database
Explanation: A base view in Denodo VDP is the lowest-level mapping object — it represents a single data source object such as a database table, stored procedure result, REST API response, flat file, or web service. Base views are created by Denodo's data source adapters and define the schema of data available from each source.
3In Denodo VDP, what is a 'derived view'?
A.A view built on top of base views or other derived views using operations such as joins, unions, projections, selections, and aggregations
B.A view automatically generated by Denodo's AI engine based on query patterns
C.A physical copy of a base view's data stored in the Denodo cache database
D.A view exported from Denodo and imported into a downstream BI tool
Explanation: A derived view in Denodo VDP is a logical view created by combining or transforming one or more base or derived views using relational operations: join, union, intersection, minus, selection (WHERE filter), projection (column selection), aggregation, and flattening. Derived views form the logical integration layer in Denodo's architecture.
4What is VQL (Virtual Query Language) in Denodo?
A.Denodo's SQL-like language for creating, managing, and querying virtual views, data sources, and security elements in Virtual DataPort
B.A visual query language using drag-and-drop components instead of text syntax
C.A proprietary compression format used by Denodo for caching data efficiently
D.An API specification format used by Denodo for REST web service connections
Explanation: VQL (Virtual Query Language) is Denodo's SQL-derived language used for all operations in Virtual DataPort — including CREATE DATASOURCE, CREATE WRAPPER, CREATE VIEW, SELECT, INSERT, GRANT, and CONTEXT statements. It is the primary programmatic interface for administering and querying Denodo VDP.
5In Denodo VDP, what is a 'JOIN view' and how is it created?
A.A derived view that combines rows from two or more views based on a join condition, created using the JOIN derived view operation in VDP
B.A base view created from a SQL JOIN query defined in a JDBC data source
C.A system-generated view that joins all tables within a single database schema automatically
D.A view created by merging two cached result sets from the Denodo cache database
Explanation: A JOIN view is a derived view type in Denodo VDP that combines rows from two or more input views based on join conditions (inner, left outer, right outer, full outer, or cross join). It is created in the VDP Administration Tool by selecting the JOIN operation and defining the join condition between the input views.
6What is a 'UNION view' in Denodo VDP and what is it used for?
A.A derived view that combines rows from two or more compatible views into a single result set, used to consolidate similar data from multiple sources
B.A view that creates a universal search interface across all data sources in the VDP server
C.A view that calculates the mathematical union of numeric ranges in two datasets
D.A view that merges the schemas of two views into a single wider schema with all columns
Explanation: A UNION view in Denodo VDP stacks rows from multiple input views (with compatible schemas) into a single result set — analogous to SQL UNION ALL. It is commonly used to consolidate identical or similar data from multiple sources, such as combining sales data from regional databases into a global sales view.
7What does the 'CONTEXT' clause do in a Denodo VQL SELECT statement?
A.It passes query execution hints and configuration parameters — such as cache settings, timeout values, or custom properties — to the VDP execution engine for that specific query
B.It defines the database schema context in which the query executes, similar to SQL USE DATABASE
C.It provides contextual metadata comments attached to the query for auditing purposes
D.It specifies the user authentication context for the query execution
Explanation: The CONTEXT clause in Denodo VQL is appended to SELECT statements to pass runtime hints to the query optimizer and execution engine. Common uses include forcing cache refresh (cache = 'off'), setting timeout values, enabling data movement, or passing custom properties to data source adapters for that specific query execution.
8In Denodo VDP, what are the three main cache modes and how do they differ?
A.Full cache (complete snapshot of all view data), Partial cache (stores only queried subsets), and Incremental cache (appends only new or changed rows to an existing full cache)
B.Read cache (stores query results), Write cache (stores insert operations), and Delete cache (stores deleted rows)
C.Memory cache (in RAM), Disk cache (on SSD), and Network cache (distributed across nodes)
D.Hot cache (refreshes every minute), Warm cache (refreshes daily), and Cold cache (manual refresh only)
Explanation: Denodo VDP offers three cache modes: Full cache loads a complete snapshot of a view's data into the cache database; Partial cache stores only the data for recently executed query conditions; Incremental cache extends a full cache by fetching only rows created or modified after the last cache load, reducing refresh cost for append-heavy datasets.
9What is TTL (Time-To-Live) in Denodo VDP caching?
A.The duration after which cached data is considered stale and the next query will refresh the cache from the data source
B.The maximum time a VQL query is allowed to run before it is automatically cancelled
C.The time a user session remains active before requiring re-authentication
D.The replication delay between the primary VDP server and standby servers
Explanation: TTL (Time-To-Live) in Denodo VDP caching defines how long cached data remains valid. When a query arrives and the cache entry has exceeded its TTL, VDP refreshes the cache by re-querying the data source before returning results. TTL can be set in seconds and controls data freshness vs. performance trade-offs.
10In Denodo VDP, what is 'incremental cache' and what condition must the source view support for it to work?
A.A cache mode that adds only new or changed rows to an existing full cache; it requires the source view to have a column that identifies when records were created or modified (e.g., a timestamp or incremental ID)
B.A cache that incrementally grows by storing every query result without ever deleting old entries
C.A distributed cache where each VDP node stores an incremental partition of the total dataset
D.A cache that incrementally reduces in size by evicting the oldest entries when storage limits are reached
Explanation: Incremental cache in Denodo VDP updates an existing full cache by fetching only records added or changed since the last successful cache load. For this to work, the source view must expose an incremental condition — typically a last_modified timestamp or an auto-incrementing ID — that Denodo uses to construct a WHERE clause fetching only new/changed rows.

Frequently Asked Questions

What is Virtual DataPort (VDP) in Denodo?

Virtual DataPort is Denodo's core data virtualization server. It creates a logical abstraction layer that connects to heterogeneous data sources (databases, web services, files, cloud apps) and exposes integrated, real-time views without physically moving data. Clients query VDP via SQL, JDBC, ODBC, or REST.

What is VQL in Denodo?

VQL (Virtual Query Language) is Denodo's SQL-like language for creating and querying views in Virtual DataPort. It extends standard SQL with data virtualization-specific statements like CREATE DATASOURCE, CREATE WRAPPER, CREATE VIEW, and supports operations like CONTEXT for passing query hints.

What is incremental cache in Denodo?

Incremental cache in Denodo VDP updates an existing full cache by fetching only records created or modified after the last cache load. It requires the base view to expose a timestamp or incremental condition. This reduces refresh cost for large datasets that grow over time.

What is Solution Manager in Denodo?

Solution Manager is Denodo's centralized administration console for managing multiple Denodo environments (development, QA, production). It handles license management, environment promotion, deployment, monitoring, and configuration management across a Denodo installation.

What are row restrictions in Denodo security?

Row restrictions in Denodo VDP limit which rows of a view a user or role can see. They are defined as filter conditions applied automatically to queries by users with the restriction applied, functioning like row-level security in databases — transparently enforced at query time.
