2. Agenda
1. Why a Data Fabric ?
2. Components of Data Fabric Architectures
3. Denodo Logical Data Fabric

The core of the matter is being able to consolidate many diverse data sources in an
efficient manner by allowing trusted data to be delivered from all relevant data
sources to all relevant data consumers through one common layer.

The Data fabric focuses on automating the process integration, transformation,
preparation, curation, security, governance, and orchestration to enable analytics
and insights quickly for business success.

Query Engine
Delegate processing to data sources
▪ Transparently switch workloads according to cost or
performance
Most advanced execution engine for distributed scenarios
▪ Unique techniques automatically rewrite user queries to
maximize pushdown
▪ Leverage MPP capabilities of data sources to deal with large
data volumes
Advancing Caching / Acceleration Mechanisms
▪ Selectively materialize subsets of the data for protecting data
sources and query acceleration

Integrated ETL / ELT Support: Remote Tables
Create table in any location
Load with data from any other data source
Examples:
• Data Lake
management
• Replicate data in lake
when needed
• Data Science
• Move data to Spark
after initial analysis
• Cloud Migrations
• Replicate and
update data to
cloud system

Often triggered from
Scheduler

Fewer copies of
personal data.

Conformance with Semantic Models

Create or Import Semantic Models:
• RDF/OWL, Power Designer, ER Studio, Erwin,
IBM Data Architect…
“Contract” between modelers and developers
• Ensures data complies with standard data
models and governance rules
Allows parallel development of consuming
applications and virtual models

14. MY RECOMENDATIONS
Data Marketplace for the Business:
Discover and contextualize interesting
datasets
Search, query and Prepare Data.
Consume with any visualization /
reporting tool
Personalized recommendations
and shortcuts to most
used datasets. Think Netflix, but your data
