Red Hat Certificate of Expertise in Data Virtualization exam (EX450)

• Developers and architects who will be responsible for modeling and creating federated views of multiple, different data sources using Red Hat JBoss Data Virtualization
• Database administrators who may be involved in a project using Red Hat JBoss Data Virtualization to model and create federated views of multiple, different data sources

There are no prerequisites to take this exam but it is recommended that an individual take Red Hat JBoss Data Virtualization Development (JB450) training course.

Candidates should be able to perform the tasks listed below:

Establish and import data sources

• Import from Flat File Source locally
• Import from Flat File Source ftp
• Import from RDBMS

Federate and transform data

• Use the Teiid Designer wizards to automatically generate data translators
• Understand and update generated translators
• Apply simple data transformations such as Type Casting
• Apply complex transformations inbuilt transformation functions
• Use the various inbuilt translators

VDB Modeling

• Aggregate different typed data stores to create a federated view including:
  • Files (flat and XML)
  • Multiple, different relational database
• Implement SQL logic from distinct data stores
• Understand and implement materialized views

Tuning

• Improve performance by using in memory cache
• Use techniques to bypass caches as needed
• Tune caching behavior for specific requirements

Reporting/Data export

• Create READ procedure
• Expose procedure results as XML or JSON
• Expose data as RestFul services
• Understand and anticipate performance issues

Runtime

• Package and deploy virtual databases
• Understand how to use Teiid Designer to control and mange the Data Virtualization runtime

Someone who holds a Certificate of Expertise in Data Virtualization is able to perform the following tasks:

• Start, stop and manage deployments on the Data Virtualization runtime
• Model and create federated views from divergent data sources including flat files and relational databases
• Transform data from divergent data sources to create new, business ready data views
• Create virtual procedures to provide customized and/or optimized data views
• Use effective techniques to improve the performance of federated data views
• Expose federated data as RESTFul services

The Red Hat® Certificate of Expertise in Data Virtualization exam tests candidates' skills and knowledge in the use of Red Hat Data Virtualization to integrate multiple data sources.
