2. Agenda
● What is Teiid
● Basic Usage
● Teiid Tooling
● Short File Demo
● Teiid Internals
● Heterogenous Sources Demo
● Enterprise Data Services
● How do you fit in?

3. What is Teiid?

4. What it is?

5. How does it work?
● Views that integrate data sources
(Databases, Files, WS)
● Teiid goes further...

6. Enterprise Information Integration

7. Relational Abstraction Flat File

8. Recap of Introduction
● Scalable information integration through a
relational abstraction
● Real-time
● Open Source

9. Teiid History
● MetaMatrix 1999
● Red Hat acquired MetaMetrix in 2007
● Teiid
● DNA - ModeShape
● Current version is 8.2 Alpha2 on AS7

10. Teiid Basics for
Information Integrator

11. Simple Deployment

12. Virtual Databases (VDBs)
JAR like
file

13. Translator
● Adapts queries to specific data source
● Built-in
○ Oracle
○ File
○ WS
○ Salesforce
● Really an extension point

14. Teiid
Teiid Designer

15. Teiid Designer Modeling
● Model Driven
● Create Virtual Databases
● Creating data sources (files,databases)
● Deploy
● Broken with version 8

16. Teiid Designer
● Eclipse 3.7.2
● Teiid Designer 7.x
● http://www.jboss.org/teiiddesigner
● JBoss Developer Studio

17. From Designer
● Transforming Source Model to View Model

18. Dynamic VDB
● XML
● Create Virtual Views and Procedures

19. Short Demo

20. Short Demo
● Setup Teiid in JBoss AS 7
● Designer http://www.jboss.org/teiiddesigner/downloads
● Samples http://www.jboss.org/teiiddesigner/downloads/examples
● In Eclipse "Import > General > Existing
Projects.... > Select archive file: text-file-
example.zip"
● From eclipse Readme > Example
instructions
● Skip some steps! Designer doesn't work with
Teiid 8

21. Teiid Tooling

22. Teiid Console
● Deploying VDB
● Deploying Datasources
● Changing Translator Properties (e.g. table
pattern)

23. Teiid Adminshell
● Something like SqlPlus
● Groovy based
● Connect to VDB and run quries
● Monitor queries
● Automation

24. Practical Considerations
● Static integration through Designer VDB
● Dynamic VDBs through XML
● Deploying by copy/paste
● Testing through SQuirrel or your JDBC code

25. Teiid Internals

26. Teiid Architecture

27. Parsing the Query
select * FROM EmployeeView.EmployeeInfo
● Note this actually calls procedure

28. To Object State
select * FROM EmployeeView.EmployeeInfo
● QueryParser.parse(String sql)
● Query.class
○ private Select select;
■ MultipleElementSymbol (*)
○ private From from;
■ UnaryFromSymbol (EmployeeView.
EmployeeInfo)

29. Process Plan
● Similar to Query Plans
● Tree like structure
● Optimization

30. To Process Plan
● Optimization takes place
● public static ProcessPlan optimizePlan (Query)
ProjectNode(0) output=[emp.lastName, emp.firstName] [emp.lastName, emp.
firstName]
JoinNode(1) [NESTED TABLE JOIN] [CROSS JOIN] output=[emp.
lastName, emp.firstName]
ProjectNode(2) output=[f.file] [EmployeeData.getTextFiles.file]
AccessNode(3) output=[EmployeeData.getTextFiles.file, EmployeeData.
getTextFiles.filePath] EXEC EmployeeData.getTextFiles('EmployeeData.txt')
TextTableNode(4) output=[emp.lastName, emp.firstName]

31. Features/Challanges
● Memory usage (passivation)
● Time Slicing
● Federated Joins

32. Simple Federation

33. Limitations
● No DDL
● Not enforcing PK/FK

34. Notable Dependencies

35. Java development!
● Maven
● Subversion - moving to GitHub soon
● JIRA issue tracking

36. JBoss Deps
● Netty
● JBossTS
● JBossCache
● JGroups

37. Java CC
● Parsing queries
● Generated
● Tutorial code {{ .... }}

38. Twitter Demo

39. Red Hat Enterprise Data Services
● Builts on Teiid
● Support
● Why? Check out TEIID-1714 (https://issues.
jboss.org/browse/TEIID-1714)
● Certified solution (https://access.redhat.
com/knowledge/articles/112503)

40. Conclusion
● SOA - data services
● Uses JCA
● Open source
○ Heavily refactored
○ Automatized tests
○ Features rapidly added

41. Your Part

42. Why develop?
● Learn Java, be an expert!
● Become Data Guru
● No GUI (Teiid Designer is separate project)
