Whole Platform presentation at Language Workbench Competition 2011

1. Whole Platform
LWC11 Submission
Riccardo Solmi, Enrico Persiani

2. Outline
• Whole Platform highlights
• LWC11 Solution (for offline reading)
• LWC11 Solution live demo

3. Whole Platform
highlights
• Vertically Integrated System
• Domain level Agile Development
• Mature for your business
(for offline reading)

4. Vertically Integrated
System
• Fresh design and implementation of all of the
enabling technologies
• no mashup of existing tools and languages
• From frameworks to domain languages
• metamodeling, behavior, graphical,
notations, and persistences frameworks
• Models, Grammars, Actions, Queries,
Workflows, Tests, Artifacts, ..., DSLs

5. Domain level Agile
Development
• Full domain level solutions with graphical
auto-layouted notations
• no abstractions on top of 3GL text code
• Agile approach
• hot deploy even incomplete or updated
models (structure, behavior, and tooling)
• testing with automation facilities

6. Mature for your
business
• Open Source licence (LGPL)
• Real world applications (TASGroup)
• used in production since 2005
• more than 40 products
• worldwide customers
• Electronic Money and Payment Systems
markets

7. Mature for business
• In TASGroup the Whole Platform is used for:
• Data formats (~20 SEPA, ~900 FIN, ~300 RNI)
• ~200 configurations of Software Product Lines
• ~1000 Workflows
• ~300 test cases
• Database archiving and migration
• Rich clients: Desktop (Eclipse), Web (JSF, GWT)

8. Mature for business
• Performance (SepaCreditTransfer, per server)
• 44000 transactions per hour
• including for each: parsing, validation,
enrichment, translation, assembly, bulking,
tracing, routing

21. Compare Models

22. Compare Grammars

23. Solution Overview
• two grammars for Entities and Instances
• one metamodel for ER
• two actions for behavior and tooling
• a solution deployer
• a testsuite

24. Grammars DSL
• familiar BNF terminology
• enriched with intentional constructs
• graphical railroad notation
• parser, unparser, notation, and derived
metamodel

25. Entities and Instances
grammars

26. Examples

27. Models DSL
• focused on structure definition
• compact tabular notation
• scale to large languages
• interpreter + generator

28. ER metamodel

29. Actions DSL
• familiar tooling terminology
• mimic Eclipse toolbar and context menu notation

30. Entities and Instances
Actions

31. Instances Validator

32. Queries DSL
• familiar query terminology (XPath, SQL)
• safe traversal semantics
• is all about sequences
• templates with variables (Commons DSL)
• JIT compiler to iterator framework

33. Entities to ER
in out

34. Entities to XML
in out

35. Artifacts
generator

36. Derived
properties
• Generate the Entities metamodel
from the grammar
• Add an optional behavior feature
• Redeploy and add the behavior

37. Debugging

38. Tests DSL
• familiar unit testing terminology (JUnit 4)
• fluent assertions
• domain notations in fragments
• interpreter + generator

39. Testsuite

40. Tests

41. Autocomplete
