Compuware Corporation 4 What are Transformations ?

Compuware Corporation 5 Breakfast Classes UML expressed in CWM Breakfast Tables expressed in MOF UML expressed in CWM MOF expressed in Formal Languages and Specifications Lang. X Specification A expressed in

Compuware Corporation 6 A Specification is a well-formed Structure with Meaning Lang. X well-formed according structure

Compuware Corporation 7 Transformations Lang. Y Specification B Lang. X Specification A expressed in Transformation C Transformation Definition Z defined by

Compuware Corporation 8 Example CWM Breakfast Tables UML Breakfast Classes expressed in B.Transformation defined by O/R Transform. Definition

Compuware Corporation 9 Example XML Schema UML XML Schema MOF UML expressed in U.Transformation defined by XMI

Compuware Corporation 10 well-formed according Matching and Deriving Patterns Lang. Y Lang. X well-formed according Transformation Definition Z derived patterns matched patterns defined by transformation

Compuware Corporation 11 well-formed according What is a Transformation ? Lang. Y Lang. X well-formed according Transformation Definition Z derived patterns matched patterns ? defined by

Compuware Corporation 12 well-formed according well-formed according A Transformation is a well- form Inter-Specification Structure Lang. Y Lang. X well-formed according Transformation Definition Z transformation derived patterns matched patterns

Compuware Corporation 13 well-formed according well-formed according Matching and Deriving Patterns Lang. Y Lang. X well-formed according Transformation Definition Z derived patterns transformation matched patterns

Compuware Corporation 14 well-formed according well-formed according Derivation of Patterns implies both Creation and Deletion Lang. Y Lang. X well-formed according Transformation Definition Z transformation C

Compuware Corporation 15 well-formed according well-formed according Derivation of Patterns implies both Creation and Deletion Lang. Y Lang. X well-formed according Transformation Definition Z transformation C

Compuware Corporation 16 well-formed according well-formed according Derivation of Patterns implies both Creation and Deletion Lang. Y Lang. X well-formed according Transformation Definition Z transformation C

Compuware Corporation 17 well-formed according well-formed according Some Transformations are Bi-Directional Lang. Y Lang. X well-formed according Transformation Definition Z transformation C matched patterns derived patterns

Compuware Corporation 18 Lang. Y Spec. B expressed in Transformations and MOF Lang. X Spec. A expressed in Transformation C Transformation Definition Z defined by MOF expressed in XMOF expressed in

Compuware Corporation 19 A transformation is a inter-specification structure with automated matching and deriving of patterns Creations, deletions and changes of elements are implied by the pattern constraints in the transformation definition Some transformations are bi-directional Transformations transform instances of models defined with MOF Transformations Conclusions

Compuware Corporation 20 Important Requirements for a Transformation Language Leverages current Model languages like MOF and OCL Defines transformations in a structural (non imperative) fashion Defines Transformations in an executable way Does NOT defines anything about the ‘how’ and the ‘when’ of the execution process Is user (writer & reader) friendly

Compuware Corporation 21 XMOF Compuware’s and SUN’s solution to the MOF 2.0 Q/V/T RFP Fulfills all the requirements as mentioned in this presentation and much more Is based on and reuses MOF / UML-infrastructure and OCL Models executable transformations Is a lean and mean extension to class modeling Is implemented and working Is very beautiful
