Integrated application of eODL 2J.Fischer
Outline• eODL – a simple language
• model views for the development components
• eODL is technology independent
• representation forms of eODL
• component development
• integration of legacy components
Integrated application of eODL 3J.Fischer
Applications with eODL
• eODL talk about COs, assemblies, nodes and links
• COs provides some functionalities• collections and interconnections are called
assemblies – structure of the system
• nodes and links– structure of target environment
• deployment– assignment
Integrated application of eODL 4J.Fischer
• supporting the development of software components for - existing and - coming-up component platforms
in combination with other techniques
• for modelling the components from different views: - computational, Mapping: eODL SDL- implementation, - deployment
technology independent from the used platforms
• for that mappings to technology dependent platforms exist- implementation languages
supported by the target component platform Mapping: eODLCIDL C++, SDL C++…
eODL – a simple Language
Integrated application of eODL 5J.Fischer
• superset of ITU-IDL (CORBA IDL 2.4.2)where concepts of
- name scoping- data types- operational signatures and interfaces
are well-defined
• not designed - for (complete) behaviour description - for implementation of the components (business logic)
• but attention - behaviour description and implementation are possible
after mapping

Representation forms of eODL
(1)textual IDL-like
(2)XML as exchange format (defined by XMI)
(3)graficalnot yet available, but possiblecandidate: UML-Profile for eODL
advantage: UML tools are available

Integration of legacy components
• bound to fixed component platform– need mapping to that kind of platform– map component layout to eODL level– use at eODL level for assemblies

Integration of legacy components
• bound to fixed component platform– need mapping to that kind of platform– map component layout to eODL level– use at eODL level for assemblies
• standalone software component– target component platform ?
• what will be the preferred platform
– realize wrapper component for the standalone software component
• design at eODL level• deployment at platform level
