• These materials are prepared only for the students enrolled in the course Distributed Software Development (DSD) at the Department of Computer Science and Engineering, University of Mälardalen, Västerås, Sweden and at the Faculty of Electrical Engineering and Computing, University of Zagreb, Croatia (year 2009/2010).
• For all other purposes, authors’ written permission is needed!• The purpose of these materials is to help students in better
understanding of lectures in DSD and not their replacement!

Overview
• What is the goal of TransfoREMES?
- Model Transformation
1/10/2010
Overview
• What is REMES ?– REsource Model for Embedded Systems.– Used for formal modeling and analysis of Embedded
resources for storage, energy, communication and computation.
• Why is it important to model ES resources ?– Limited availability of computing resources– Early design decisions can affect the system's overall resource
consumption
• What is the need for Transformation ?– UML Diagrams lack formal description for resource consumption– It facilitates designers to analyze the system effectively.

Transformation Testing
1/10/2010
•Model Comparison between the actual and expected target model
• The comparison between the two models contain two sets Mapping set (MS) Difference set (DS)
• Mapping set contains all the matching pairs of elements
• Difference set aims to detect I. New differencesII. Delete differencesIII. Change differences

DSD Challenges & Experiences
• Technical Challenges- Finalizing UML metamodel- ATL was new to each member- Choosing an appropriate UML visualization tool compatible with the metamodel
• Technical Experiences- Adopting alternate approach for Risk mitigation.- Learnt new tools & technologies

DSD Challenges & Experiences
• Communication Challenges- Expressing ideas effectively - Face to face discussions between FER and Supervisor
• Communication Experiences- Face to face meetings, Skype conferences conclude with productive outcomes.- Frequent discussions with supervisor cleared ambiguities.
22
DSD Challenges & Experiences• Management Challenges “Patience, persistence and perspiration make an
unbeatable combination for success”
• Management Experiences- Work appreciation motivated the team- Meeting deadlines through effective planning- Promoting amiable working environment for efficient
outputs.

DSD Challenges & Experiences
• Cultural Challenges- Chances of misunderstandings- Varying accents of team members- Respect for time
• Cultural Experiences- Social interactions through Facebook -Learnt about each others etiquettes, culture, festivals and country- Avoided audio Skype conference.- No delayed meetings as everyone was on time
