Towards Efficient Loading of Change-Based Models

Abstract

Abstract. This paper proposes and evaluates an efficient approach for loading models stored in a change-based format. The work builds on language-independent change-based persistence (CBP) of models conforming to object-oriented metamodelling architectures such as MOF and EMF, an approach which persists a model's editing history rather than its current state. We evaluate the performance of the proposed loading approach and assess its impact on saving change-based models. Our results show that the proposed approach significantly improves loading times compared to the baseline CBP loading approach, and has a negligible impact on saving.

Towards Efficient Comparison of Change-Based Models.

“…CBP is an alternative approach to state-based persistence (SBP) of models. Instead of persisting snapshots of the state of a model -which is the default behaviour of frameworks such as EMF -CBP persists the entire history of change events of a model [YRPK18a]. For example, in the SBP approach, when we save the UML class diagram in Fig.…”

“…In our previous work [YKP17,YRPK18a,YRPK18b], we proposed change-based persistence (CBP) as an alternative approach to state-based persistence of EMF models [SBMP08]. Instead of persisting models as XMI snapshots, in the proposed approach models are persisted as a complete history of changes.…”
